I suspect something is kind of broken (or I don't understand what is going
on) but I will tell you that when you use Preserve Gray Axis and you pick a
perceptual intent, you get a really warm colored effect (not so with
Relative Colorimetric). However, if you pick Paper Gray, both Perceptual and
Relative produce similar (neutral appearing) output with of course different
gamut mapping. This appears to be a bit different from version 3.X. What
I've found with all kinds of printers (not just those using off colored
paper) is that IF I want someone to be able to use a Perceptual or Relative
Colorimetric intent with PMP 4.0 profiles, I must set the option to Paper
Gray, not Gray Axis. I'm wondering if anyone else (besides Ian) is seeing
this as well.
