Anyone interested in a few projects?

Hey all, In 2016 and 17 (forever ago it seems) my company paid Solomon to make some custom LUT code inside Gutenprint for Epson-printers. We got it working as an in-house implementation for some experimental monochrome printing that we do at Cone Editions Press here in Vermont. To that end: 1. I’m wondering if anyone would be interested in a bit more paid (FOSS) work to actually get the LUT code and workflow validated and working in the current Gutenprint master branch. Robert did some initial LUT-work there but I was never able to implement the code properly because I’m just kinda not smart enough. I think it’s a useful addition to be able to do externally linearized LUTs per channel or color . . . 2. I’m wondering if anyone is interested in some paid work to do this LUT work for Canon. If we can do the LUT work inside Gutenprint then maybe someone can develop a proper open source workflow for monochrome ink printing on the Canon platform. 3. Finally, DITHER. All the dithers in Gutenprint are channel unaware meaning a dot placement on one channel (take Cyan) is not aware of the intersecting lighter channel (Light Cyan) dot placement creating randomized double drop overlaps. This is generally fine for color printing (CMYK) but does create unnecessary dots and has always been a problem for multichannel monochrome printing. A much higher-quality way to print would be to calculate randomized dither points only inside the drop voids of adjacent darker or lighter channels of the same color. This would minimize ink bleed, maximize total ink limit, maximize gamut, and minimize noise, and increase real-world resolution of fine details. What are your thoughts on that code? Is it needed or not really? Was this part of the never-finished “Even Better Dither? Ideally the Ordered New would be channel-aware . . .
