QTR-Quadtone RIP

I am just starting to learn to use QTR.  I am on a Windows XP machine
so am using the QTR gui 2.5.2.1 interface.  I am outputting to a 2200
with UC inks.  When printing negatives to Pictorico OHP I have been
using the matt black ink.  One of the settings on the interface is
media type.  I have been using "Transparencies" but am wondering if I
should be using something else.  When printing to the same material
from Photoshop I used "Enhanced Matt".  Is there a recommended setting?
