QTR-Quadtone RIP

Hi Richard,

The main issue is you have too much ink.  Notice the flat spot at the
top end -- 1.75 & 1.76
When you've added toner ink you saturated the paper & didn't get more density.
Otherwise it looks like you have a nice smooth curve.

The fix is simple -- reduce all the ink limits by at least 5% (I'd be
on the safe side and do 7%).
