QTR-Quadtone RIP

I've used a 3800 with K3 inks and QTR to make transparencies (only a few so far) on Pictorico film. No coating has been necessary but I'm not sure how to get a more continuous low-contrast transparency. If there is a piezography inkset which improves on the K3 inks to do this I would be interested in purchasing them for use in a 4800 with refillable cart's.  

Cheers!
