While I'm feeling clueless, let me ask another question. Or two.
One of the printers I've been profiling is a Canon iP8500 using after
market inks and paper. The resulting colors are very good, but using
the perceptual intent yields images with slightly lower than desired
contrast. I've been using an abstract profile with "profile" to tweak
the contrast. The abstract profile was created by adjusting 1024
patches in Photoshop with the "Curves" adjustment. The patch values
extracted, (yet another utility) and converted to the abstract profile
Is there another, or easier way to do this?
The black ink I'm currently using (Lyson Fotonic) has a blue cast. The
paper white reads as slightly blue as well. The default perceptual
mapping places the gray axis between the white and black points,
resulting in a blue cast to resulting images. I adjusted the gray
mapping factor in "profile" to a value (0.4) which yielded a more
Again, is there another, easier way to do this?
Thanks in advance for any help, and please pardon my ignorance.
