Well, I understand. But in both UIs I see (Splash Server 4, EFI), it's for
applying TO profiles, not in substitution of. (Actually, neither of these
particular RIPs allow these curve adjustments as substitutes for ICC
profiles.)
Say, you're a little hot in the magentas for your profile, and you don't
want to or can't reprofile, so you'd like to apply a little curve in the
RIP. What would you do? Output ramps separated for and run through your
profile, measure with densitometer, then... I'm confused here. I guess
this is falling under your "desperate fixes" category...
In the real world, I just bought Doctor Pro (thanks for the advice everyone)
and I'm gonna edit the damn profile, but this curves features seems too
ubiquitous not to be able to use in a pinch, and I don't get it yet.
