I am not getting black in the areas of the images that are pastels or silver
finishes (C:39 M:66 Y:95 K:11 and C:72 M:58 Y:67 K:29) when I build a 'No
Black' profile, but I do when I build a 'Skeleton Black' profile.

This is the question:
Do you set up the BEST rip with the densities and total ink limits 'before'
profiling, which leaves the profile to do less work, (kinda like setting the
RGB guns in a monitor before profiling)
Or
Let the profile define do all the work, as with the Mach1 Rip ?
