Digital BW, The Print

Carl,

I was using 1440x1440 Highest Quality. I tried printing the calibration
chart again with 1440x720 HQ, but same result... The only other thing I
can imagine is that there is still some sort of unwanted profiling with
the postscript driver I'm using in Windows to print to the Linux
machine. I make sure to use 'Don't color manage this document' when I
open the chart in Photoshop, and print using 'Same as source'.

I would try to print directly from linux to compare, but for some reason
that doesn't work. I just get 'No pages found'.

Actually the prints look very good when I use GRAY_OVERLAP=60, the only
issue I have with that is some slight dotting from the LC in the
highlights. If I could just move the endpoint of the LC curve a bit
inwards everything would be perfect.
