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 hope it will helps.
