I ask: huh? I'm too...er... dense to understand this, forgive me. I know
what dot gain is, have an idea what dot area is, but don't understand how

Applying a curve in a RIP is editing the profile! It actually generates a
new profile. It's just not as powerful (i.e. doesn't have all the tools) as
a full-blown profile editor, which I am now going to use.
