Inkjet-based 3D printing - Frecuency Modulation algorithms

Some Frecuency Modulation (FM) or Stochastic screens method are used when printing images on an inkjet printer. This method uses all the same size dots (same drop sizes in my case), but varies the spacing, or frequency of the dots to give the illusion of continuous tone. I'm looking for an algorithm to, using a FM method, build differents colors using 4 inkjets CMYK channels. I'd appreciate some references or information about it.

I'd expect you'd operate this pretty much like a stepper motor: send a pulse whenever it's time to put a drop.

To convert images or vector based formats to pixels, GhostScript is pretty good. It allows to process data in a queue, without intermediate files (which could become huge).

Good point.
Thanks!
