mainly because creating art on a RGB monitor, to be used on
many media, is not the same _activity_ as bringing this art to
_one_ particular printing press.
also, it is better when the art itself is separated from the
adaptation of
it for one press run.

the question is what is the curve for? is it artistic? then RGB is your
space. getting the plates right? then chain them together and do a
curve.

there is going to be no substitute for experience with printing presses
and especially the particular press one is working towards.

if that is really needed by some users (see the two activities above
and also "no substitute for experience") then a second view of the
file (View->New view) can be run with the projection pulled down.
might be hard on the processor.
