Title: Re: G7 unlaminated proofs?
I cant see this working with inkjet proofs because the lamination effect on a printed sheet is significantly different than what is on an inkjet proof. If you have a dot proof like a FinalProof or PolaProof it would work fine but I let the profile make up for the majority of the lamination shift.

Jon,
I’m not sure I know exactly what you are asking, but I’ve been through a similar situation, albeit with Matte Lamination, not gloss. We do all our printing overseas in Asia so we work with press proofs. I’m in the commercial printing business, focusing primarily on very high quality books (covers and jackets), notecards, postcards, 4/C packaging (notecard boxes, puzzle and game boxes, etc…), and other items that require either gloss or matte lamination in the finishing. Gloss lam was not as severe a color shift as matte lam, so we focused primarily on perfecting our profiles with matte lam. Gloss is more predictable for us. Our workflow is as follows, assuming that as you indicated the profile has already been successfully made from the measured targets AFTER lamination. I’m assuming your standard NON laminated profiles are already on hand too.
We proceed with our normal proofing process using whatever non lam press profile is applicable. In our case we profiled our pre-press house press proofs, rather than the printers, since the later has so many more variables, and since none of our printers have a problem matching press proofs from this pre-press company. We produce the first set of press proofs, without lam, using the normal CMYK press profiles for the appropriate paper. After all corrections, reproofs, and final approvals are made by the client, we then covert the files to the LAMINATION profile, and reproof one more time. This proof now represents what the pressman should match, WITHOUT the lamination. It will look different than the signed client approval obviously. We also have a copy of this proof laminated. Do not show this laminated proof to the pressman, as this will only confuse him. This laminated proof is only used for our internal check to make sure it matches closely to the client approved proof. You may also show this to the client and get a final approval just to be safe, but the un-laminated proof is what goes to the printer. Did this help? Or am I missing your question?
Regards,
Bob

This is for all of you G7 people out there. I have set up our proofing system for G7 using the published data set and verified the color match with IDEALink Curve software. Its a spot on match. 95% of everything that we print has lamination on it so of course I put lamination on my proofs during the profiling process. My question is, how can I get a proof that resembles a press sheet before it is laminated? One would think that profiling an unlaminated press sheet would work but this has not been successful for me. I am using ORIS Color Tuner on an Epson 9800. The match is obtained using ICC profiles instead of using ORIS’ colormatching system. I am stumped. Help!
