Digital BW, The Print

Hello everyone. I've recently begun using QTR (through QTRGui) 
printing on an Epson 4000, alternating between Enhanced Matte and 
Premium Luster. I'm trying to follow the discussions about how to do 
some kind of soft-proofing/preview of what a print will look like in 
various cool/warm/sepia blends, but haven't (yet, anyway) been able 
to gain a sufficiently clear understanding of procedure. I don't 
have access to a spectrophotometer a la the Eye One (I use a self-
calibrating Sony Artisan as my display). I soft-proof color work via 
PS CS and familiar with that process, but can't get things to work 
similarly with QTR (though the actual prints from the 4000 are 
superb). Does this have something to do with the LabGrey space, etc. 
for download on Roy's site?

Anyway, a simple walk-through would be appreciated. Thanks very much 
in advance for your patient tutorials!
