QTR-Quadtone RIP

That's it in a nutshell:

I'm using an Epson 1280 to print black and white images converted from the original color RAW capture.  I use CS4 ACR to converted and manipulate the image into a monochrome image.  I'm printing on Red River Greenpix matte paper.

Can someone please give me the recommended settings for the QTR-GUI.

Thanks, Mike
