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

Subject: G7 unlaminated proofs?
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!
