QTR-Quadtone RIP

I saw micro lines w/ P800 and 2880dpi until Roy updated to super microweave in 2.7.8 (thank you Roy). This was for both paper and negs on all new sure colors and all small format printers (P400-P800, not wide formats). The P800 uses software weave and the 38xx printers are hardware weave (in the printers).  Dither is a different thing than weave and is still: ordered.

I have found Eventone Hybrid dither (part of 5.xx gutenprint code) to work better for digital negatives and therefore built out an independent driver for this type of work with the help of a few Gutenprint developers and my own rudimentary coding skills. . . but it is private beta for now and ideally I’d like to see QTR incorporate this update although I fully understand that this would be a massive undertaking to re-structure QTR from it’s older code-base to a updated base with the improved dithers . . . .

Related to topic at hand: P800 is a different printer (nozzle density, etc) than it’s older brothers and sisters.

I’m working on getting third party chips for this printer over the next weeks (right now a decoder board is the solution for third party ink systems on the P800).

Best regards all,
Walker
