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, except 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 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 before 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 

A large variety of pleats may be knit on the single bed as well, one being shadow pleats. The resulting knits also need to be gathered on one of the 2 edges in items like skirts at waistlines, and the number of knit rows needed for the volume required can be daunting and a large commitment of time if not effort.
Both yarns used are wool, a yarn that has memory and spring-back. In the potential fold rows, the red color was replaced with a thin ply with the same fiber content. The first folds were knit in an *8 with thin, 14 with thick, 8 with thin** color sequence. Watching the knit as it progressed showed the thicker fair isle areas folding inward, with the thinner areas folding outward. The remainder of the swatch used a 4 thin, 8 thick sequence. The knit was steamed and pressed, the folds are soft but permanently present with the lower edge of the piece lying quite flat after a considerable amount of time. 

The blocking saga: I do own blocking pins but honestly have only used them in demos, and on rare occasions such as this, or to cut them down when I needed a fast replacement for a ribber cast on comb lost wire.


after steaming and pressing 

Trying for a bit more detail, there is a see/peek-through quality.
At first, I thought it might be a version of the stitch using 3 colors, but later, looking again, I came to believe it to be a 2 color 
I wanted to add solid color drop-stitch stripes, the solution being to add all black rows. Every needle will select every row in those areas, colors are changed every two rows, creating the desired effect when the corresponding stitches are dropped.
A visual summary with an added color change column and row numbers with rows on which dropping all loops can occur marked with different color numbers. In this case, the ground is in the dark color, the shape in the lighter one.
Determining whether the shape or the ground stripes knit the dark color is simply done by beginning the first all knit rows with the dark color or the light.
but I would like to have stripes in the solid lighter colors as opposed to 2, 


Here some of the peek-through quality of the fabric is shown again. When any fabric is gathered sideways, it is likely the repeat will appear narrower and longer.
Using a 16/2 cotton at nearly the same tension produces a fabric that is even sheerer. 
And now those solid stripes in 2 rows knit are really bothering me, thinking they should be switched to only one row of loops, making the original repeat without those added black rows the better repeat?
A potential use is for the thinner knit is for it to be used as a layer over a different pattern or the same design as seen here, in the thicker yarn 
seeking a rounder, smaller donut shape:
The red is a thicker yarn than the pale yellow, the fabric had an interesting slight curl evocative of shadow pleats. Other possible changes include the elimination of the top and bottom row in the original design.


The repeats for designs may be self-separated to suit.
Three variations of the final png files are shared
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.





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
The elongated stitches allow objects behind them to peek through 
Here the goal is to use the img2 track separation, maintaining the same color change rotation in each piece.

The tiled potential appearance as a dbj fabric:
In the first sample three carriages are used:
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.


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.

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.

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.


The image is processed as for the previous separation, the final png is exported. Open the saved in Gimp.
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.

Knitting process on a 930 using img2track:
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.
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.

It is possible to work some repeats on some machines with the ribber also set to tuck both ways with EON needle selection.
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 20X20 repeat as a BW png
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.
The final image double length, showing the difference between the separation using the template, and that using layers as in Claudia’s video, which appears different but is actually the same repeat, color reversed.

Creating blistered surfaces the easy way, leaf pattern variations: poly-cotton and raffia on the bottom, fishing line as the second yarn line on top. I have found the line for 6lb or fewer works best. The knit is flat.
Felted rayon chainette and wool; when the main color is wool and the rayon renders the floats, there is minimal blistering.
The result of reversing the yarn positions creates more bubbling.
Here, elastic is used as the second color in the thread lace setting. 

The yarn positions in two-color single-pass knitting remain fixed in their relationship to punched holes. In fair isle patterning, the back feeder, usually labeled A, knits the ground on non-selected needles in the B position. The yarn (red) in the forward, B feeder, knits the stitches on needles selected to the D position, which correspond to punched holes or black squares in a mylar, black pixels in a computer file for download. In thread lace, the back A position yarn knits both yarns together, while the forward B position yarn, red thread, knits the forward yarn/color, with the other yarn creating the single set of floats behind it.

In addition, large thin fabric shapes can be stiffened over enclosures to create permanent effects in sculptural pieces.







A comparison to the mirrored original inspiration, likely knit in thicker yarns
The knitting process: with any textured or very lacy knits casting on and binding off require special consideration.
Read the first row of the pattern, cam set to KC1 to ensure end stitches are knit when patterning occurs only on the top bed.

The repeat is 8X8 and the above movement can be seen in the purl view.
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. 




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. 

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. 
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, 
It is possible to use the repeat working 1 X 2 stitch crossings for a very different look.
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. 

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.


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.
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 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.
An attempt at a larger swatch using 1X1 ribs:

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 

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.
The number of rows between crossings can vary. When the crossing row is reached:

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 
There appears to be enough slack produced in the formation of stitches between beds to make the planned crossings possible.
From a Brother pub, small crossings for a smocked effect 

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 
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 

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.


then click on the shape or drag one onto the sheet to add it.




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 
Right-click on the final shape, copy it, and paste it several times on the sheet away from the table.
To use the shape, left-click on it, drag it into the desired position.

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
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.

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
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
