Dear Lee,
AFAIK, ICC profiles are not passed along in a postscript stream.
Therefore, your RIP does not know what color space your data is in.
What you have to do is the following:
1. Turn off Quark CMS. Place ARGB 1998 Tiff or EPS in Quark.
2. Select "Composite RGB" in the print dialog box when writing
postscript.
3. Set RGB input profile to ARGB 1998 in your RIP.
The procedure for Indesign is somewhat different:
a) You can turn off color management and output Composite RGB (or CMYK).
b) You can turn on color management and set the print space profile to
match your RIP's RGB (or CMYK) input profile.
c) In Indesign CS you can also turn off color management and set output
to "Composite Leave Unchanged," which is useful if you have both RGB
and CMYK elements in your design.
Quark 6 has a similar option as well (turn off Quark CMS, set output to
"Leave As-is"). Is that confusing, or what? I don't think I would have
made any headway without reading Real World Color Management.
Basically, you have two options:
Either, normalize all elements to the input color space set in the RIP
before placing them in the layout, and turn off CMS in your layout app
to prevent further conversion.
Or, turn on CMS in your layout app to convert everything to the input
color space set in the RIP. This approach has some limitation, as Quark
will not convert EPS data (Indesign CS will, to a limited extent).
Hope this helps,
Sunando Sen
