QTR-Quadtone RIP

Hi Keith,

I have been printing dig negs for printing on Arches, would love to try your curves and share the results.
I have no dithering or any problems with what I use right now, but I would be interested to see the differences.

I am currently using curves and profile Kerik Kourik helped me develop for my P800.

-Thank You,
-Felix

It is a profile that I made for a friend who is printing Pd on very thin translucent Japanese washi with negs made on a P800. I can send it to you with and/or without a GrayCurve, though without would probably be more suitable since you would need to customize the GrayCurve anyhow. I have seen her negatives and they are beautiful with no sign of dithering or any kind of pattern and a Dmax of around 3.2 which is way more than OEM inks produce on my 3880.
