Here's one of the more rare (and esoteric) ones:
A client prints a lot of duotones (real duotoned with Black and a Pantone
color) and (tries to) proof them on a Canon CLC1000.
He generates the Duotones (say a blue one) in Photoshop and prints it as
usual in PS 7 using the custom proofer profile, and get blue results, not
unlike the final offset print. When he places the same duotone (saved as an
EPS) in Quark he'll get purple prints. As Quark can't handle Color
management with EPS files this is to be expected, BUT...
Some time ago in another version of Photoshop (with unknown settings) he
generated duotones as well. Now when he placed these duotones in Quark 4
they WERE blue, and the printout was very similar to the one obtained in
Photoshop.
When opened in Photoshop both old and new duotones look and print about the
same. If both are placed in the same Quark DOC, one is blue and one is
purple.
Quark 5 has been set up to try and use profiles, and CMS off and what have
you. Photoshop files are printed using the standard Print Space window.
The client of course prefer the old style way of working (no CMS where the
color match) for Duotones, but like the accurate color when using a printer
profile.
So the questions are:
Exactly what factors are involved when creating a Duotone in Photoshop an a
Mac running OS 9.2.
ColorSync control Panel?
RGB or CMYK setup?
CMM?
What else?
Have something changed in the encoding changed between PS 6 and 7?
I've tried a myriad of options in both PS and Quark, but not matter what I
come up with, Quark prints all my supposedly blue files as purple, but all
the clients old duotones print like they should - blue.
As this happens even when you place these two files in the same Quark doc
(old is blue, new is purple), it must be something in the way the duotones
are created between PS 6 and PS7 that makes the difference.
When both old and new are printed in PS, both look blue, and very similar...
And I can't figure out what the difference is, and thus replicate the
former, blue, results on the proof'er...
