I was readingyour Printcal tools and beginning to get that picture. At this
point I don't know what +/- 20% on the Epson RGB driver equates to...maybe it
is a big or small change. In any case, visual inspection, a few measurements
and reprofiling seems about all I can do without going to a RIP (which exceeds
my interest level). In any case, will Printcal give me the basic curves I'm
looking for? The advantage is automatic target generation, measurement and
graphing! As a test, I tried: targen -d2 -e0 - s50 -f0 testfilefakeread
Epson_premium_luster_profile.icm testfileprintcal -p -i -d testfile It
produced graphs for the rgb "primaries" that seem useable. But I could not
get Printcal to produce a black/grey curve (ie. based on targen -g50). Is
that possible?
