Graeme,

Depends on the degree of the match, no? I see a lot of good matches despite
what looks like RelCol proofs. Some clients are very vocal about the quality
of matches they get. Others, rarely express any opinions.

That's what some clients are expressely told. But it does not keep them from
complaining anyway -- they just don't get it one way or another.

Quite true. I wish I could say something like "RelCol translates into more
compromises than AbsCol" but I have not tested this out rigorously.

Thank's for reminding me, Graeme. So, if I was to proof on the exact paper
my press profile was created on, say some Number 5 coated paper, and I
happened to have that exact same paper in my inkjet printer, at the time of
creating the proof, you would consider that the two white points (source and
destination) match perfectly / absolutely. Therefore, in this instance,
there wouldn't be any differences between AbsCol and RelCol rendering?

That's a common situation in proofing.
