Digital BW, The Print

Windows xp pro.

I have just purchased a used 2200 printer with Epson Ultrachrome 
inkset & matte black.

I downloaded QTR 2.1f.

I need a little help clarifying how to use the curves/paper 
selections and blending. In the Curves dropdown menu evrything is 
prefixed by UC which I gather is the Ultrachrome inkset that I have 
installed. 

But many of the common epson papers & others are not represented 
(smooth fine art, watercolor, arches infinity, hahnemuhle photorag  
and so on...) Either I havent installed correctly or one can get them 
elsewhere ?

Those that are installed dont seem to have a Neutral gey tone option. 
For example EenhMatte (epson enhanced matte i presume) has cool, cool 
se, sepia & warm. But no neutral. I do see a NoBlack neutral and a 
None option, but not sure when/how it applies. All the other papers 
are similarly designated - cool, sepia, warm? 

Perhaps someone can please provide an example of how to set the 
curves and blends to get a neutral print on epson enhanced matte or 
hahnemuhle photorag (which are 2 papers I have some stock of).

This is probably elementary for most of you but even after printing 
out the help section and reading it a couple of times I dont quite 
get it.

thanks
Frank
