It kinds of defeat the underlying philosophy of color management modularity
and device independence, you know, one calibration, one profile that
describes a monitor independently of any other devices it can be connected
to (but I can empathize with your pains). Have you ever confirmed for
yourself that the color you were seeing on your monitors accurately matched
your proofs, on strict DeltaEs grounds? I recently experimented (I always
experiment) a great deal with the screen to proof match between an Eizo
CG221 and a SWOPv2 proof, ran on GMG Semimatte250 paper. The average DeltaE
between USWebCoatedSWOPv2 and the proof was less than 1, with a max of 3.
So, evidently, on strict colorimetric grounds, a rather high degree of
matching was to be expected between Photoshop and the proof, wouldn't you
say? Well, I was in for a surprise. Read on.
Using BabelColor CT&E and the EyeOnePro as the judge (the SWOPv2 proof was
arrived at with the same EyeOnePro unit albeit mounted on an iO), it turned
out that the color I was seeing on screen matched to less and one Delta E ab
the color measured on the proof, not bad at all : but the monitor kept
appearing ever so warmer to my eyes than the proof. Which, as you can
imagine, bugged me to no end. I managed to get rid of the mismatch by
cheating on the monitor profile -- could have done using Mike A2B1
technique, as well -- but I did it differently. The point is, in the end, I
had to educate myself that I had to accept a slight mismatch between the two
devices, because of visual adaptation (the proof paper did exactly show D50
chromaticities) or some other factors I could not come to grips with. The
alternative, as you found out painstakingly, is to lock the monitor in a
kind of close-loop arrangement. But the minute a different observer comes in
the door or there is a change of media, you need to create yet another
"manual device link profile".
