QTR-Quadtone RIP

I'm not a Piezo user, so I don't know for sure if re-linearization is even
allowed with those profiles.  However, if it is, then a reasonable scanner
might be all you'd need.

I suspect QTR's own profile builder would do a fine job with the Piezo
inkset anyway.  One of the main differences in Cone's profiles relative to
what QTR builds semi-automatically is the amount of overlap among the inks.
This helps reduce banding by having more inks firing at any given point.
This can be important on some printers, such as the 1800.  However, my 1400
is so relatively free of banding that I suspect QTR's system would be fine.


Additionally, QTR has a provision for increasing the amount of overlap.  For
example, this week with my old 7500 I had banding in with the default QTR
profile, but when I increased the overlap to 20, the banding disappeared.
