I recently upgraded QTR to 2.7.10 for MacOS Catalina. Installed Quad-3880-Pro from piezography curves folder. Opened Print Tool. Setup QTR in calibration mode. Went to print a 8 channel ink separation file. Ink positions 1 - 3 printed normally but ink positions 4 - 8 “flooded” the paper with ink. See attached photo:
The same thing happens when I tried to print the QTR 8-ink purge.tif file
I am able to run a nozzle check using the epson printer utility without issue.
