[argyllcms] Re: Argyll vs. manufacturer's profile

OP means original poster.

I use the Pixl test image to evaluate my profiles.

I have used Monaco Profiler, Profile Maker Pro, and Argyll with
various spectros, and indeed there is always a perceptible variation
in the sky hues, from blue to purple. I was never able to figure out
why. There is a well-known "dense blue turns into violet" problem in
printing, due to a hook in the hue when density goes up, and this may
be the cause of this blue issue. A good test would be to run some
profiles with a huge number patches through each profiler and see
whether the resulting closer measurements result in more similar
results.

Anyway, if you want a Monaco Profiler profile, just download
colorport, print the target and measure it for the big 1728 scrambled
patch target, and send me the measure results.
