The post Single bed tuck and slip stitch fabrics 1 reviews some of the differences between the two stitch types, and the characteristics of appropriate pattern repeats.
Single bed tuck and slip stitch fabrics 2: adding color introduces visualization and samples, executing both with frequent color changes while Visualizing maze or mosaic potential from tuck or slip stitch repeats begins with designs that are already developed/published and constructs the visualization of the potential results with frequent color changes.
DIY repeats bring together approaches and ideas developed over time.
A color separations post published more than a decade ago, first looked at achieving this design repeat using Excel, 
and the topic was revisited this year in Revisiting old color separations, testing present software methods, leading to present testing of the concept using the same software tools to produce a tuck knit pattern with alternating color shapes while observing the conventional tuck stitch rules.
In this case, if each color is to knit tucks for 2 rows, then it must be represented by cell units that are formed in single width, and 2 rows in height/ across each pair of rows.
Using only BW pixels, the process began with a 13X26 PNG
doubled in height to 13X52, 
redrawn on a larger canvas, to 14X56
using ArahPaint drawn in half-drop repeat, offset by 28 or by 1/2 using the pull-down choice. 
28X56
Relatively small designs are easy to manage.
A first alternative: in one half of the repeat, erase or fill in with white the first 2 rows of black squares in the design, while in the second half of the repeat, do so with rows 3 and 4,
and test alignment by drawing the design in repeat.
Visualizing placement of tuck stitches on striped ground:
1. the original repeat
2. the revised repeat
3. the striped ground in any chosen colors
4. #2 with white color to alpha copied and pasted on #3
5. in any final knit when programming the design, the black cells in #4 need to be white for tuck stitches, and the ground a solid black.
Both #4 and #5 prove that held stitches/tuck loops in both colors are not represented together on any pair of rows. 
A second alternative uses ArahPaint on half the repeat at a time to allow for the 2-row upward shift between designs
1. adjust the grid width to 14, providing a vertical guide along the vertical midline
2. fill a 14X56 new image with a first 4-row brush
3. copy and paste it on #1 right, after rendering the green color in 4 transparent
5. a new 14X56 image filled with a second 4X4 brush
6. copy and paste it on #4 left, after rendering the magenta color in 4 transparent
7. the final repeat
The test knit repeat, 28X56, is centered in a 60X56 canvas with an added two-stitch vertical border on each side; end needle selection is canceled. 
The repeat may be used as is. To meet tuck rules, it then must be color reversed using the machine’s appropriate button after downloading, or color reverse the PNG before saving, and use that as is. 
The change to the second lighter color yarn was made to facilitate the ability to visually check the proper formation of stitches on the purl side during the test knitting of the swatch. 
The repeat may be reduced for use in punchcard models.
and is drawn in repeat to obtain the brick configuration on the left, and then the software tool is used to find the single 24X48 repeat on its right.
The colored chart visualizes the placement of the tuck loops on a 2-color striped ground.
Punchcard knitters may mark the black cells and follow with punching all other squares, as indicated by the black cells in the chart on the far right.

and after it. 
It is possible to use the punchcard reader to repeat each row twice. The 24X24 version of the separated repeat,
however, would need to be punched twice to accommodate the length necessary for the card to roll properly continuously, so not labor-saving.
Punching as required without added adjustments, such as using elongation, can make it easier to correct any errors during knitting.
Exploring the appearance of a smaller repeat by comparing results using the same yarns:
16X24 
color reversed and tested on 48 stitches, 48X48 PNG
The repeat may be made usable for a punch card machine by spacing the design to 12X24 stitch vertical segments and punching the white ground. 
The addition of a few pixels forms continuous shapes. 
The design drawn in repeat and color reversed for test knitting on the 930, 48X48 pixels, 
results in appearance and movement with a change in colorway, with more 3D texture than appears in the images.
