QTR-Quadtone RIP

Darryl

You don't state what printer/paper/ink, but assuming it's a UC curve, most
curves sets have a sepia curve. You could try that or try blending it with
the warm or cool curves.

A slightly more complicated approach would be to create a new curve by
modifying a warm or sepia curve by adding a small amount of LM ink (or
simply increasing it in the case of most sepia curves). A simple way to do
that is to use the Copy Curve From setting for the LM curve to copy the
curve from the LK curve. Then set the limit for the LM low so there is only
a small amount of LM added in proportion to the LK.

Looking at an existing sepia curve will show you how the Copy Curve feature
is used.

If the amount of LM needed to create your desired effect is small, you might
have acceptable results without needing to re-linearize the curve. You could
also make a small adjustment the shadows or gamma in QTR to compensate for
the additional ink.
