I wouldn't say it doesn't work, I'd say it doesn't do what we're
after. It seems to do what the name implies, which is make a rich
black by it's traditional definition, adding CMY to K, increasingly
down the scale resulting in, well, a rich black. Unfortunately it also
doesn't seem to take into consideration all of the info in the
original profile to add CMY in a neutral way, at least a quick test
failed to do so today.
I wish I could tell you more, but every time I try it I get something
whacky and just give up.
I've got an out of date demo version here, perhaps new versions would
be better, there were also no options or control, just does what it
does with little explanation.
Since I think this started off with how to make a profile that
replaces all neutrals with K, and some neutralizing CMY, I have a
feeling this feature is for something entirely different, increasing
TAC etc..
Maybe?
