That's for sure. Why perceptual though for proofing?
two potential reasons:
1. if the printer/ink/media combination does not have enough gamut to do colorimetric proofs of your
press
2. on high-gamut media (photo glossies e.g.) a colorimetric proof of a press with a much smaller
gamut just looks wrong (bad), even though a colorimeter might tell you that it's right. It would lead
us too far to discuss why in any detail, suffice it to says that it's a perceptual BP/WP adaptation
phenomenon. Of course one might question whether it makes sense to proof on a media with much more
gamut and/or much different WP/BP; I'll leave that in the middle for now, but it's not uncommon
(going all the way back to analog proofs like Imation MatchPrint and the like).
