You probably used the wrong profile.  

Also, QTR prints will often look light compared to what you're used to because it uses a strictly linear response curve.  If you have your Photoshop CS4 gray working space (Edit > Color Settings) set to Gray Gamma 2.2, I have a curve that I apply (can be a layer) just for printing that adjusts the print  densities so that they'll match the monitor view of a Gray Gamma 2.2 gray working space.  The curve is in the profiles zip and is explained in the UT14 PDF.

See page 4 of http://www.paulroark.com/BW-Info/Making_B-W_ICCs-GrayCard.pdf for the locations of ICCs in many popular OSs.

No, you can make your own full inkset profiles also. There are quite a few UT14 QTR users who will probably share their profiles.  You might want to join the QTR forum at http://tech.groups.yahoo.com/group/QuadtoneRIP/

The QTR profiles, in Windoew, are in a 1400-MIS folder under C:\Program Files\QuadToneRIP\Profiles.  Once you place the profiles there, you need to open them in QTR's Curve Creator and save them.  That generates the *.quad files that QTR then actually uses.

It's often best to start with papers for which there are profiles. 

Good luck with the B&W.
