Well, those numbers depend on the separation process. To get an idea,
you could install the "separate" plug-in
(http://www.blackfiveservices.co.uk/separate.shtml), get a color profile
from the printer, separate to CMYK and analyze the results. Not quite
sure how you would do about the latter. Using the histogram might be an
option, but I am afraid that there's no direct way to get that number.
But I might just be missing something. Perhaps someone else has a good
idea how to calculate it?
