QTR-Quadtone RIP

Hi Roy,

thx. for your response. I checked the nozzles and adjusted print head
but could get no change for better. Using the 1440x1440 super or 2880
resolution didn't also correct the problem. As the printer works
correcly with other software using the original Epson driver for me it
seems to be a issue with the software. Do you see any changes to get
it fixed?
I found one way  to avoid the bandig: letting a margin of ca. 1.5-2cm.
But that not realy a good solution.

Thx. & Rgds.
