Re: How to apply curves in PS for digital negatives...

This is the very point of calibrating your system - actually, this is
the definition of (in this case) primter profiles. With a profile your
printer will "know" what to do with every recipe of RGB it receives to
deliver what you expect. If you don´t want to bother to profile your
printer (not so wise, because this would be more economic in a
not-so-long term), at least your monitor could be, to decrease the
number of variables on the process. I´m in Brazil, so I couldn´t 1)
make them for you, or 2) tell you where to have them done for you, but
it´s probably not so difficult to Google it in your area.
