QTR-Quadtone RIP

I'm curious where you are reading about "curves with calibration=yes".  A very
long time ago you need to make curves for calibration but that was changed
to just use the calib ink limit slider.  It sets the ink limits for
all the inks together.
I thought I had all those old references removed.

In any case once you decide on ink limits, you start making actual curves and
will no longer use the calib mode in printing.
