So selecting "Ink Black" is telling Photoshop 6 to simulate the Source black
point on the Monitor as opposed to the Monitor's actual black point? All
right, then, how is this exactly carried over to the Print Dialog Box in a
cross-rendering task? Does this mean that, if one selects "Proof Setup" as
the Source Space (Proof Setup set to RelCol w/Ink Black) Photoshop will
convert from Document Space to Proof Setup "Space" using RelCol ** w/BPC ***
? If that's what it is and I would tend to think that's what's going on, it
deserves to be made clearer.
Also, I am not convinced that hardcopy proofing should strictly be done
AbsCol all the time. OK, I understand that pressmen are a tough crowd to
please and only AbsCol will satisfy them when it comes to the plethora of
inexpensive paper grade used in the industry (think "Spartan Web" or some
other low #3 coated) : granted that's far from Premium Glossy Inkjet media.
But how is one to proof when the production profile was derived from a super
high quality grade such as Warren Lustro Gloss or Champion Kromkote, with a
relatively high white L* value (around 95-96) while the Inkjet media used
for proofing also exhibits a correspondingly high white L* value -- in the
order of 96 or even 97, like the Imation DesignBase or the new Dupont
ChromaPro? In those circumstances, I ask you dear fellow list members, what
good is it to insist on proofing AbsCol?
