Though written in 2017, the post on revisiting drop/release stitch lace 1 has had new swatches and updated design ideas added. It includes information on how to use punchcards intended for other fabrics as possible design ideas and a cumulative list of previous posts on drop stitch lace.
The Brother publications have offered this idea for end release drop stitch in one of their volumes of punchcard patterns. 
Many published designs recommend beginning the knitting with the racking handle in the center position, 5 of 1-10 positions in Brother, and 0 of 6, 3-3 in Passap. Often the starting position is relative and when a lot of racking is involved, they may be varied, though not the sequences in terms of the number of movements, to different starting points if that seems to offer an easier way to track position numbers. It is one of the many things that once the method is sorted may be adjusted to personal preference. Some of my swatches below were started with the racking position on 10, some with it on 5.
Many knitters in forums appear to have success with end release drop stitch. My experience has been that episodic release of the stitches even as often as after 2 rows knit yields far more predictable results. It is how I worked my shawls produced in the technique, including these two, knit in days when I did not always photograph all my pieces 
Giving end release another go, this was my initial needle set up. With the majority of the needles in work on the main bed, the larger stitches in the final fabric will dominate. The stitches after the cast on have been transferred down to the ribber. 
The work on the machine, with stitches on the main bed released at the end of the swatch. 
There is a long stitch DBJ single color pattern happening which may prove to be an interesting fabric if no stitches are dropped, to preserve it, all stitches would be transferred to the top bed, and bound off.
Here the racking took place in single positions after every knit row. Dropping stitches on completion of the swatch, particularly along the edges was so fiddly and such a nuisance I simply gave up in spots, some indicated by red dots. 
This watch had stitches released at the end of each shape, racking in the top portion occurred after every 2 rows knit
Here the same design was knit using different yarns. The first is knit using the same blue wool, the second a tightly spun rayon. 
So many fabrics can be automated, sometimes the fabric is a vague look-alike cousin of the original, close enough to be a reasonable compromise. Slip stitch patterning across the top bed can offer a quick solution to bypassing a lot of hand manipulation. Assuming that was possible for this fabric, my starting repeat, 10X30 pixels: 
and the plan would be to knit it in a 40 stitch swatch, placed in a way so that the “mock racking” would move equally from side to side. Working on a larger than needed canvas, the design can be placed on a magnified work area with a visible grid, at the chosen starting point. If the background is left as white in BW images, moving repeat spacing may erase black pixels as copy and paste in place are used. The solution is to make the background transparent using the Layer menu, as explained in other posts on using Gimp. 
To save the repeat as a BW bmp or png, remove the alpha channel 
The final repeat is 40 stitches wide, 34 high, 
with blank rows added to its top to serve as a place to drop stitches and have knitting happening on the ribber only.
Depending on the download program or the knitting machine model number, repeats are automatically mirrored, so if direction matters, mirroring of the repeat may need to be performed once more.
Why the repeat will not work for drop stitch: if the KC is set to slip in both directions, the function will happen on all needles in work on the top bed. On any given row, only black pixels (or punched holes) will knit. The slipped/ skipped stitches keep elongating until a black pixel replaces the white one in that needle location. The degree of elongation is illustrated in the chart in color for part of the repeat, the yellow marks the widest gap between knit stitches. If knit as is the repeat will soon cause serious knitting problems and carriage jams. 
Though designing for one type of fabric may fail, this repeat or similar could be used successfully double bed in other ways, using hand transfers on the top bed or down to the ribber. In this case, I chose to transfer down to the ribber, which avoids concerns about restoring correct needle selection, and the repeat was not mirrored for use on my 930, so the resulting knit appears as drawn on the purl side, but is mirrored on the knit side.
The fabric is far removed from the drop stitch idea, but as for drop stitch lace, stitches after the cast on are transferred to the bottom bed.
Newly selected empty needles will create eyelets with the next 2 carriage passes, and texture will appear on both sides at the transfer down locations.
The shapes created do not travel on the knitting bed any longer.
End needle selection needs to be canceled at any time that slip stitch patterning is used and does not occur on every needle on the top bed.
If the pattern is to be interrupted by all knit rows here seen as rows with no preselection in the programmed repeat, then any needles with stitches on them need to be transferred down to the bottom bed before continuing to knit.
As preselection begins again, those needles should be filled by picking up from the stitches below them on the ribber, and then the process may be repeated.

DBJ: more than 2 colors per row 3

Reducing the number of rows on the front of DBJ fabrics and the associated elongation of the planned design matters so some designers far more than others, at times only in specific projects.
It may remain something in one’s wheelhouse that is not worth doing because one can.
When I was knitting garments and art-to-wear pieces I found I preferred to work in 2 color dbj, plying thin, sometimes space-dyed yarns and dropping threads, replacing them with the next shade in the chosen color wheel spaces to add more colors per row.
Long before computer interfaces that made downloads or even color separations easy, most knit artists used punchcard machines, often the Passap Duomatic, lining up long individual panels to create large, non-repetitive images, Nicki Hitz Edson among them. That said, the topic has remained interesting to me.
In the post written on 12/19, an option was presented for having each color in each design row knit only once rather than twice. Tables in a Numbers spreadsheet were used to produce the necessary color separation.
The present goal is to repeat the separation process using other possible DIY methods.
To review: the dbj automated separations for more than 2 colors per row with the exception of the Heart of Pluto one when using the Ayab interface generally result in each color, in each design row knitting twice. This is also true of default console separations in the E6000.
The yarn for this fabric needs to be thinner, colors easily become muddied if not chosen with care, there are 6 carriage passes for each design row of knitting, and charts and downloadable repeats including all knit rows become considerably longer.
When experimenting with colors keep careful notes about your own color placement in each yarn changer location, they may not match those assigned by the download program or in the original chart.
DAK offers the option of printing templates for its DBJ separation methods. They may be used as guides for using the designs outside the program, whether for download to electronic knitting machines or to be followed in punching cards.
Files may be opened in the DAK Graphic Studio Module with the intent to convert them to stps for use in its universe or to adapt the design for other uses outside it.
My experience with several trials of small images in 3 colors is that the resulting design conversion is faulty. The file size morphed into a 40X40 repeat as opposed to the original 12X14, leaving no option but to draw the design from scratch in the stitch design module.
My third attempt finally got my 3 colors represented properly, but still in the 40X40 pixel size, not worth troubleshooting, redrawing the motif is far easier and more straightforward. 
Img2 track will perform the separation but does not offer a charted view or template for it. It has the added interesting function of immediately reducing the file by half because upon download the image will be lengthened automatically by a default setting to double length on the Brother machine. 
The issue may be addressed by doubling the file in length prior to selecting it with img2track or the stretch factor in the program may be changed to 2, also before selecting the file for separation.
I prefer to manipulate files as needed prior to opening them in any program for download, believe it makes patterning errors easier to correct, and avoids forgetting to change settings when returning to knitting the particular repeat again. 
In the January 2021 post, I suggested manually pushing back to B position all needles in work prior to the carriages returning to the left on every other row as one way to reduce the resulting elongation in the designs. Here the plan is to achieve it by amending the color separation and its needle selections.
One of the advantages of DIY is that the color order in the separation may easily be matched by that in the color changer.
Repeats should contain an even number of rows and may also contain rows where not all colors are in use. The first starting repeat: 
The often published convention in performing dbj color separations is to begin ordering the colors based on the number of cells they occupy in the first row, here the yellow would be followed by black and then red. Other programs start with the first pixel color on the left by default.
After drawing the repeat in Stitch Designer, working with Dak choosing color separation C, and exploring print options, one may obtain a template. Its screengrab serves as a guide to tracing pixels, the results match the Gimp separation which follows.
DAK automatically mirrors the motifs horizontally prior to working with them in any way. The mirrored DAK template compared to the in-progress Gimp separation: 
My goal is to produce the fabric with each color in each design row knitting only once by changing the separation, the function performed automatically by Ayab’s HOP code.
This technique applies to double bed work only, is not suitable for single bed 3 colors per row slip stitch.
The backing used is bird’s eye on the ribber, with slip stitch set in both directions and using both lili buttons. The result is that every other stitch knits on the pass to the right in any color used, the alternate needles knit on the return to the left completing one full row of knitting in that single color on the purl side.
The main bed needles are preselected on the way to the left, create stitches on the way to the right, as they flatline. Since there is no needle selection, as the carriages return to the left, no main bed needles will knit, resulting in only one row in the color being carried knitting on the top bed as well. Needle preselection continues to be made for the next row to be knit after the color change.
This makes for a more balanced fabric unless colors begin being skipped for multiple rows, in which case the ribber stitches may even form small ridges and the main bed stitches will become more elongated until the skipped color is repeated.
Working using Gimp alone
It is possible to color separate using only Gimp. One of the tricks is to use significant magnification, along with the view grid and snap-to-grid options when working with developing or editing designs.
In the latest version of Gimp for Mac, using the fuzzy select tool,
selecting pixel color segments allows for color substitutions when converting charts to BW prior to the final png save.
It may be achieved by clicking on a single color, followed by holding the shift key, clicking on more colored pixels for multiple selections regardless of color, and then selecting bucket fill with the replacement color. Using select by color, followed by using the bucket fill tool, changes that particular color globally throughout the repeat.
As selections are made, dotted lines outline selections until after the color change and the image has been fixed. 
Colors are fixed by choosing the rectangle tool and clicking in the work window outside the image, those dotted lines will then disappear.
This separation begins with black, the first color pixel on the left.
The original image is scaled X3 in height to 11X30, 
the file resulting from the separation will be scaled again X2 prior to knitting the repeat after it has been completed.
Copy and paste the scaled X3 results on a larger new file so that color markers for each row may be added, horizontal guides every three rows help define each expanded, now 3-row color sequence.
Following the color rotation markings for each row, erase colors unlike it and not represented in each design row to its right, so where the black marker pixel is on the left yellow and red are erased, where the yellow marker pixel is black and red are, and where the red marker is black and yellow are. That single row with no color red is left blank.
Those extra columns on the left are cropped prior to converting the file to BW. The results on the far right would need to be used double length, whether scaled before the final file save or after download, prior to knitting. Depending on the machine and the program used for download, if the direction of the design matters, the result may need to be mirrored as well. 
Developing the test png on the elongated repeat
My test png, mirrored for download to the 930.
I had color changer issues with yarns being picked up 2 at a time fairly frequently, which were likely static related and improved following a rare use of yarn spray and a humidifier.
Having end needle selection, KCI on the main bed helped avoid issues with edge stitches not forming properly.
I tend to grab yarns randomly when swatching. The resulting colorways are not planned for use in finished items, they are explorations that help illuminate subsequent choices.
The yarns used in the swatch are of three different weights, so tension needed to be adjusted to accommodate the thickest yarn, resulting in more elongation of some of the stitches on the front of the fabric. The latter might be far less noticeable when knitting with thin, equal weight yarn selections. The design can be easily identified and it is also seen that colors are indeed knitting a single time for each design row. There is an exception on a single row toward the bottom of the swatch, where blue and white have knit together during tension adjustments on both beds. 
One drawback to this method is that since it is downloaded as a fair isle, the capacity of the machine to offer prompts and reminders as to which color is in use and which selection should follow in knitting 3 color dbj is lost.
Testing the concept on a design where more rows have less than 3 colors represented. The repeat is slightly modified, from the one used in the second 12/19 post 
Here it is shown modified, with rows containing fewer than 3 colors marked. 
Separating the repeat using only Gimp:
the file on the right rendered double length
and in turn with the second of every pair of black pixel rows erased 
the comparison between the two 
I left the color changer set up in the same sequence and yarns used in the previous swatch, so colors do not match their placement in the charted design. I stopped knitting when the color changer carried 2 colors across a whole row, and I did not notice the error until I had reached the other side. A repair can be made easily, but I chose to stop since the repeat was previously untested. There is a dropped stitch also missed on the purl side, an easy repair when a piece is finished.
The fabric is narrow as a result of the slip settings, the cast on and beginning and ending rows of knitting need to be adjusted or they will stretch out quite a bit compared to the remaining knit.
The proof of concept with each color in each design row knitting only once: 
The 12/19 post also compares its repeat knit using the initial double-length file to the one resulting from the amended repeat with each row knitting only once for each color in each design row 
Multiple color drop stitch lace using img2track and more
Many fabrics allow samples to be knit using the proper color separation and released just before binding off. Samples and designs are included in several of my previous posts.
End-release depends on how the repeat is programmed but does not always produce good results. As can happen in any fabric, what works in swatch size may not when knitting larger pieces. Fuzzy yarn is problematic in many knitting techniques, it is best avoided in these fabrics. No matter the yarn, after knitting longer pieces, I have found sections that simply refuse to unravel. In addition, if long stitch shapes are distributed on knit striped grounds, the release must happen at a minimum when the top of each shape is reached. A sample with drop-stitch interrupted by all knit rows with only one color released. 
The repeats for designs may be self-separated to suit.
For more than 2 colors per row, the built-in separation in img2track may be used, where any number of colors are selected for each design row and repeated twice. Passap separates for 2 colors with each pixel knitting twice on every row by default, but in Japanese machines, the pattern needs to be separated and programmed using other means.
The knitting method suggested here should work with more than 2 colors per row separated by the software.
The post on Using Layers in Gimp for color separations illustrated a method for obtaining the necessary file to match those built-in variations when working in only two colors. The repeat is one that was separated and used in a previous post 
Here the file is separated quickly using Layer menus in Gimp alone 
Three variations of the final png files are shared 
The last appeared the most interesting visually to me when tiled 
This is the appearance when a different design was entered in img2track. The separated file 3 color file in BW is not shared. 
The method for knitting the pattern: the long stitches are formed by loops that are created on the top bed and dropped on the following row.
This is the method I used in my early dropped stitch samples: to begin with, cast on for every other needle rib, knit 2 circular rows followed by one-row all knit rib, transfer all main bed stitches to the ribber. For an open stitch cast on directions and photos see the post.
The pitch for every other needle 
Set up needles on both beds for every needle rib with an extra needle in work at each end on the main bed, cancel end needle selection (KC II). With the main bed needles in the B position, set the knit carriage to slip in both directions so as not to pick up loops across the whole row on its way to the left. Change the pitch for when working on every needle on both beds. 
Make the first pass toward the color changer, needles will be preselected for the first pattern row
COL: the ribber remains set to knit every needle, the main bed to slip in both directions. A piece of tape in front of needle butts of needles in A position aside the edge of needles with stitches on them on each side helps keep from accidentally moving extra needles into work when dropping whole rows of stitches
COL: change color, as carriage moves to the right, selected needles will pick up loops on the main bed that will form the long stitches when dropped, while the next row of pattern is preselected, so by the time the carriage has reached the right side of the machine, the repeated needles selection is still present
COR: using any convenient tool (I use the edge of a piece of garter bar or ribber cast on comb), bring all needles in work out to E, and use the same tool to return all stitches to B position. The loops formed on the main bed will be released forming the long stitches: check that all needles are indeed empty and that loops are free and between the beds
As the carriage moves to the left again toward the color changer, the ribber only will knit all stitches, needles on the main bed will be preselected for the next row of long stitches, and selected needles do not knit until the next carriage passes from left to right.
COR: colors are changed every 2 rows
Ayab users have a different alternative for knitting this fabric as described in the post, using the circular ribber option. Instructions are given for dropping a single color or both. 
I cannot imagine manually dropping stitches after every row of loop formation on the top bed for any large piece in this manner. As time passed, I developed a hack for using a second knit carriage with a modified sinker plate. 
Anyone with a compatible second knit carriage may use it with the resulting modification to knit a variety of fabrics much more easily, including any that would require the ribber settings changed in both directions, more convenient if the action is required every even number of rows.
Back to drop stitch in 2 colors (or more) using img2track, changing the base design to a small geometric shape. The 8 stitch repeat scaled X 4 in length as separated in the previous post to 8 stitches by 32 rows is used in the following samples. 
Rather than relying on manipulating it in width or height and programming each repeat the changes in my swatches were made using variation key selections on my 930.
This type of fabric is best knit using a yarn with no memory, which will allow for retaining the blocked shape. The elongated stitches can have a peek-through quality that will allow for solid knit in a different color, an undergarment, or even bare skin to show through.
Working with small geometric designs helps to develop a sense of the change in its aspect ratio as the original is scaled and knit in different widths and lengths.
Use any separation that allows for knitting each color pixel in each design row twice.
Begin with carriages on the right / COR
After EON cast-on 
and knitting the first full row from left to right, transfer the top bed stitches to the ribber. Place needles in work on the top bed in the B position with the first and last outside those in work on the opposite bed. This will allow for edge stitches to be dropped in the pattern as well. With the transition planned for every needle rib, the pitch needs to be adjusted accordingly 
The second carriage, C2 is set to KCII as well. It will be advancing the design with each pass as well and will drop loops on the first pass, preselect for the subsequent pattern row on the next
COR: using the paired carriages set the knit carriage to slip in both directions so as to avoid picking up loops on every needle in work on the top bed, the first row is knit on the ribber only toward the color changer.
Download the repeat.
Program it for the width of the needle bed.
Cancel end needle selection on the top bed, KCII
The separation is technically entered as a fair isle design, variation keys for altering the repeat in the individual machine brand ie. double width or double height may still be used.
While moving to the left the first pattern row is preselected.
COL: When the left is reached, change color, the top bed remains set to slip in both directions, the ribber to knit in both throughout.
Before moving to the right for a single time push selected needles back to B so as not to pick up loops on the way back to the opposite side. The second pattern row is preselected during the move to the right, the ribber knits every stitch
COR: knit to left on creating loops, concurrently the next pattern row is preselected, I prefer to change color at this point leaving the carriages to the far left
C2OR: use the second knit carriage with the hacked sinker plate set for plain knitting, make 2 passes with no yarn in its yarn feeder. The first pass drops the stitches. The second pass returns it to the right leaving all needles in the B position. Because no cam buttons are selected in this version, the carriage does not engage the belt as it would if it was also used for advancing patterning.
COL: with the new color no loops are picked up on the way to the right, needles preselect for the next loop row created when moving from left to right
COR: knit back to left creating loops
C2OR: use the second carriage set for plain knitting to drop loops on as it moves to the left, needles are flatlined in B on its return to the right
It is easy to identify the last color used by looking at the ribber. At the completion of each stitch drop, with COL, ribber stitches will clearly be in the last color used.
COL: with the new color no loops are picked on the way to the right, they will be formed on the second pass returning carriages back to the left.
C2OR: use the second carriage for 2 passes
Repeat the last 2 steps until the desired length is reached
Transfer all stitches to the top bed, and create a loose bind-off tested on the test swatch.
The sampled repeats were altered using variation keys in the 930
8X32
16X32 
16X64 
The transition in aspect ratio as the original repeat used on the right is changed to double its width 
Here the comparison is made to the double-wide repeat also doubled in length
The elongated stitches allow objects behind them to peek through 
Another 2 color variation 
Previous posts include samples isolated on striped grounds, using 2 colors.
Adding a third color can make the overall appearance muddy and small designs can appear lost. One such in the post 
Here the goal is to use the img2 track separation, maintaining the same color change rotation in each piece.
Reviewing points to consider: in more than 2 colors dbj separations, the double-length variation key is set automatically except in the 950i, where it needs to be set manually.
In knitting drop stitch, the repeat chosen must have each color present in each design row unless the shapes are deliberately altered with solid color stripes in each color. The software is smart enough to recognize any design rows in which a color is not represented.
In conventional dbj, this keeps the design continuous, but in drop stitch, those extra rows will produce an all-knit stripe interrupting the overall design.
The software scales the height of the motif to half the original, due to the fact that the double-length variation key is automatically turned on, restoring the original aspect ratio, the loaded PNG needs to be the original repeat scaled to double its height.
In DIY a small design will likely be less recognizable than larger ones, but working with one can help one understand how stitches are formed.
The initial design is 6 stitches by 7 rows. 
It was stretched in width since the fabric elongates the design, and in height because to software will, in turn, reduce that by half to 14X12. 
The tiled potential appearance as a dbj fabric:
In the first sample three carriages are used:
after the basic cast-on, transfer and set up needles as described for all variations.
To use the second knit carriage to drop stitches, the first preselection row is made from left to right with the color 1. As the pass is made to the right, no needles on the top bed pick up loops, the ribber knits in that color, and preselection for the next row of knitting is made.
As the carriage returns to the left the first row of loops for the long stitches is formed, and the ribber knits the second row in that same color.
With both carriages to the far left push the button selection for the next color selection. The number prompts for color changes by the machine will be off by a row during this process.
With the second knit carriage and its altered sinker plate on the right set only to knit make two passes, returning it to the far right. The first pass drops the loops, and the second pass returns empty needles to the B position, creating the long stitches.
The paired carriages will knit only on the ribber as they move from the left to the right again, preselecting for the next row of loops. They will place loops in the pattern on the top bed needles as they return to the left, and knit a second row on the ribber.
With carriages to the far left push the button selection for the next color selection.
Use the knit carriage for two passes from right to left, repeating the two steps for the length of the piece.
When the top of the piece is reached, drop any loops on the top bed before knitting a row on the ribber and preparing for transferring stitches to the top bed and binding off.
Only one set of loops is created in each color.
What of end release? because all 3 colors are present in every row, the design is suitable. The first preselection row is from right to left.
I found the combined carriages harder to push, and the knitting wanting to ride up toward the ribber bed needles.
The bottom of the swatch has loops released before a transition to plain knit simply exchanging colors every 2 rows until the end of the test was reached. The top duplicates the effect achieved above by pushing preselected needles back to the B position with a tool before moving with the new color from left to right. 
Side-by-side comparisons: 
If the end release fabric is preferred but the stitches riding up are a nuisance, the carriages are hard to push, not all stitches release on a larger swatch, or a slightly fuzzy yarn is used the same result is it possible once again using the modified knit carriage to drop stitches making passes from the right?
The problem with that concept: if the knit carriage or any other tool is used
periodically to drop stitches in a long piece when it moves across the row, it drops on the first pass, and leaves needles in B position on the second pass when
returning to the right. As knitting resumes with both carriages, no loops are picked up on the first pass to the right, so the pattern with colors dropping for 2 consecutive rows is interrupted, resulting in a patterning error. Selectively dropping stitches while maintaining proper needle preselection is impractical.
Also, if the intent is to use the knit carriage to select and drop stitches for 2 rows out of every 4, the motif would need to be lengthened several times. I found when programming the far longer repeat the software refused to make the proper needle selection, switching every 2 rows rather than repeating the same multiple times. That aside, the number of passes required becomes daunting.
Changing color selection and order may make the individual shapes more noticeable: 
Any published or self-drawn separation for 3 colors per row patterning including every color in every row of the original design may be used, programmed as a single bed design, and knit for end release.
This swatch is only 24 stitches wide, it was a start in an attempt to place a better-defined geometric shape on a striped ground, with spaces where not every color is represented in every row between repeats. Its dbj version has some interesting surface texture on the reverse It is only part of the finished piece. 
The same yarns and tensions as in the previous samples. Two of the problems with end release reared their heads: the color changer side formed too short floats producing a side edge a different length than the other, and several stitches were difficult to drop from the top to the bottom of the knit, with the yarn even breaking in some spots. 
Working with only 2 colors makes the process for me far more predictable and manageable.

Using Layers in Gimp for color separations
2023 The layers menu in Gimp 2.10.34 no longer offers the difference mode.
From the manual: “If you need to stay compatible with older GIMP versions or you need to use the legacy layer modes for other reasons, look for the icon to the right of the layer modes selection.
This drop-down menu will let you choose between Default and Legacy. If you choose the latter, the layer modes list will only show the legacy layer modes and all modes will have “(legacy)” behind their name (the selected mode will use the short version (l). ”
To make the dialog available: 
click on Legacy to switch mode selections. 
In December 2022 I began to experiment with layer transparency please see the post Gimp Update for Mac 3. 
Over the years I have developed personal methods for creating color separations for many types of knit fabrics, born from lots of experimentation when published resources were absent or extremely limited.
I continued to share methods as they evolved from increasing familiarity with specific programs or as I was introduced to new ones.
Since I began to use paint programs including Gimp I had very limited experience using layers and did not consider how they might be used in color separations for BW knit repeats.
In my last post on fantasy fair isle ribber fabrics, Claudia Scarpa shared her layers method and subsequently published a Youtube video for obtaining a separation for a very similar fabric to the one I developed beginning with a large design motif that in her instance was also placed specifically on a larger ground.
Her method for separations in 2 color work sparked my interest in using the steps to yield knitting patterns for varied textures and stitch types, beginning with dbj.
Using
will display layer options in my Mac on the bottom right side of the screen 
A simple geometric shape 
is scaled in Gimp to twice its height, check that Quality Interpolation is set to None. I have sometimes had issues with scaling in Gimp, particularly when working with small repeats. The cause appears to have been that the Quality, Interpolation, needs to be set to None and may randomly change while working through several steps in processing any image or after a program restart. Arahpaint scaling is still an excellent option for knitters who have it available.
the white ground of the resulting image is rendered transparent by using Color to Alpha 
and will constitute the first layer for the separation process 
Select New Layer from the Layers menu (see chart), choosing the background or foreground color to have a white screen. It will share properties with the alpha repeat such as pixel count, magnification, and the grid view if used.
Use the pencil tool to draw a repeat that will be used to fill the new layer, followed by using the rectangle tool to select what will become the pattern used to bucket fill the whole layer.
The latter may be the smallest possible selection or even that of complete rows as in my chart. 
Copy the selection, and it will be saved to the clipboard and remain available for filling with the pattern unless the program is quit. It may also be saved as a pattern for future use.
After using the rectangle select tool, remember to click in the window outside the image to set the layer before using the bucket fill tool in the pattern fill setting, or the whole layer will simply fill in with a single color. 
In the layers dialogue, use the mouse to drag and drop the alpha image icon for the triangle layer onto the newly created one. The selected icon will appear surrounded by a border when chosen, a new icon will appear during the step. 
Both layers measure the same pixel dimensions, no placement adjustments are necessary. The mode, highlighted here is changed in a later step. 
Color invert the new image 
Click on the downward pointer to the right of Normal and select Difference. The result is a repeat that may then be saved and used doubled in height to knit DBJ in a variety of settings.
Elongation after download can be avoided by working with the same initial image scaled in height X4 and following the same process, saving and using the repeat on the far right. 
The same separation was achieved using other methods in the post on fantasy fair isle.
Possible DBJ settings on Brother machines using the elongated final repeat are shown in this grab, part of the post. EOR refers to a repeat that would require double length after the download, the same machine settings apply to any image created in a double-length format prior to download. 
Are punchcard knitters left out? In the post on the color separation used for the KRC equivalent separation for a punchcard two results were presented, the full card 
and the starting design shown with the color reversed repeat of the above. 
The process begins with obtaining the double-length separation 
after saving the last file on the right as PNG 
discard any files still open. Open the saved png and process it the same way, changing the ground 
Save the last file as png. Punchcard knitters would need to tile the fileX4 in width and height X2 but the final repeat appears different than that in the punchcard post, the proof of success or failure is in the knitting. If the swatch is knit on electronic models, the first preselection row is made from left to right, as it would be if using the built-in color separation. The main bed for this fabric after the preselection row is set to slip in both directions, the ribber, using an even number of needles, is also set to slip in both directions with lili buttons. The 8X32 png 
The result from repeating it twice indicates the separation indeed works. 
When a color separation is downloaded it is used as one would a fair isle. If the motif is representational and direction on the knit side matters, any repeats may have to be mirrored horizontally if they are automatically reversed by either your software prior to download or your machine model after it.
There has been renewed interest in the MK FB group on drop stitch lace recently. I plan to address using this repeat in a future post on knitting the fabric using img2track.

Using the rectangle tool, select a single blue row, after the selection, press and hold down the shift key and repeat selections of multiple rows in the same color. Each selection will be bordered by a dotted line. 
Release the shift key. Click on the rectangle select tool and then again in the work window outside the image to set it. The dotted lines will disappear. The same action is repeated if working on segments of the full file at a time.
Export the fully altered file as PNG ready for download, or print a gridded version to follow in punching a card.

MOSAICS: For proof of concept, I intend to use separations for fabrics accompanied by knit samples in previous posts, beginning with a mosaic one, achieved in the post. The images shown are for the final repeat as separated there are shown at the top of this new image. Below comparisons are made between the original download file and its companion elongated repeat alongside the same developed using Layers
Both results require scaling X2 before knitting, whether by button setting changes in the repeat after download or in Gimp before. 
After reaching the step where the layer mode is changed to Difference (or Exclusion), stop and save the png, using color reverse at this point will revert to previous a previous layers view 
open the saved png in Gimp, use color reverse, then scale the result doubling its height, save the png for download and knitting without changes in any machine settings.

More shapes on ribber fabrics with tuck patterning, fantasy fair isle
Fantasy fair isle is the term often used to refer to dbj fabrics created using tuck settings on either or both beds. Typically in the required color separation used each design row in the repeat is expanded into 4 rows, with the same selection occurring for each color pair of consecutive rows. A tuck/plain combination is used here, with the backing essentially being a striper one, where each color knits every stitch on the ribber on every row.
In this illustration, the blue symbols represent knit stitches on either bed, the red, the tucked stitches on the top bed. The chart represents a single design row expanded into 4, the results would, in turn, be rendered double length in knitting the final fabric. 
The last post related to this topic: 2021/09/07/geometric-shapes-on-ribber-fabrics-with-tuck-stitches-3/
Recently a friend shared images of a punchcard skull pattern she was using in a hat and followed with a query as to the possibility of using the pattern on a mesh grid. The inspiration for the conversation began with this image, the work of Claudia Scarpa. 
The possibility of adding images on a true mesh transfer lace or mesh-like thread lace images may be found in 2021/12/14/to-mesh-or-not-to-mesh-9-more-on-mock-filet-design/
My DIY skull image in a potential thread lace pattern, in a 100X92 pixel png. 
Concurrently the topic of illusion knits on the machine has also resurfaced in FB with some spectacular panels executed using the Garter carriage and changing colors every 2 rows. Some small geometric shapes begin to have a somewhat “similar” appearance using this technique, but as with beauty, the success in the imitation is in the eye of the beholder.
The techniques involved: my proof of concept was knit using img2track on a 930. Traditionally two-color designs may be opened and then downloaded, using the standard dbj built-in KRC function for the color separation, not suitable for this dbj version, while for designs in 3 or more colors the program will separate the repeat in a way that each color for each design row is knit twice, the separation required here.
At this point, the color separation is executed by filling in pixels and observing a variety of rules. DAK produces templates of jacquard separations of varied types that may be printed for use outside its universe. The same file may be screengrabbed, traced, and redrawn pixel by pixel for use in a Brother download using other download software.
Passap by default separates knits for 2 color DBJ with each color for each design row knitting twice mode. Tucking on either or both beds is made easier because of the way stitches are formed on the Passap beds, along with the use of strippers which push down on tuck loops with each pass, ensuring that they will knit off properly. The fabric widens considerably when off the machine, requiring loose cast-ons and bind-offs. The dbj variant, dubbed fantasy fair isle, is often used to create lap or quilt blankets.
The Passap built-in reader techniques that are often recommended for large knit pieces ie blankets using the same design are 186 for throw size, 187 for lap blankets, and 183 for crib quilts. All three share the fact that the front bed pushers are selected in pattern in the up/knitting position alternating with the down/slip/tuck position alternating every 2 rows, producing the jacquard discussed here.
Slip settings produce narrow, short results, tuck short and wide ones. For non-Passap knitters, N is Passapese for plain knit, KX is tuck with patterning on the front/ knit bed, and AX for tuck patterning on the back/ribber bed.
Back in 2018, I began another post I meant to return to on traveling between the two brands.
My Passap E6000 manual is filled with scribbled notes from decades ago, expanding on how each technique may be used for a variety of fabrics. 
In Fantasy Fairisle knitting using 187 with alternating up and down pushers on the back bed and AX with 2 arrow keys would match Brother ribber knitting with lili buttons used on an even number of needles set to tuck.
Working with the large skull image the setting of knit every row on the ribber and tuck in both directions on the knit bed is used as in technique 186, with a critical difference. Passap knitters may download the original black and white image while for Brother knitting a color separation is required.
The original skull image is 100 pixels wide by 92 high.
Converting the white ground layer behind the skull to alpha produces an image on a clear ground that can be placed exactly where desired on a new file with a white ground using the grid and guides
The alpha double long skull, now 100 by 184 pixels 
For the 1-pixel grid in Gimp to be visible on an editable image, a magnification of at least 800 is required. The options offered by default
can be changed to suit by simply typing in a new number.
As described in other posts including in Gimp update for Mac2, I chose to mark every other row with a red pixel, making it easier to track color-inverting every other row. This is achieved by selecting the rows with red dots using the rectangle tool one row at a time and choosing Invert from the colors menu. The red dot will also change color, making it easy to locate converted rows in more complex patterns. The dotted blue line is a guide for placement.

the trimmed 98X182 png 
doubled in length once more to 98X364 
Knitting process on a 930 using img2track:
the 930 has a tiny brain, so the image is broken down by the software into multiple tracks of 96, 134, and 134 respectively. One of the critical differences when using this type of DBJ color separation is that the first preselection row is made from right to left toward the color changer rather than from left to right as in KRC separated 2 colors DBJ.
The first and last needles are in work on the ribber to ensure the edge stitch on that bed will knit every row.
The knit carriage is set to KCII, canceling the end needle selection.
Once the first row has been preselected and the planned color is chosen, with COL, set the main bed to tuck in both directions, leave the ribber set to knit, and continue knitting changing color every 2 rows.
In my swatch, the dark contrast color was used for the initial black pixel all-knit rows.
The work on the machine: 
A reminder: in my experience, the Brother cast-on combs are usually chrome-colored, Studio grey, and Passap, and I believe Superba ones were traditionally green. The first 2 were designed for 4.5 mm machines, the latter for 5mm. The different mm spacing does not make the 5 mm combs suitable for casting on on Brother, but they can be poked through the knit in progress. I like to leave the first comb and weights on, insert the new comb closer to the beds, and then move the weight up, and then remove the lower position comb.
There are lots of side-by-side stitches tucking on the main bed, made possible by the fact that each is anchored in place by a knit stitch on the opposite bed.
The tension needs to be set so that the stitches will knit off properly while having tuck loops not so loose as to get hung up on gate pegs. It can take a bit of trial and error to find proper settings and they, in turn, may need to be adjusted again when moving from small swatches to knitting on a far larger number of needles.
The finished piece measures 25 inches in width by 24 in height.
The appearance on the bed set to N, in this case, the ribber: 
Those white lines on the right are spots where the color changer picked up both color threads, a problem that does not occur in Passap knitting, where each color is picked up in its own yarn holder. 
In the Brother model, sometimes the yarn is left in the wrong place below eye level rather than its own individual one corresponding to its button, and both yarns are picked up with the next color change. 
The more textured knit side of the piece,

Claudia Scarpa developed a skull variation using only layers in Gimp 
and has been kind enough to create a Youtube video illustrating the process. The separation is easy and quick as opposed to my more prolonged hack, and I will return to attempt to use it for various fabrics in a follow-up post.
This skull is more compact and better defined than mine. With the double-long original image superimposed on alternating pairs of black and white rows, the resulting png can not be lengthened again as tucking would then occur for 4 rows, not likely possible in a Brother machine. The variant is a very interesting cousin to mine.
In DAK using Method C color separation each color row separates into 2 rows of knitting and when using the result rows do not have to be repeated in pairs but the double-length switch will need to be used in Japanese knitting machines if working within the program. For those intending to use the separation outside the DAK universe, the color separation may be printed, traced/redrawn to create a png or bmp, scaled double length, and used as in the skull swatch. The template for the double long triangle in the post and the associated 24 stitches by 32 rows png, followed by the associated drawn png 
The png doubled in length, 24 stitches by 64 rows. 
This is a small repeat, suitable for punch card machines. The test swatch is knit with the main bed tucking both ways and the ribber knitting every row. 
It is possible to work some repeats on some machines with the ribber also set to tuck both ways with EON needle selection.
In Brother that is achieved by using lili buttons with an even number of needles in work on the ribber. The first and the last needle would be in work on the top bed, the KCI setting is used for end needle selection to ensure that the first and last needles on each side of the piece will knit. I did not find this method workable and soon had to stop because of a loopy mess. 
When using the Dak stitch design module, the color separation is automated. Choose any design repeat. This happens to be a 20X20 one, chosen from the thumbnail assortment, so not suitable for punchcard models. “Printing” the template using choosing the option of using dots rather than squares to represent knit stitches makes the resulting print screengrab easier to trace.

The template was overlayed with a grid in numbers, filling in cells over the dotted areas.
A portion of the work in progress using the generated dbj option C template and tracing it transitioning from template to Numbers, to Gimp: 
The result is screengrabbed, opened in Gimp, converted to BW mode, and scaled to the 20X40 expanded design size. Unless the double-length function in the machine is also used, it will need scaling again to double length prior to download.

In the related swatch patterning is used on 40 stitches by 100 rows. The relaxed fabric when off the machine measures 7 inches by 7 inches and the knit side view reflects the elongation of the design one might observe when using the same color separation in standard striper-backed DBJ. On the bottom, the swatch is stretched and the stitches are set with some casual steaming and pressing to 10.5 to 6.75 inches, gaining the familiar texture appearance seen in so many Passap blankets.
The color differences are due to lighting, with the photos being taken at different times of day. 
For a loose cast-on row, I used a racked version at the same tension as the body of the knit.
For a loose bind-off to accommodate the stretch, I used this method, one of many taught in Passap seminars.
To perform the same on Brother machines: knit the piece, ending with the carriages on the right.
Transfer all the stitches up to the top bed, 
bring the ribber needles up into work between them 
set the ribber to a looser tension number, here it was increased from 4 to 7. Knit one row from right to left, picking up loops on the empty ribber needles 
drop the ribber slightly by using this bracket lever position to elongate the main bed stitches. 
Using a latch tool, beginning with the first stitch on the right, insert the open latch tool into the first stitch on the right, then insert it into the second stitch moving down until the first stitch is behind the hook. Do not allow the second stitch to go behind the latch, keep it in the hook. Pull the latch hook up moving the second stitch through the one behind it, forming the first chain. Repeat across the row, going through the center of each stitch, continuing the chained bind-off. 
A yarn end is pulled through the last stitch and the now completed chained row is secured 
The beds are returned to the up position, and loops and stitches are dropped off all the needles.

Visualizing knit cables 3_ using Numbers and Gimp
As our knitting experience grows, there are likely to be some techniques that engage us and others we choose to avoid completely if possible. Cables are in the latter category for me. I have hand-knit complicated pieces using them but dislike knitting them on the machine immensely. That said, I am periodically drawn to revisiting the topic in my blog, the resulting swatches are as proof of concept.
Small crossings may be used in sequence to create more complex cables, and charts illustrating them may be simplified, using little or even no added color. 
The repeat is 8X8 and the above movement can be seen in the purl view.
Ladders and knit columns between vertical sets of cables make the process easier to track, one needs to be alert to accidentally bringing the ladder back into work resulting in knit stitches, seen in the bottom left of the knit side swatch. 
A spreadsheet table may be created to help with tracking multiple series of cables across a knit and their direction. It can contain as little or as much information as one wishes. Included here: the RC for possible crossings, and their direction on the purl side for machine knitting (reversed for hand knitting). Columns may be added including how many needles are left in or out of work between cable knit spaces or other info. 
It is also possible to print a custom needle tape to place underneath the involved groups of needles instead of marking the needle tape or the knit beds. On a standard km, the needles are 4.5mm apart. A conversion reference for needle spacing point values 
Four needles X 12.75 =51 points, the width of the table cells, which in this instance are all equal in size. Colors and any other info may be added within each cell. Print in landscape orientation, making certain the image is not set to fit the page, but at 100%.
A narrower series of twists are made after every 2 rows knit, the chart shows crossings on the purl side on the left, as opposed as to how they would appear on the knit side on the right 
Which leads to the topic of creating shapes by combining the repeats 
A brief effort containing at least 5 errors leads me to wonder about programming needle selection to help track crossings more easily and avoid mistakes. The center ladder here was latched up during knitting. 
Adding the ribber: the simplest knits using the ribber are made with transfers to the ribber of single or multiple stitches to create what is sometimes called trailing stitches, with cables occurring at determined distances and appearing as knit stitches on a purl ground. Some samples of elongated ribber stitches with crossings on a striped ground may be found in the post on Slip stitch patterns with hand transferred stitches, double bed, the technique may be executed in a single color, or as shown here with color changes every 2 rows. 
If only the knit stitches or purl stitches are crossed on one the same bed when knitting ribs, they will appear so on one side only. One example 
If the start is on the top bed, stitches on the ribber may be created by picking up bars from the top bed 
the yarn above was a 2/8 wool, which refused to cable on the ribber, and having the crossing was preferred to not 
changing to a thinner wool-silk solved the problem. 
Using a punchcard or electronic program to track movements and cabling on the knit bed, each stitch in each pair of punched holes or pixels is crossed over or under the other. This is a very time-consuming fabric, not friendly to distractions or interruptions. Any crossing mistakes in the swatch were due to “operator error”. 
In reviewing the post after linking to it here I realized the now marked punchcard error at its top. The amended longer chart reworked in Numbers is also added to the older post. It is shown here aside from its tiled chart, checking for alignment, a habit developed as my skill and comfort in using spreadsheets grew, 
A png of the repeat, 24 stitches wide by 72 rows 
Tiled for alignment in Gimp as well.
It is possible to use the repeat working 1 X 2 stitch crossings for a very different look.
A large swatch is worth doing before committing to a large piece.
Correcting crossing errors (purple arrows) after the fact will be harder than doing so in some other instances or in a bulkier knit.
Keeping the fabric visible as opposed to between the beds begins to show a pattern on the reverse, which can also guide the direction of movements.
There are spots in this repeat where the center larger cables are not possible because of cables in opposite directions already occurring on either side of the group of selected needles (red arrows).
Transfers occur by bringing single needles forward and crossing pairs of stitches behind them, moving away from the center of the triangular half of the diamond as it is formed. The sequence is retained until after the wider cabled segments occur (black arrow and line), where there is no other needle selection aside from stitches to be crossed.
The number of plain knit stitches between crossings is always even.
The cabled knit areas have a depth that makes them project out and appear almost beaded in texture. 
Assigning colors to crossings in a chart may be helpful or too much info depending on one’s perspective, the bottom of the repeat is on the right. 
Periodically, the topic of reversible cables turns up in discussions for both hand and machine knitting. They are possible when working in ribbing on the knitting machine.
Keep in mind that ribs narrow when off the machine, cables do as well, so a looser tension is generally required, and the basic fact that knit stitches are purl stitches on the other side and vice versa.
Cable crossings are made over purl stitches that separate them or the reverse. Changing rib needle arrangements will result in fabrics that may not always “match”, appearing different on one side from the other.
Using the half-pitch position before any transfer rows brings needles closer together, G carriages may be a boon but may have a hard time knitting the row immediately following the cable crossings and even jam.
On the machines, a 3X3 crossing is likely to be the limit. A general starting guide when trying out repeats is to knit the same number of rows between crossings as there are stitches in the cross, so 6 rows knit before a 3X3 cable.
A published illustration of bringing the ribber into play. 
Creating extra slack if possible on the row before stitches are moved is helpful here as well as when working on the single bed.
Stitches may be crossed on either or both beds. If trying that out, crossing on one bed, knitting a row, then crossing on the other is another thing to try. As with any ribber fabric, the view of results is limited, dropped stitches may be easily missed.
A straightforward idea to test: in a wide vertical rib make cables on both beds, testing whether it is necessary to reverse the direction of the crosses or not, the number of rows to knit plain, etc. The chart shows a staggered arrangement. The number of rows between crossings can be changed to suit. 
In my first test crossings occur on both beds and on the same row. Even using the thinner blue yarn at maximum tension the transfers were hard to execute. I had more success when I added 2 empty needles between the vertical ribs and brought one on each side of each rib into work on the top bed prior to knitting the last row between transfers, creating a bit of extra yarn to ease the crossings.
After the row is knit the same needles are pushed back to A position, dropping the yarn, and crossings are made before continuing to knit.
Results vary depending on the yarn, tension, machine model, and operator patience. The arrows mark the location of what appears to be a damaged needle, the tuck stitches were not deliberately planned. 
Here the repeats are staggered, the edge with the ladder close to the end stitch is shown again to be far less stable than the one with more knit stitches. Spacing is varied, exploring the tolerance for the yarn to be crossed. The setup while working: 
If transfers are made after every 5 rows knit, crossings on multiples of 10 could be assigned to one bed, while row counts containing the number 5 could be made in the other. Sporadically pairs of transfers on the same bed may provide more surface interest.
The set up after transfers to top bed prior to binding off 
Trying out a simple repeat in smaller rib configurations will provide some idea as to whether the technique falls into the love of or not something to do simply because one can.
Charting can happen using the same method as in illustrating crossings in color, with some alterations, sometimes less information is more or enough.
The first repeats were knit with most stitches on the main bed, and a 2 stitch ladder on either side of the ribs involved in cabling to help visually with keeping the stitch location constant. The grey, purl cell blocks are as viewed from the back, the white cells represent stitches on the ribber. 
A: the set up single bed, with needles out of work on each side of the planned cable space, tension is tested and 3X3 crossings every 6 rows are made first only on the single bed
B. the ribber needle configuration is set up
C. the cables are made after transferring ribber stitches up to the top bed, and then the same stitches are returned down to the ribber before continuing to knit
D. the ribber stitches are transferred up to the top bed, and the swatch was bound off. Note the difference in width in areas where no crossings are made.
The step-by-step instructions apply to both instances: the chart shows 4 rows knit between crossings, instead, here 6 rows are knit in both tests.
The photos documenting the 2X2 rib: the single bed starting point
the rib configuration set up 
1. after 5 rows knit, bring an extra needle in work on the top bed to pick up extra yarn for the cross 
2. drop the extra loop, make certain the empty needle returns to A position 
3. transfer all cable ribber needles to top bed 
4. cross the stitches with two three-prong tools 
5. transfer stitches back down to the ribber 
knit 5 rows, repeat steps 1 to 5.
The appearance of each side of the fabric differs
A: the knit was begun on the single bed
B: the ribber configuration was set up
C: cable crossings were made as shown above
D: stitches were transferred to the top bed and bound off 
An attempt at a larger swatch using 1X1 ribs:
the intended concept, 
a custom needle tape 
rib set up for the yellow yarn 
the cable crossings using it were impossible, starting over with a thinner yarn at the same tension 
the ribber may be dropped after transfers up to the main bed, keeping stitches and crossings visible, making it possible to make corrections in any cables if they are needed before re-engaging the ribber and transferring stitches back down 
The concept is an interesting one and many arrangements based on the idea are possible. 
In the above swatches, when any transfers were made to the top bed, after crossings, a row was knit before returning stitches to the ribber. The extra row may or may not be noticeable, depending on the yarn and colors used.
More variants, analyzing columns in color using a crossing over single center stitch first and eliminating the extra knit row, and transferring stitches back down to the ribber immediately after making the cables. The rib will have a tendency to spring back when relaxed and off the machine, so the texture may be hard to see. Using a fiber that allows for some spreading out with some blocking helps to make the work more visible. A reference chart can be developed ahead of time for repeat variations.
The number of rows between crossings can vary. When the crossing row is reached:
A: stitches are moved up from the ribber to the main bed
B: cable crossings are made
C: stitches that had been moved up are returned back to the ribber, keeping the original ribber needle configuration
Assigning colors to columns reveals that stitches are not moved onto the same stitch type when moved over a single, undisturbed, fixed center stitch. 
Shifting the needle arrangements when cabling, moving across a center column of two stitches that remain fixed on the main bed, the cable direction as it would appear on the purl side on the left, the knit side on the right is straightforward here: 
I found the above impossible to knit, even with ladders for extra slack, and the swatch stopped when the yarn broke 
Returning to 1X1 rib, looking at the column alignment in color 
There appears to be enough slack produced in the formation of stitches between beds to make the planned crossings possible.
A: the needles transferred to the top bed
B: crossings are made over the 2 center stitches
C: the stitches that had been moved up to the main bed are now returned to the ribber. Bringing cable stitches out and or up to the hold position helps ensure that they will knit properly on the next carriage passes.
The similarity between both sides of the fabric is increased
From a Brother pub, small crossings for a smocked effect 
The same approach may be used to create fabrics in tubular tuck patterns, easy to execute in one color. Once yarn, possible crossings, and their minimum frequency have been determined, the start of far more complex shapes can be explored using colors to represent the necessary direction of movements before any decisions are made has to how frequently to cross the cables and to get some idea of negative spaces created between traveling stitches. In hand knitting, a purl ground is easier to plan and maintain. 
Adding and removing rows in the tables or even changing colors is easy and quick in a spreadsheet, tiling in repeat with scaled screengrabs provides a quick reference for possible improvements/corrections before any actual knitting takes place 
Visualizing knit cables in color 2_ using Numbers and Gimp
Though this post presents cable movements in colors using multiple stitches, the resulting repeats may be knit by hand or at times on the machines in single color textures and the number of stitches in any column may be reduced or expanded, keeping the direction of the cable crossings the same.
Though DIY charting may not be your goal, perhaps the charts themselves will inspire similar stitch movements. Segments of any of the charts may be clipped, saved, and manipulated for easy versions of other options.
My first published experiment with cables created in vertical columns of alternating colors was in 2012, 
A quick way to imagine variations of the same pattern is to choose segments of the swatch photo and alter their direction and/or placement 
Using the spreadsheet, shifting crossings are imagined, adding a half-drop variation, creating secondary shapes. 
A variation doubling the width of the cable crossing in a half-drop repeat 
In machine knitting, one is looking at the purl side, and the ability to move stitches is often limited by the fact that their placement on a metal bed is fixed distances apart. Simpler repeats can be executed as isolated vertical bands on solid color or striped or even FI grounds, adding the ribber for even more complexity in execution.
Hand knitting makes moving multiple stitches possible more easily, and because the crossings are usually made with the knit side facing, it remains easier to keep track of directions in which to move the stitches.
There are other choices in charting for either, cable crossings happen as a row progresses in hand-knit, and in machine knitting, knitting stops, and crossings are made before continuing with the next row. If color changes are planned every two rows then cables need to have multiples of 4 rows between each set of crossings. Hand-knit possibility on the left, with expanded charting for machine knitting 
I continue to be fond of visualizing results in color in a spreadsheet prior to knitting swatches. As usual, as the sample charts multiply, the techniques often evolve as well for creating them.
Without access to Excel, I am presently using Numbers 11.2 in macOS Monterey 12.0.1, a version with several changes from the previous. Working with shapes does not remain my preferred method, but shapes are useful and worth considering in drafts of charts for many stitch patterns outside this topic.
Notes on my process: to start with, a table is created with enough cells to accommodate more than one repeat of the planned cable crossings in both height and width. I prefer working on a cell size of 20X20 pixels and using magnification if needed to make work details more visible, decreasing it before screengrabs for illustrations here.
The choices for cell border styles may be made both in terms of colors and line quality or eliminated altogether 
To add a shape, in the toolbar, search for shapes and select a category on the left, 
then click on the shape or drag one onto the sheet to add it.
To browse all shapes move the pointer over the shapes pane and scroll down.
It is possible to create and save custom shapes.
To make a shape editable
1: click on a shape to select it
2: choose Format, Shapes and Lines, Make Editable from the format menu at the top of your screen, 
handles will appear. In this case, a red square in each corner, and a small circle on the left side 
3: double click a white handle to change the line from curved to straight, handles represent different types of lines
Squares with a red outline: lines that connect to this point are straight
Circles with a red outline: lines that connect to this point are curved
4: click outside the edge of the shape when done editing it
Saving custom shapes
1: Click a custom shape to select it, then choose Format, Shapes and Lines, Save to My Shapes (from the Format menu at the top of your screen). 
The shape is saved in the My Shapes category of the shapes library, which appears only when you have custom shapes. Shapes appear in the library in the order you create them, this order cannot be changed.
2. Type a name for the shape in the field that appears below it, or click the name to change it.
To delete a custom shape, Control-click it in the shapes library, then choose Delete Shape.
Color choices are the same as for any work with colored cells, for the default palette, left-click on the marked area, and choose from current fill selections 
Choosing custom colors: left-click on fill, then on the colored globe, new selections appear, click on any one of the pencils to select the new color, it will move up from other selections, the change will be reflected, can be undone and repeated several times 
Creating the first cable crossing shape: choose the square from the basic shapes, if the first plan is to work across 3 cells, change its size to the width of 60 pixels, 20X3, and single height of 20 pixels, also changing colors if desired. To do so, left-click on it, uncheck constrain proportions, and change values to desired ones 
Change its color 
It is a good idea to copy and paste a few shapes outside the table in case they are needed
A: place the shape on the cell grid
B: make the shape editable
C: click on the left upper corner of the shape on the small white square, it will turn red, drag, and place it where desired, and release it
D: repeat with the small white square in the lower right corner, release
E: check image size, adjust to 60 pixels wide, 20 high, make editable again if tweaking is needed,
F: the first crossing shape is completed 
Right-click on the final shape, copy it, and paste it several times on the sheet away from the table.
Copying and pasting shapes on a single cell will fit any image within its borders, to remove it choose the cell, color fill, no fill, from the format menu 
To use the shape, left-click on it, drag it into the desired position.
Cable crossings are usually in pairs, so a companion shape will be needed, 60 pixels wide by 20 high, in a contrasting color, the results of making the larger image editable
The combined images may be created in a paint program such as Gimp and the resulting file, in turn, may be used in a spreadsheet. Pngs can be custom filled with any color of your choice in Gimp or its equivalent 
To draw a straight line in Gimp when applicable, select your preferred brush tool, click the point that begins your line, hold the Shift and Command keys in a Mac, drag the cursor to where you want the line to end. Click the endpoint, this creates a straight line between the two points with your selected brush. After the line is drawn, release the Shift and Command keys.
When charts are for personal use only, individual preference guides visualization methods, considerations for publishing may be different.
Yarn colors may be used in the charts, moving wider columns of stitches may be difficult if not impossible on a machine, but hand knitting opens a different world of opportunities for pattern use.
Working in a spreadsheet is easier for me than only using Gimp.
Seeking out a method for better definition of cable stitches to facilitate following crossings visually, cable crossing rows here are now double-height for added clarity; other choices include showing grid or not, and using BW for stitches crossed to the front in any direction.
Disregarding the grid, each column of color could be any number of stitches wide, while having the grid allows for easy counting of rows. Any chart may be used in knitting using a single color as well. 
Fair isle repeats: when working cables in FI, in addition to tracking cable directions, the needles must be placed in the proper needle positions B and D for correct patterning to continue.
A series of cables executed along vertical lines of the same color. The red border surrounds the full repeat. These illustrations are as they would appear for hand knitting, with crossings made as knitting progresses along the corresponding chart rows on the knit side of the fabric

When using fair isle patterning as a guide to forming cables on the machine, crossing directions matter more since one is no longer simply placing color on like color: this chart transitions from the original idea to the placement of the crossings, a full repeat with their direction reversed based on which color is wanted to travel to the knit side is drawn, and on the far right, the look of the final FI repeat 
Adding a third color, possible intarsia knit as all over pattern or isolated as a panel. Even in hand-knit, the latter may be in a contrasting gauge and joined to pieces of the garment after their completion. 
These repeats may be worked as vertical panels between rows of plain knit or rib 
Symmetry is not always needed, 
MK, adding the ribber: one of the things that may lead to confusion is the use of the term every other needle knitting. If one is working on every needle on both beds, the needles on either bed are centered between those on the opposite one, thus patterning occurring on either bed that becomes EON. Colors are used to track the movement of stitches, not colorwork, which happens on the same needles, either bed, or the plaiting feeder may be used to produce the illusion of additional colors. 
Part of an experimental swatch using the ribber and tuck settings 
In attempting brioche on the machine the color changes happen every 2 rows, so a minimum of 4 rows or a multiple of 4 rows are planned between moving any stitches. Although the same color will be used in the crossings each time, using 2 colors for cable segments may make the chart easier to follow

DAK DBJ color separations, templates, other software
Over the years I have written on an assortment of methods for color separation in knits including DBJ, a summary post with links to previous shares: dbj-and-color-separations-some-previous-posts-links/
and in the-start-of-a-blog-index/
A variety of textures and patterns may be used to achieve fabrics that are very different in appearance, using a very simple pattern along with cam button or lock setting changes. The first chart was generated at that time using Intwined Pattern Studio, a program that for a time appeared to be very promising and then moved on to lack of updates for Mac making it useless in 2013, followed by none for Windows as well, with no successful use of it reported in forums in years, but one may still purchase it 
The manual color separation method for punchcard machines.
The elongated X2 repeat version of the triangle drawn in Gimp 
As for more than 2 colors per row, performing the color separations may be achieved manually, various software is now available for performing the work in instants.
Ayab offers an elegant color separation solution, heart-of-Pluto, that will knit single passes for each color per row on the front of the knit, resulting in 3 color patterns with limited design stretch, and no worries about the placement of one color over any stitches preceding it in the same color on the previous pass.
The difference in the same design being knit with the standard, elongated version, allowing for two passes with the same color before each color change and the Pluto version.

For more information on the various DAK separation charts and related swatches including limitations encountered, see post: DBJ, more than 2 colors per row 4
There is a Russian punchcard site that will allow entering personal repeats or selecting one from their extensive library, where it is possible to obtain related 2-color dbj separations as well. The punchcard color separation may be created manually, a slow process, while the punchcard templates in Dak are achieved with a few, quick clicks of a mouse. The repeat may be created as a graphic file, in my case a png created with Gimp, the elongation in Arah because Gimp fails to scale small repeats cleanly. The image may then be opened as a graphic file,
stitch and row counts should match, and save the stp 
if experimenting with changing selections and this window appears it is OK to click on No 
The separation methods in DAK:
Method C separates each color row into separate rows of knitting, rows do not have to be repeated in pairs, and the double-length switch will need to be used in Japanese knitting machines 
The elongated triangles repeat template is different from what would be produced with the above set at double length, may be used as is to produce a variety of fabrics including quilting
Yarn choice and design make a big difference. Here the yarn is far too thin, and the repeat too narrow in width, but the possible result is illustrated. The main bed is set to slip in both directions throughout. The ribber setting needs to slip in both directions for every other pair of rows. When the ribber slips, the main bed will knit the color that will create the pockets, where there are many single stitches selected here, the KC was set to KC1. When the color is changed and the ribber is set to knit again, stitches in that color will knit on both beds, sealing the fabric in those areas and forming a solid color background on the reverse side. Here the white forms the pockets, and the floats after a pair of passes are seen in this photo. 
Because the yarn is so thin there is a considerable grin through on both sides, the areas marked with arrows indicate where the white pockets were lightly stuffed with yarn ends 
For a review of quilting on machines including Passap see 2018/02/15/revisiting-machine-knit-quilting/, and using a second knit carriage with a modified sinker plate for knitting stitches on main bed only, making ribber settings fixed throughout, and allowing for tension adjustments for each color yarn.
Methods A and B are both used in Japanese machines when each color is intended to be knit for 2 rows with color changes on the left.
Method A works on pairs of rows. If the pattern does not consist of identical pairs of rows there are likely to be yarn error messages that resolve when the design is lengthened in height X2.
The original triangle elongated to 8X16 
If pngs are created outside the program, they may be doubled in length unless the repeat is designed that way. 
The associated menu options in Dak when the plan is to work in double jacquard 
How the different jacquard setups process the specific repeats:
Method B creates the same separation as the default built-in KRC one in Japanese electronics. If knitting DBJ it may be used with DAK if the pattern is downloaded as fair isle but the machine will then need to be set for dbj. If additional colors are used, pairs of rows will follow a single pass for color1. The print preview templates, if generated within the stitch count restriction for use on punchcards, may be used as guides for punching the required holes, this would be the card for that 8X8 triangle repeat, a tad shy of the recommended 36 rows, 
Passap card reader techniques saved from long ago experiments. 
Other separation methods in the Passap are handled by the console with the entry of specific knitting technique numbers.
That said, the DAK color separation is applicable for printing reader templates if still using Passap E6 reader cards or punching for the Duo with Deco.
Method C see the top of the post
Method D separates each color into a separate reader card and is used to download to the Silver Reed PEI or the Passap E6, appears to use superimposing of layers, and matches method 4 in my post.
Method E is suitable for machines with a color changer on each side, like the Brother CK 35. It works on pairs of rows and separates each row into a pass with each color. A 3-color jacquard would have six passes with colors separated as follows: 
Method F is a Half-Milano separation. Each pattern row is separated into a pair of passes for each color, but the second row for each color has no patterning, so the ribber stitches only knit as the carriage returns to the left side, a possible way of creating repeats for drop stitch lace on Brother machines. 
The elongated triangle template was split into 2 pages for viewing, they are combined in this image 
This may be the associated Passap Reader technique, but I have no way to test it 
Processing the template using numbers: a table is created twice the length of the 8X16 triangle repeat, followed by hiding the 32 odd-numbered rows, positioned in front of the scaled punchcard template, stitch markings are traced 
the rows are then unhidden, the repeat is checked, matched here to the F jacquard separation in Dak
The numbers table is processed in Gimp to obtain the png for knitting the now 24X64 pattern 
Proof of concept swatches: the long stitch in 2 colors, 
and the pattern executed as a tubular FI knit: I had yarn issues, hence the dropped stitches. Both swatches were knit to approximately the same point in the pattern repeats, there are obvious quality differences in width and length. In tubular knits, there are differences in the width and height of the knit on each side. The front is a slip stitch with floats, drawing the fabric in, while the ribber knits every stitch every other row. With a good choice of yarn and pattern, loosening the tension on the top bed may ease this problem. As often happens, casting on and binding off need special considerations ie to allow for any fabric stretch when off the machine or to leave a tubular knit open at either or both ends if that is the goal. More info on tubular knits including on Passap
DAK has been a purchase made out of curiosity, and my use of it has been very limited since my designing needs are met by using other programs that are free to users and generate and accept files in multiple formats, while the Brother Knitleader or even simple use of the magic formula solves knitting any desired shape in any gauge.
That said, if one can generate the templates produced in DAK, the screengrab of the result may be used to generate a PNG with ArahPaint using the weave-from-grid feature that is then knit-ready on any electronic machine able to accept downloads. The method is far quicker than using Numbers and Gimp. 
DAK lace module 2, template use, other software
I am taking a break from lace, the two posts so far on using the module reflect my own experiences outside the program’s environment. The latter will continue to be the focus of my future posts when exploring the use of the software, with testing specifically aimed at adapting or using any of the Stitch designer features and output on Brother knitting machines.
Almost a decade ago I had a temporary leaf lace obsession, and it appears to have resurfaced. This pattern was offered in a Japanese machine knitting magazine, with no accompanying MK repeat. When transferring stitches by hand it is possible to move multiple stitches within a single row as well as to move stitches in opposite directions within the same row, making the published repeat executable 
When automating the repeat edits are possible and very easy using the lace module, these first drafts were created in Numbers, 
I have to admit the first time I tried to knit both the associated png, mirrored and not, I experienced patterning errors. Whether due to operator fatigue, static, or any other possible cause, on a different day both designs knit successfully, and my appreciation of the module is growing steadily. The results for this, a complex shape, are quick and awesome when compared to the amount of time it would take to draft the pattern outside the program.
The design process, beginning with Dak: in this instance, the lace tool was used with what I will call the drag and stop method, initially on the fabric texture using the smart symbols. 
At any time during the drawing process, several image view options are available and may be changed back and forth by deselecting features in this menu
An stp was created, the template is marked 74 rows in height, filled in as the stp was generated, right side facing 
Numbers and Gimp reduced the template to a png 14 stitches wide by 52 rows long, needed to be mirrored using the number one button on the 930 for successful knitting, 
matches the original illustration. Dak makes slight modifications very easy. The untested brick repeat, 28X104, developed using Arah followed by its png

comparing the initial three knit results for differences, the samples were knit using the same yarn at the same tension 
A test for the second brick repeat, here visualizing results with a screengrab of the stp. 
The test swatch is for a single repeat width, the initial yarn used ran out, hence the color change, the second yarn was thinner and broke, but there is enough to get a sense as to how the overall alignment of the knit shapes will appear, including that horizontal chevron between the shifting leaves. The png required mirroring when used on the 930. 
I became curious about reverse engineering from punchcard to an stp file: my first choice was of a “straightforward” but slow to knit pattern, 34 LC passes are made before any knitting rows follow. Ayab users have access to a huge library of knit-ready pngs, this was one, it also happens to be 24 stitches wide, so suitable for punchcard users. The published repeat as given is shown on the left, mirrored for use on my 930, left and right transfers are then marked in red and green respectively to check transfer placements. The right half of the image is then copied and dropped down a single row reaching the necessary configuration for Dak, allowing for the stp to be created. 
deselecting yarn colors in Dak provides a clearer view of transfers 
the 24X36 original png: 
A proof of concept swatch: the yarn was too thin for the many transfers and broke, so on the right, there are fewer stitches than initially planned. At the bottom there is a single instance of 2 rows knit after all the transfers, there are 6 rows knit after each transfer series in the remainder of the swatch. Color changes could be added in multiple places to interact with the wavy shapes 
The template for the stp as first attempted is something quite different but would work if the pairs of blank rows between pairs of transfers are eliminated over its length except at the very top
it would need to be drawn eliminating the pairs of blank rows between transfers to match the original repeat because all those carriage passes are consecutive. Drafts with no blank rows between alternating transfers are not accepted by the program and ruled out in any template preview as well. 
The complexity of working with a “simple” repeat: over the years I accumulated a notebook full of copies from Japanese magazine pages with what I believed to offer interesting potential, this repeat happened to be one. The markings for the knit rows on the right, and the two blank rows at the bottom identify it as suitable for Studio punchcard machines, and it would appear to be easy to translate for knitting on Brother thanks to those 2 blank rows between transfer cell markings. 
Developing the Brother repeat in Numbers for beginning with transfers to the left. The repeat is recognizable as a mesh variant, more information for mesh design repeats may be found in the post, the lace carriage is used for 2 passes, and then for 4 passes alternately 
the repeat on the right was created in Gimp. 
The 12X18 png 
was mirrored for use on my 930, some cables were added. A 1X1 crossing in the thin yarn used in the sample would have been nearly invisible. The placement, in this case, is at the top of the full repeat, after the first knit row before returning to transfers for design row 1, an easy way to track the hand technique. The 2X2 crossing used might need help with definition and placement in a wider vertical knit strip 
Creating the stp: the size of the png was used to create the image file, which required cropping, in Dak this would be the menu language after activating the proper tools. the stp size is 12X16, 
The template generated for a Brother punchcard machine illustrates the problems and some of the confusion if the template repeat is used for actual knitting, especially on the punchcard machines. Drawing the eyelet and dragging the mouse one cell to the left is the intuitive way to draw for transfers to the left. The symbols appear to be right-side facing by default and if they are in turn mirrored by the program prior to saving, when the templates are generated, the intent for use of the design would match. The numbers on the left are in the punchcard template, adjusted by cropping the two extra rows in the Brother electronic template by the software, do not reflect the actual design row numbers. The starting row is wrong for the Brother lace carriage operation from the left to produce the first row transfers to the left in actual knitting. As far as determining sequences for knit row placement, that is left up to the punchcard knitter’s experimentation. The minimum repeat for a punchcard to roll continuously is 36 rows, that fact needs to be considered if punching cards. The repeat shift for the first transfers to happen toward the left is illustrated on the right. 
As initially given, with the lace carriage starting on the left, the first transfer row would be to the right. In many cases, this may not matter, but in this instance, where the knit rows happen after 2 or 4 LC passes respectively, the template offers another instance of the fact that the knitter using it needs to have previous understanding and experience in creating the particular stitch type. This version does not have an accompanying swatch. 
Analyzing the electronic template for interactive knitting: it is correct in marking rows for LC operation from the left with the first transfer row made to the right, matching the above chart. 
The LC operation is continuous 
Eliminating the rows marked with red would yield a workable punchcard repeat, with loss of the cues for the proper sequence for LC passes.
In this case, it would be best to redraw the adjusted electronic repeat prior to punching any holes.
Getting that first row to transfer to the left can be achieved by mirroring the first stp draft, using the second selection, 
the resulting electronic template yields the repeat with transfers in the direction intended, as seen in the proof of concept swatch and its repeat 
For good measure, the repeat is also drawn as stitches and produced the punchcard template with a first blank row identical to that generated when using symbols 
Using the pencil tool to draw the transfers differently resulted in a series of error alerts, so not an option.
For Brother knitters mirroring the self-drawn stp and altering the electronic template may be the way to go. Also, be alert that Brother and Toyota punchcard knitters cannot knit interactively because the interactive knit rows present in the mylars cannot be present in the punchcards, a fact that is acknowledged by the software company nearing the end of the content on the lace module. No mention is made of the fact that for successful knitting the knit carriage on Brother needs to be set to KCI or II for the pattern to advance properly during interactive knitting and that those rows need to be omitted if entering the pattern on a mylar sheet or are using the repeat for download to a machine outside the DAK environment and you prefer not to have the knit carriage selecting needles as well as the lace carriage.
In summary, the information on the tool presented in the manual for the module:
DAK lace module 1, template use, other software
Working with lace designs: lace poses interesting challenges in machine knitting. The name is associated with a variety of fabrics, but transfer lace is the specific topic for the moment.
Reminders with respect to transfer lace knitting:
in Studio simple lace the transfers and knitting occur for each row of the design with each pass of the carriage
transfer lace patterns in Studio km begin with 2 blank rows and end with markings for transfers
Brother transfer lace begins with needle selection markings for transfers and ends with two blank rows. The knit carriage does not advance patterning rows unless the change knob is used to select needles as well.
Hand knitting charts typically illustrate the knit side, while in machine knitting the knitter is working looking at the purl side, so if charting for duplicating the same transfers, the HK pattern requires mirroring
The Brother lace carriages usually operate from the left, and Toyota from the right
Some download programs automatically flip patterns horizontally, great if you are working with texts in most cases, but a consideration if you wish to control the direction of other stitch-type formations, and lace patterns drawn in the program may need to be flipped as well in order to knit properly on Brother with the lace carriage operating from the left side
When I design, out of habit, I try if possible to work with repeats suitable for punchcard machines as well.
Facebook members who participate in machine knitting forums have access to the information generously shared by members. Sheila West published a video on drawing lace repeats on a DAK knit stitch symbols ground as opposed to the more traditional charting using lace symbols on a blank design grid, and there is also an associated downloadable PDF.
Softbyte support has been responsive and at times helpful in communicating with me, and reviewing issues I encountered.
I prefer to download manuals for software when the option is available making it possible to review them when not running the program. In my enthusiasm to do so, it appears I downloaded the manual version offered in the last tab, which happens to be for section 5, graphic design studio, which by default was not helpful in using the lace module. When I initially looked for help, the information that became available was for the wrong module, 5. In using the program on Oct 21 I have not been able to replicate that issue when opening other modules.
When the program is first installed, the manuals are listed in a series of tabs, ending with that for section 5. For Stitch Designer, choose section 3, the manual appears and a way to download the associated PDF is also provided. There are 5 help files and 5 manual files. They don’t interact at all and work completely independently from each other, can be opened from DesignaKnit or from a file browser window.

Update: 
The lace module is an extremely attractive solution for speeding up the lace design process whether from published charts or DIY. The left mouse button is used to draw as usual, but the right mouse button is used when drawing shared transfers in fine lace on Brother, or simple lace in Studio km.
My initial experiment and observations:
each time the program opens a new session, the normal drawing pattern appears. Selecting the Lace tool icon in the left menu bar will change the default palette to include the necessary symbols. In working with stitch symbols this is the range of available, 
It is possible to show any repeat tiled as well. For lace the number of stitches and rows should be close to those required by the design, its overall size may be trimmed if needed when the design is completed.
The left mouse is used to apply the symbols, I have read the right mouse has a different function and is used to draw shared stitches in Brother fine lace or in filling in simple lace designs for Studio machine models.
To select the lace mode simply click on the small icon on the left menu bar, a grey border on its left and the upper edge will indicate it is active, the palette and cursor will change. 
The designer may enter patterns on this view as well, but I prefer to work with symbols
It is best to begin testing with a small repeat when exploring new techniques, find his format easier to use than drawing on “stitches”. There are several options for the canvas ground color, the default is in blue. As a first step, saved as an stp, Dak opened my saved file as pictured in this view. 
Wrong approach: The pencil tool must be active to continue to draw, left mouse click to place symbol, right mouse click to erase, clicking on any symbol in any one row will call up pertinent information on its location in the repeat
Is there another way to draw symbols while working on a lace design file? use the lace tool, using the pencil tool with each type of lace symbol is not recommended
DAK row numbers do not refer to design rows, they reference row counts as would be seen in any row counter registering carriage passes
Other views for the repeat: as yarn colors 
and as stitch symbol palette 
If a symbol is missing from the drawing, the program alerts the knitter to the error. Here there are no eyelets represented. 
There was no warning for the error in the last row of the test stp, where in the last row two stitches were being moved in opposite directions on the same row. If the content is considered accurate, this window will appear, the safe button will be highlighted, click OK 
I found this lack of warning for some errors in later designs as well, it is a topic under review by the developer. When choosing machine knitting options lace is not offered as one, fair isle is used 
To print a template for use on another machine the stp file may not be used for copying to clipboard and converting to stitches in another program. In the print menu, saves are possible for templates akin to graph paper references for working further on both electronic and punchcard machines. For the electronic printout, the choice of the machine appears to need to be set to 950i
wrong side facing is chosen for the purl side view. 
Stitch pattern print previews, using default settings for layout:
the stitch pattern picture was basically a numbered graph paper image with no content, pattern text, and not particularly useful
other previews:
the suggested electronic repeat: 
The templates for electronic models have 4 rows between transfer sequences rather than 2 as is usual for Brother. They are needed for interactive knitting where the KC passes are represented onscreen as well, Dak knitters likely set the knit carriage change knob to select needles on KCI or KCII.
For punchcard end-use, change the machine setting for print preview to Brother/Knitking standard punchcard, and click ok. When you choose Fair Isle, DAK will reverse your design and that may mean that there will be two eyelets side by side or double stitches transferring because the transfers are being made in the wrong direction. DAK will invert the pattern from left to right if it has the knit method Fair Isle or Wrong Facing. If it has the Right Facing method it won’t be flipped. The knitter still needs to sort out whether right-side facing or wrong-side facing makes any difference in their particular brand machine outside the Dak environment. The need for added mirroring for correct transfers depends on the download program ie Ayab mirrors any programmed image automatically, or the specific brand machine ie punchcard vs. electronics may behave differently. An easy test is to use the repeat on a small swatch, if side by side empty needles appear on the needle bed, the pattern needs to be reversed. Any lace designs suitable for a punchcard machine, when they are knit on my 930 require mirroring unless the png is saved mirrored horizontally in the paint program used to create it prior to download to the machine. 
the repeat:
The numbers on the left correspond to carriage passes, not design rows. While the electronic template represents the interactive kitting repeat and differentiates between rows for use of the LC and KC, leaving the KC rows unlabeled, that distinction is not made for punchcards in any way, and marked numbers are not in sequence. Published Brother punchcards contain additional symbol columns for added guidance on settings and carriage passes.
Assuming the knitter knows whether the programmed repeat will need to be mirrored or not to knit properly on their specific model knitting machine, the 24-stitch punchcard version should work on both model machines.
The numbering on this punchcard template skips 2 numbers for knit rows between transfer repeat segments as seen in the first sample, and in this later repeat, the number sequence interruptions are marked in red. In punching long cards especially, renumbering the whole would make the repeat easier to follow. 
This stp pattern was also created using the pencil tool in combination with symbols. In the print preview, there were 2 errors in the Dak printouts, the three blank rows rather than 2 in the outlined section between transfers, and transfers in 2 different directions occurring on the same row with the same carriage pass. I have no way to test whether the same issue would occur in interactive knitting using my own stp file. My repeat, drawn in Numbers on the right, is numbered in design rows. 
When choosing print, the global options allow for editing items out such as company name, date, and format by simply clicking in the associated boxes 
choices can also be made on how to represent stitch units If the plan is to create a punchcard template and the repeat is too wide, an error message appears

It is possible to save the template as a bmp of the full image. The size of the file is shown to the right of the pixel count number settings for the clipboard or bmp file, which will vary in proportion to the stitch and row count. Click on the floppy disk icon to save. 
My hack for reducing the onscreen size of the templates for screengrabs I could trace in a spreadsheet was to use a 600 mm setting for punchcards, and 350mm for electronics instead of selecting a paper size. The actual printing to scale is not an issue at the moment, but it is possible to print templates to full size, involving a bit of trial and error with individual printer settings and math.
The proof of concept swatch, knit on a Brother 930 KM, mirroring the image was not necessary, the dropped stitch was a surprise design feature when the swatch was very lightly pressed

Regrouping after a review of my pencil tool repeat by Softbyte support: the original stp has an error in it on row 11 where yours truly had eyelets being created by having the same stitches moved in opposite directions in the same row. It is interesting that I was able to save the stp without receiving an error message as seen in this instance below when the pattern was being redrawn with transfer symbols on the wrong row, 
The amended final repeat, 
in turn, produced a correct punchcard template using the print preview 
As an additional lace template test, I repeated the process on a portion of an stp file shared generously shared by a DAK FB group knitter along with photos of a completed, lovely lace sweater using it. The results are shown sideways because of the repeat length. The 950i template places four rows at the end of each lace sequence, while as seen in the published repeat of a different lace beside it, there should only be 2. The carriage passes made by the KC in traditional lace knitting though they advance the row counter, do not advance the pattern unless it is selecting needles as well, ie in trims that combine lace with the slip stitch setting. Exceptions to the 2 blank rows rule occur when the lace shape reverses direction such as in zig-zags, or when plain knit or pattern rows are planned deliberately to mix and interact with the lace design. 
Please see the previous post for more on lace charting and explanations for those in-between added pairs of rows variations. Brother knitters outside the DAK environment may use the templates as they are, but set the knit carriage for pattern selection as well on KCI or KCII.
This is another lace stp pattern built using the pencil tool method. The charted symbol diagram was published in a Japanese magazine along with its published punchcard design. There is an intentional extra row at the bottom of the repeat, making it “wrong” if the intended use is on a Brother machine as a test for how the template might handle it in the print preview. Template previews were created using the setting for Brother standard punchcard bulky or Brother 950i
Facilitating correct DIY designs, in addition to the warnings if there are missing symbols or any other problems with the design and their respective row locations, the module provides a warning about that extra row, explaining that if the generated pattern is used as is, the bottom row should be moved up or the LC should begin pattern selection from the right. 
The electronic preview continues to have a series of 4 blank rows between transfer segments. The punchcard template has 2 blank rows between each transfer segment and matches the published pattern with a 3-row exception toward the top of the card. The renderings below begin with the DAK punchcard template on the left with its confused numbering, the extra empty row at the bottom of the repeat was eliminated. The overall repeat is mirrored. It is followed by the published pattern associated with the chart, pixels are then marked for left and right transfers, followed by my amended final repeat, which when knit on the 930 required mirroring. 
Lace tool use instructions begin on page 299 of the third module user manual, Stitch designer. From the manual: when the Lace tool is clicked, lace patterns can be created by using the LMB or RMB to click and hold on the stitch cell where the eyelet needs to be, after which the mouse can be dragged in the required transfer direction and let go on the stitch that needs the corresponding decrease. Intermediate transfer stitches will be added automatically where appropriate. If the button is clicked and the stitch pattern has a method that is incompatible with lace, the warning that is shown on the right will be displayed. The Wrong side facing texture is probably the most natural choice because this is generally considered the normal method of knitting on Japanese knitting machines. Sections of Lace and Fair Isle may be used in the same stitch pattern and either Fair Isle or Wrong side facing texture are good choices when working with lace patterns.
If either of the Right / Wrong side facing texture methods is used, and there is only one color per row, it can be transparent or opaque. If there are more colors per row, the opaque color is seen as the real yarn color, while the transparent colors are regarded for memo purposes.
The lace smart symbols have an associated ‘texture’ which is used to see a representation of the finished knitting. This representation is not entirely accurate as decreases have to be shown on a single stitch cell instead of over the two adjacent cells that are affected. However, the bias of the transferred stitches, as well as the lace eyelets are well represented to give a good idea of how the stitch pattern will look when knitted.
The symbols that are specifically used for machine lace knitting are displayed with a light green background in the Symbols Organizer. 
The same repeat as above was redrawn, with that extra bottom row eliminated 
The associated template preview for the punchcard nearly matched the one that was obtained with the pencil tool chart, but had some differences: the previous image was mirrored although no dak settings were changed. As in all punchcard template numbering, the knit row numbers are skipped in the sequence on the left, so they will not match design row numbers, and the small flower motif is placed differently 
This sample was knit using the pattern drawn with the pencil tool, pre mirrored for use on the 930. The convention for lace designs is that they must contain an even number of rows, the one on the right is 47 rows, knits properly, but is suitable only for a border. Here a pair of extra rows were knit, followed by design row 1
A wider swatch
When attempting to use this repeat for a continuous one, unless the total number of rows is an even number, the second repeat will reverse the direction of the transfers, resulting in mispatterning and multiple side-by-side empty needles. Changing the total repeat to 48 rows by adding another blank row places all transfers properly. The 12X48 png
Adding extra knit rows at the top of the repeat ie. 6 or 8 may make the alignment of the 2 shapes to each other more pleasant.
The challenges in DIY lace patterning are many.
The same design was redrawn using only the lace tools. The appearance was the same as in the previous draft, the print preview template was two rows shorter, 46 rows long, and no longer mirrored, with the flower shape slightly lower than in the other sample, it is shown here alongside the Gimp png draft for exporting the png used in the samples. 
Knit in continuous pattern with 6 knit rows added before restarting with pattern row 1 with LC on the left 
A half drop repeat is also possible. To achieve this test of a repeat drawn in a paint program, I knit 2 rows after the last “flower” eyelet and had to flip the repeat horizontally before continuing for the top half of the repeat, producing a very different look. 
There is a transfer error in the knit swatch on the right where I “repaired” a dropped stitch. Edits would be needed if one is determined to make this pattern automated as a continuous design.
Options for manipulating stitch designs in dak appear to be the following. Interested in developing an automated brick repeat for the above design, this was produced outside dak as a guideline for entering the symbols in stitch designer 
Using the lace tool, the areas marked in red highlight cells where wrong symbols for stitches in those areas were initially created using the lace tool. Use of the pencil tool was necessary to replace the incorrect symbols. The stp was saved with no error warning, but the resulting repeat was identical to my self-drawn one with the top half of the bricks knitting in the wrong direction resulting in mispatterning and double eyelets.
Saved stp files may be opened and further edited using either or both the lace tool and the pencil tool.
With respect to the use of the pencil tool, from the manual: “It is possible to place lace symbols onto the stitch pattern manually by activating the Pencil tool, then selecting and placing each symbol where required. However, this can easily lead to errors as the placement of each symbol needs to be well understood.
The “Check once for color changes etc.” option in the dialog can be clicked after which dak will either display “No errors found” or it will display error messages such as the ones shown here.
Clicking “OK” returns the program to the workspace where errors may be corrected. DesignaKnit does not mark the pattern when these errors occur. After correcting, “Check” can be run again to ensure all errors have been eliminated. Using the Lace tool to create lace will greatly diminish the chance of errors.”
I have encountered instances where no error messages were received, the stp was saved successfully for supposed knitting, have been told there are edits and future updates underway for both version 8 and version 9.
the right mouse button is used when drawing fine lace designs, which is not part of my present explorations
In theory, the Lace tool will:
insert the eyelet, transfer and decrease symbols in the direction of the drawing
insert a double decrease symbol where the lace transfers occur onto a single stitch from opposite directions
prevent the placement of eyelets on adjacent stitches within the same row
warn of invalid lace sequences when saving or checking the pattern
remove the eyelet, its matching decreases, and any transfers in that sequence with a single click of an eyelet symbol with either the right or left mouse buttons
Brother knitters need to keep this in mind when using the lace pattern in the dark environment, the knit carriage will need to be selecting needles as well.
If using the templates to generate patterns for use with other download programs, the traditional use for Brother lace and punchcard machines is to have the knit carriage not selecting needles. To use the given template for the electronic in that manner, 2 out of the four blank rows between each series of transfers may be eliminated and the pattern from the electronic template if within the punchcard repeat restrictions, may be used on punchcards as well. Having plain knit rows not selecting, in my experience, makes for easier unraveling and returning to an all-knit row when rows need to be unraveled to correct errors or knitting falls off the machine.
All punchcard templates keep the number sequencing for the electronic repeats, removing the extra interactive knitting rows and their numbers from the electronic template, reducing the repeat to design rows, which results in the numbering sequence on the left not matching the actual total number of rows in the repeat, making it ineffective if following those numbers when punching cards.
Making things work: the dak repeat for the brick arrangement, there are single blank rows before selection for the shifted pattern begins, 
my edit in a spreadsheet, the yellow cells mark rows missing in order to get the lace carriage back to the left side before the next pair of all knit rows. 
The full repeat was trimmed to 12 stitches in width, and 48 rows in height, 
opened in ArahPaint, and drawn in brick repeat, shifting the top by 6 cells. The green lines mark the original single blank rows followed by the pairs of added blank rows with no markings, the needed corrections 
the Arah image was saved as a png, knit on my 930 using img2 track, and mirroring
The proof of concept swatch for the now fully automated pattern 
When a repeat is sorted out it is easily modified to create other variations. Here the small flower shape is eliminated, as well as the first transfer sequence to produce stacking triangular shapes. The repeat is now 10 stitches wide by 28 rows high, so suitable only for electronics. 
The swatch was lightly pressed, prior to that, there was actually an interesting 3D quality which can be common to many unblocked lace patterns. If the knitter wants to retain that quality, the quandary is then encountered as to whether one also may want the piece to lie flat, particularly at the sides and the top.
The above repeat was mirrored for use on the 930. With lace as with other fabrics, the repeat may be tiled and programmed to the width of your knitting, here for use in a 30-stitch swatch. While in other fabrics a plain knit border may be added by placing black cell vertical cells on each side of the wide repeats, this cannot be done in lace, because those selected needles will attempt to transfer multiple needles in a single pass, which is not possible. Brother offers edge-stitch plastic cams to help with that. The cast-on in this instance is a provisional one, with several rows knit prior to beginning the use of the lace carriage.
