Basic workflow is using water soluble dyes inkjet printed onto waterproof transparency film (used in screen printing) and then transferring to mordant treated gelatin. You would use registration and 3 color separations like the traditional process. Anyone try this already? I don't know much about color printing so please poke holes in my idea if you do.
I've not tried it, but it might work. What I don't know is whether the dye/mordant system needs certain chemical compatibility and whether inkjet dyes would be suitable for such a system.
Moreover, I wonder why you'd bother with all this instead of just printing on the gelatin directly? I did some brief testing with that a few years ago and the results were quite promising provided the paper is nice and flat. https://tinker.koraks.nl/photography/easy-way-out-inkjet-on-diy-papers/
I'm thinking about using actual/historic dye transfer dyes in refillable cartridges. I don't think that there is any way that inkjet on the surface is going to look the same as dye drawn into gelatin where it mixes with other colors. It's not a halftone effect.
If you inkjet print the original, then that's already halftone. To get rid of the dots, you could allow them to bleed during transfer - buf if you're going to do that, why not use a medium that allows for more bleed in the first place? And then we're back at my idea of printing directly onto gelatin-sized paper, which is more straightforward.

Gotta fade test the dyes. Pigment inkjet are outstanding for fade resistance. Inkjet dyes are terrible. At least the ones I tested a few years ago. I have not kept up with it, so you check it out.

Photo was cut into 2 pieces. One part was put in the sun for 6 months, the other piece was put in dark storage.
