QTR-Quadtone RIP

Dear Peter.

Some reading: https://piezography.com/epson-pro-4800-4880-installation/ <https://piezography.com/epson-pro-4800-4880-installation/>
The curves (you’ll need K6 curves from the Curves-HD folder) and manual: https://piezography.com/downloads/piezography-community-edition <https://piezography.com/downloads/piezography-community-edition>

In the manual check out the advanced topics section. You’ll need to swap the Y (shade 7) ink with the ink from your blocked channel and do the same in the .quads from the k6 curve (using a text editor).  The K6 curves allow for printing with only 6 shades + gloss optimizer.

Best,
Walker
