Richard, thanks for your response.
I must confess I've never used any profiling package besides the
custom CMYK profile feature of Photoshop. Well, I have calibrated my
monitor with X-Rite i1Profiler, but it won't work with CMYK profiles
unless you have purchased X-Rite's print profiling equipment.
What standard profiling packages are there out there for offset printing?
Best,
Alexander
