QTR-Quadtone RIP

I am brand new to black and white printing, as well as new to the 
Quadtone RIP software.  

I am not yet sophistacated enough to develope my own curves but did 
come upon the following:

Using Matt Chapin's curves for the Hahnemuhle Pearl paper, I was able 
to produce a very satisfying print using both of his curves in 
splittone mode and with the gloss optimizer using the OEM inkset.

For the highlights and midtones I used an 85% cool and a 15% warm tone 
and for the shadows 100% cool.  

I also reduced the gamma to -10, but that had more to do with my 
particular print and not the curves themselves.
