Basically you can characterize your perceptual RGB to print transformation chain with a normal RGB ICC profile; i.e. print a RGB characterization chart (with not too few patches), measure the printed samples, and run the profiler to create the profile [in the same way as you would create a RGB printer profile for a RGB driven printer under Windows]. IMO there is nothing special. (But eventually this is double profiling, and whenever you rebuild your printer profile, you would need to build a new RGB profile as well.) -Gerhard ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
