I have some fine art images to print which are basically nothing but quarter tones - shadows upon shadows upon black!
Is there a way to build a profile that might help with clearly defining these dark tones? I use x-rite profiler and iSis XL, and have used optimization routines before, but any tips for gaining shadow clarity, even if its at the cost of other tones, would be most welcome.
If your profiling software does not offer an option to specifically adjust rendering of dark tones, you can always output your patches to a TIFF and adjust its shadow rendering in the opposite direction of what you want to achieve, and print that. The profiling software will try to compensate for the more compressed shadows and build a profile that opens them up.
