QTR-Quadtone RIP

When you use the Convert to Profile option, you will select either 
Gray Matte or Gray Photo at the destination profile.  In that same 
dialog box, you will see a BPC (Black Point Compensation) check box, 
and another drop down box where you can choose your rendering 
intent.  Choose Perceptual.  That ought to do it.
