QTR-Quadtone RIP

The banding is about 1/2 inch, regularly spaced, and pretty subtle. 
They occur primarily on the first half of the print in (blue)sky 
areas. I changed to 2880, dropped the ink limit, raised the gamma, 
and I got a good print.  2880 prints are considerably darker than 
1440.  And the banding is only noticeable on larger (9x19in) prints, 
which is what I'm selling.  Smaller proofs don't show the banding.

Thanks.
