Yeah. I think that's a fair assessment of the expectations.
So I am not crazy after all ;-)
That's another thread, entirely...
Simplest test to run is output color managed proofs of the same
profiling target you used on press; utilizing each rendering intent.
Measure them all and see which one comes closest to the press
numbers.
Ah! But that would be trying to turn a RelCol rendering into an AbsCol
rendering!
I don't follow you here, Roger. I'm just suggesting a test. Different
engines are gonna' handle the color transforms differently, and
profiles are gonna' have varying characteristics. So, see which one
works "best". And you can open the whole chromatic adaptation can of
worms here.
If you'll allow a couple of other generalizations:
1) It's been my experience that clients don't respond well to the
paper simulation of an absolute colorimetric transform.
2) If you perform an absolute colorimetric transform, you MUST be
using a raster file - otherwise you'll have regions of paper
simulation and regions without.
3) If your proofing device is not a variable droplet device (or
something that can execute really, really fine screens), you can
probably forget about using an absolute colorimetric transform -
it'll just be too grainy.
Guess this is why GMG gives some options on the paper simulation.
