Hi Felix, Kerik is really good at this stuff, but if you want to try I just posted by base profile in my last post to David. I can give you one with a Gray Curve if you want, but the papers I made them for are quite different than Platine or any of the papers commonly used for alt-process printing. Even the 2 papers I made final profiles for were different enough from each other that each required its own Gray Curve. You would most likely need to make your own Gray Curve from scratch anyhow.

You did not respond. The offer still stands. 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. >> >> At the very least, trying this might help to determine whether the cause of your problem lies with the profile or if it is something else. >> >> Cheers, >> Keith >> >> Keith Schreiber >> jkschreiber.com <http://jkschreiber.com/> >> >> >> >> >>> On Nov 21, 2016, at 6:54 AM, daimone@... <mailto:daimone@...> [QuadtoneRIP] <QuadtoneRIP@yahoogroups.com <mailto:QuadtoneRIP@yahoogroups.com>> wrote: >>> >>> Does anyone have a clue why I'm getting these patterns with QTR and the Epson P800? >>> >>> >>> I've gone through nozzle checks and print head alignment, no different.
