That's a lot of code just to do something that ColorSync can do with 1 line. I'd rather not go down such a costly path. > Ok, this is the point of cmsCreateProofingTransform(), you specify > the input profile, the profile for the device you are going to > simulate, printer in this case, and the profile for the device to > render the simulation, a monitor in this case.

Printing to a proofer is one thing. Soft proofing to the monitor is another. The user can turn on the proofer profile so they can see *onscreen* how it will print to the proofer and still have the printer profile in the chain. Input->printer->proofer->monitor = 4 profiles. > And this is how cmsCreateProofingTransform works. Thanks for the detailed explanation of why the printer profile would need to be added twice. So since I *do* need 4 profiles, I can't use cmsCreateProofingTransform. Will I be able to interject an intent at each step if I were to go down the path of creating multiple xforms with cmsCreateTransform or cmsCreateProofingTransform and then convert those to linked profiles, then use those to create a final xform? _________________________________________________________ Steve Mills Me: 952-401-6255 Senior Software Architect MultiAd [EMAIL PROTECTED] www.multi-ad.com ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
