These sliders don't make any sense to me, so while I get 14,14,14,0 I
have no idea what 32+16+16 is supposed to be. It's not a very intuitive
interface.
IN any event, the fact the profile specifies 5,5,5,0 (% CMYK) for an L*
of 100 is peculiar. But even more bizarre is that when using this profile
in Photoshop with all CMMs I have, none of them map L* of 100 to anything
close to 5%. The highest value is 2% (which is bad enough - 5% would be
unusable).
