QTR-Quadtone RIP

I'm waiting for an order of the Greenpix Warm Tone paper from Red 
River.  I'm a relative novice working with QTR but otherwise 
knowledgeable with the workings of profiles etc.  

Does anyone have any experience with this paper and QTR in any printer, 
the Epson 1280 specifically, and the MIS-Eboni UT2 inkset?

Thanks, Mike
