QTR-Quadtone RIP

I am looking for some advice on the following:

I have a 9800 setup for dye sublimation using only cmyk color set. There are no light colors as all.

I want to be able to print more accurate black and white images with the dye sub ink.

Has anyone used Quadtonerip for this type of situation and/or what kind of pointers do you have?

Thanks for any help!
