Yes, because :
a. in a studio presentation print only the Perceptual or Colorimetric
table in the inkjet profile is used (as the inkjet isn't simulating
anything), but
b. in a studio proof the Colorimetric table in the production profile
and the inkjet profile join, and if the colorimetric rendering is off
the workflow goes south.
It's probably pointless to try to ascertain preview accuracy through
measurement of a print and a monitor,
Yes, because :
c. for prints absolute, illuminant relative colorimetry applies and
Lab color tolerancing is just a matter of choosing your
spectrophotometer, whether you will sample once or multiple times
across the patch and so forth, but
d. for self-luminous devices absolute, illuminant relative
colorimetry does not directly apply, though you can use LOGO ColorLab
for scaling to D50.
