Re: "Saturation" versus "Perceptual" rendering intent -- problems with yellow

2007-11-14 by nealdryan

I have QImage and it is a lovely program but printing from Lightroom
provides awesomely fast workflow (which QImage can't match once I'm
using Lightroom for everything else) and excepting this problem
provides really nice results.  

Also, using my other available profiles, saturation intent and
perceptual intent are extremely similar while with the PrintFixPro
generated profiles they are dramatically different.  To me that
suggests there is the possibility that some change in the ICC
generated would solve this problem in a good way.
