Hi Steve,
I don't have much to add to the comments on this thread, but I'm
following it with a great deal of interest, as I am doing research for a
pre-press proofing system for our company, and I was just looking at the
GMG ColorProof/Epson 7600 combination, as well as similar systems, in
the IPA Color Proofing RoundUP from last spring.
One concern I have about using an inkjet proofer for pre-press is the
stability of the prints after the first 24-72 hrs. Our current Epson
paper/ink combination has an ink migration problem that makes it look a
little less red over a 24 hr. period. Could this be part of the
stability problem you're having?

We are a mid-size fast growing printing company that
dove into the realm of color management. We got rid of
our old proofing devices and went with Epson 10600 and
9600 proofing devices. We had color consultants, (Two
different consultant groups), come in and run
linearized press tests to come up with dot gain
curves, and a press to proof profile that was used to
run our Epson proofs using GMG software. We are
experiencing difficulty at times making that proof to
press match and our press room foreman gets upset at
the trouble this direction has taken us at times. Some
of these issues are mechanical such as banding in the
proof which gets to the press room by mistake. Others
are a press issue, and yet some defy reason. This
brings me to my point. I know that in GMG you can
Calibrate the Epson proofers back to a state of
calibration based on the MX3 file, but I have to
assure good proofs beyond that. I need some
software/hard ware that I could use on a daily basis
to check any given proof and be able to illustrate
that the current proof is within a Delta E tolerance
from proof to proof. I tried to configure a way using
the control strip in GMG on the proofs and reading the
data in using Eye one and Profile Maker measure and
Compare tools to give me a Delta E reading
comparision. The problem is there are 46 patches which
have to be read one by one by hand and the Eye one
lacks some of the true densitometric features that
make this an easy and or accurate task. Can anyone
suggest of any such automated accurate pakage that I
could use to accomplish this task. Our company is in
desperate need of quality control tools for this, so
any help would be greatly appreciated.
Thanks in advance
Steve Lehning
