Re: Struggling with Dmax

2007-03-27 by Jeff Randall

When you print the QTR calibration target (QTRgui: 
tools|options|calibration mode) what dMax do you get?  This is the 
best that you can hope for.  If the canned profile yields lower dMax 
then the likely culprit is the gray overlap that mixes in some of 
the next lighter ink into the black.  It is often a tradeoff between 
a smoother ramp aided by overlap of lighter shades and dMax.

I wish Roy would allow different overlaps between each ink pair 
rather than the one-size fits all.  I'd use no overlap with the 
black ink (maximizing dMax) and some overlap among the other lighter 
shades to help smoothness (say 10 to 20%).
