QTR-Quadtone RIP

Hi everyone I'm new to the list so bear with me, I did a search but 
can't find any info on my question.

I run a portrait studio printing on Fujihunt media with Epson UC with 
pk ink on an Epson 9600.

My monochromes are fine but obviously I'm on a quest to improve the 
final products. Presently I use Fujifilm Pearl Photo Paper 290gsm and 
Fujifilm Satin Photo Paper 270gsm both on roll stock. 

Is there anyone on the list using this combo that could get me off on 
the right track?

Wills
