Digital BW, The Print

I have been QTR in the last few days, with the Epson 2200 and using UC inks I have come 
up with a combination that gives me an almost neutral print by using 50% Premier Fine Art 
(aka Epson Ultrasmooth) (got the profiles from Carl Schofield's site) and the 50% UC 
-Neutral profile.

 In this method I have to adjust my image with a curve is Photoshop to equal the contrast I 
want on the screen. (My screens are hardware calibrated and I do press work so I know 
everything is working properly there.

 I was wondering if there is a profile out there that allows neutral prints with this paper or 
without me having to do the curves ?

How does one go about making a custom profile for QTR?
Do you need a densitometer or anything like that?

Using Mac OS X 10.3.7 and UC inks.

Thanks,

Jorge
