I just bought Kodak Custom Color ICC 2.0 and found out that if I tune the
visual appearance (CMYK > LAB or RGB > Lab) of a profile and use it in
PS 6
the change is not displayed.
Trying to think back to the ProfileMaker 3.0 ProfileEditor module and
the rules there. It's a raw editing tool that let's you work with
what's really there which is one of the most confusing things I know
-:). You don't see a difference if the image which is open as
reference for the edits is CIELab and do if it's CMYK. There's more
to it than that, though.
As a rule if you want to edit something then only edit the forward
Lab to device CMYK perceptual gamut mapping in the CMYK production
profile, never the colorimetric back transform from device CMYK via
CIELab to monitor device RGB and proofer device CMYK.
