QTR-Quadtone RIP

If you want to experiment with a commercially available Piezography ink set that will stick to film, the current Selenium MPS Black and Selenium K7 shades 4 and 5 are replacements to the Epson K3 inks. But you still need to find a way to create some sort of 3 ink curve for QTR and a way to control the contrast you are seeking...

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.
