QTR-Quadtone RIP

Cody,
There are three Gray color spaces included with the QTR software; Gray Lab, Gray Matt 
paper and Gray Photo Paper.

Roy has included a paper in the QTR documentation in the CurveDesign folder that 
describes how they can be used.

I have configured CS 3 to use the Gray Lab space as the Gray working space. This permits 
me to leave my B&W images in the "native" working RGB space.

Thus when I get to the Print dialog and select Photoshop Manages Color, the working 
space shown is Gray Photo Paper or Gray Matt Paper depending on the paper it will be 
printed on.

Then when going to the QTR printer dialog I can select the paper preset and print.

Using this approach I can print onto different papers using QTR without having to do 
additional work to get a soft proof that matches the print.
