I don't remember the ColorSetup allowing a rendering intent at all. I
think the only chance to set it is when installing the profile. I
tried both Relative Colorimetric and Absolute Colorimetric. I've also
tried changing the default rendering intent of the profile using
ColorThink, again with no change.

Hello, Glenn
I've seen such effect with ExpressRIP (Harlequin OEM).
I've the reason of such effect.
In ColorSetup you have many choises for Rendering Intent :
1. Autoswitching
2. Perseptual
3. Relative Colorimetric
4. Saturation
5. Absolute Colorimetric
6.(ICC Autoswitching)
7. (->ICC Perseptual)
8. (->ICC Saturation)
9. (->ICC Relative Colorimetric)
Am I right? If 'yes', then I have a question to you. Do you use Intents
choises 1-5? If 'Yes' then you are wrong. These Intents are RIP defined,
i.e. RIP RECALCULATES your profile's intent. So n this case you should drive
from RIP separation settings. To perfirm convertion in accordance with you
profile's default separation try 7 or 9. I've found that during using
PrintOpen3 profiles Intent 7 corresponds profile's Print Table and Intent 9
corresponds Proof Table.
I loaded two profiles I created with my lovely Spectrocam into a
Harlequin RIP running a Kodak DCP9500 last week. The input profile is
of a Dupont Waterproof system and the output is of the Kodak. It took
me awhile to sort all this out on this blasted PC, but so far so
good. The Harlequin allows me to select the rendering intent of the
profiles when I "install" them. The problem is that no matter what
rendering intent I choose for the Kodak profile, the output looks
exactly the same. It's much too white--light grays dropping out
entirely and colors looking much light. I went back and edited the
profile to darken it, loaded it back in, and no difference! So I did
the same thing again but this time darkened it drastically to see
what would happen and again--no difference! It's as though the
Harlequin is using the input profile, but ignoring the output profile
or at least ignoring certain attributes of it.
