QTR-Quadtone RIP

Hello.  Does anyone have any recommendations to get the best quality 
black-and-white prints using QTR on the Epson 2200 using the UC inks.  
I am interested in profiles and other settings for Epson Premium Luster 
and Enhanced Matte papers.  Also, I am interested in any workflow 
advice in CS to create images that will produce the best prints.  I 
just started using QTR so any advice will be greatly appreciated.

Currently, I am using the UCpk-Permajet Oyster profiles (75% cool- 25% 
warm) for the Premum Luster with decent results.  However, bronzing is 
an issue.  I am pretty happy with the Enhanced Matte profiles (also 75-
25) using the matte black, but the blacks still do not seem deep enough.

Thanks again,
Bryan
