QTR-Quadtone RIP

Roy,
Some of the generated gray curves appear to be pieced together from three
functions, leading to \ufffdsharp turns\ufffd in the ink curve.
Is it possible to smooth that out somehow in a future release?

I\ufffdm using text files for the toner curves on a modified UT7 inkset, and I
see a definite advantage to not having discontinuities in the curve.  If the
gray partitioned inks had smooth curves, I believe I would get a smoother
gray ramp, which would allow the generate-ICC to work even better.

Best regards,
John Moody
