Suppose you have a CMYK image with four PMS spot color channels. Suppose the
CMYK channels were blank and suppose you issue the Merge Spot Channels in
the Channels palette after shift-selecting the four spot channels. Is there
any way to predict what the final converted CMYK colors will be?
I tried figuring the algorithm yesterday and I could not do it. Photoshop
must be doing some kind of blends in Lab, internally, between each spot
channels Lab values but there is nothing anywhere that I noticed that says
how these colors relate to the CMYK Working space? And the gamut mapping
that must be going on between the two.
The reason I ask is because, invariably, the results are much desaturated
compared to the pure PMS spot colors definition. I think I understand why I
am getting the colors I am getting but I'd like to understand the process a
little better.
