QTR-Quadtone RIP

I am not sure about the commands you would use for the MAC, but in the
windows GUI, there is a button for each ink called 'curve.' Clicking on
that button brings up another window. The tab 'point list' allows for 50
points. I have two columns in excel (x and y) points. I just highlight both
columns and all 50 points and 'copy' them, then on the 'point list' window I
click 'paste points.'
The process is repeated for the other inks.

I don't know if that is helpful at all since your on the mac though.
