Ciao Marco
Thank you a lot for yor answer.
The way I see it, using those values [C 90, M 70, Y 70, K 100] inside
a file
that has a newspaper profile embedded in it should just be avoided,
ideally
Such a colour has, no doubt, to be avoided, as it would invalidate the
whole file that would then have to be colourimetrically reconsidered.
However, my main concern is the risk of inadvertently exceeding profile
limits by simply assigning a different profile, using trasparency
methods
like Multiply and Darken or taking colour corrections too far.
I understand that this is not about color management but I expect
newbies
to have some sort of safeguard expectation once their files are tagged
and, as regards Photoshop, I'm afraid that the Info palette's ability
to display credible Lab values for off limits colours is just going to
reinforce this confidence.
I guess I'm going to have to stress a bit that "The Invaluable Role of
the 'Total Ink' Option" passage. ;)
Thank you for your suggestions about how to deal with these situations.
