QTR-Quadtone RIP

This helps quite a lot, Mike. I do have the K7 inks loaded correctly and have been using them successfully for several years, both at home and at the institution where I teach. The K7 / Photo Rag profiles that come along with QTR produce beautiful prints, especially with the Special Edition inks.

However, I would like to learn how to create profiles, at least for my own work. Sounds like I need to work with more generic inksets. I'm thinking of Eboni 6.

Thanks for pointing me in the right direction.

Seems like a good way to learn, since a profile for that ink/printer/paper combo comes bundled with QTR, and I can ultimately compare my profile with the bundled one. Good theory, at least.

However, in the K7 inkset I am using (Special Edition) channel #5 is far more dense than #4 or even #3. Effectively, there is no crossover with the previous channel. All of the other channels do have a crossover limit.

I use their K7 Special Edition inks and use their profile that come with QTR.  With the 4880 printer you can use any of the profiles for Epson printers in the series with  x880 designation.
