QTR-Quadtone RIP

Hi Bruce,

I've been trying to understand how you are getting this result.   The 
only thing
that comes to mind is not using Perceptual Intent and Black Pt Comp.
In general the profiles should work for both soft-proofing and printing 
and map
black to black.

So how are you printing and how do you see this change in the black?
