Hmm, if the Illustrator file is only CMYK, then the colors you get should
be the same in Photoshop 6. If they were built with a named color system,
you could have a problem.
You'd think so, but if I have PS6 set to SWOPv2, Photoshop
re-interprets 100%K from Illustrator (8) as a gray.
FWIW, SWOP ink black (not rich black) is pretty light.
I have heard that before, but can't find anyone who agrees with it.
If I show a 4/c magazine ad point to the type, and ask what color it
is, everyone says "black." Of course, it's all relative, and it was
sort of a trick question, but it's definitely a problem when the
color in question was also defined as Black in the page-layout
program -- and which prints differently after Photoshop has its was
with it. There's no reason for PS to re-interpret 100%k as a gray,
regardless of how "light" SWOP black is: 100% SWOP K should be 100%
SWOP K in every program. Interestingly, "Adobe Photoshop 6.0 Studio
Techniques," page 215, shows 100%K as being just as dark as rich
black. Anyway...

Drat I don't have a copy of Illustrator 8 here, but in 9 and 10 you can't
have colors in different modes in the same document. I'm not sure how
Photoshop handles this. I would expect if you rasterize the EPS with mode
CMYK, any CMYK objects should have their color values preserved (black
should come out as 100%K if that's how it's defined in the Illustrator
file). The RGB color would get converted because in Photoshop of all
versions, a document is in one mode at a time.
Ahh, but Photoshop is in RGB mode, not CMYK. So I'd expect the RGB
color to stay as-is. So far I've had absolutely no luck in
rasterizing Illustrator 8 RGB in Photoshop 6. I have tried the demo
version of Illustrator 10, and with the out-of-the-box settings it
has the same problem. If I switch both it and Photoshop the Web
Defaults settings the colors don't change. I guess we now have a
reason to upgrade. :-|
See what happens if you copy the objects in Illustrator and past them
directly into Photoshop. Works when going into InDesign - not sure about
Photoshop but perhaps worth a try.
Funny, that works even though Open doesn't. To keep the black from
changing, I do have to either switch the it to rgb or use something
besides SWOPv2 as my cmyk setting.
Thanks,
