Lee,
There are two ways of going about this. First, adjust the Epson profile
until it visually matches a SWOP Certified Press Sheet. This, in my view, is
the best method and, if I'm not mistaking, the method used by SWOP themselve
to qualify SWOP Certified Proofs. The other method is a numeric method and
uses DeltaE as a pass/fail criterion. Using PrintOpen's iterative correction
proofing or GMG ColorProof RIP (or ORIS ColorTuner, I'm told?), the Epson
profile is edited iteratively until a low average DeltaE is arrived at, like
less than 1.0. The reference dataset is CGATS TR001:1993 which Klaus Karcher
aptly said that it should be public domain.
In principle, the numeric method should agree with our visual assessment.
That is, if a proof is on average less than 1 deltaE away from TR-001, then,
it should agree with our visual sensation as well. But I have yet to see
this on a SWOP proof, personally, because it's not possible to order SWOP
Certified Press Sheets from PrintTools.org since last year and I never got
any of the older SWOP Certified sheets :(
