Couldn't the ultimate criterion of good profile matching be whether the
proofs match the actual printed results?
For instance, when profiling any presses, I always include some (SCID or
other) images in the test form. After creating the profile, when outputting
on an inkjet printer, using AbsCol, one would expect the resultant press
profile to simulate with some degree of accuracy the printed images that
were part of characterization, no?
What if the proof does not simulate the printed results on press? What if
there is a visible global red cast in the proof? Or some light skintones
being too magenta and some others being yellow? Grass being too saturated?
Etc, etc... That, in spite of inking being uniform -- same densities
throughout the color bar, same dot gain -- on the printed press sheet.
Do you blame the press profile? Do you blame the inkjet profile? Do you
goback and redo the characterization? Do you redo the inkjet profile? With
other profilers? With other instruments? Do you...you see, there is no end
to this. What if all profilers give the same biased results? All being
either too red or too yellow, all suffering from more or less the same
deficiencies. Then what?
I think that's when profile (press or inkjet) editing comes in to improve
the simulation.
