Mark,

If you have an Epson 2400 or 2880, I have a turn-key system for digital negatives using a subset of the Piezography inkset for Pictorico. It includes 5 curves that cover the entire range of darkroom papers by density. Piezography Digital Film is density based rather than UV based like color ink systems. We don't have any of the "venetian blinds" issues or banding as a result. Clean highlights in the silver prints without dots, etc...

You do not need to use PDN with Piezography Digital Film unless you wish to. It is compatible with it, but only the curves calculator portion of PDN (which is the PDN module that automates making curves in Photoshop). Because Piezography Digital Film is already linear, the curves calculator will only make creative contrasts which you could do on your own in PS. As is my system makes proper prints.

here is a link to a brief white paper on it:

Use Methodology 3 for silver prints. Meth 1 is for Alt-Process requiring density in the film greater than 2.0.  SIlver needs only 1.50 - 1.80. I use the 1.60 curve for Ilford Multigrade RC and fiber base. 

Piezography Selenium ink is a pigment that adheres and dries strongly on Pictorico. I realize your question may be directed at using color dye or color pigment. This is another possibility that you may not have thought of. When I made the Digital Film system, I wanted to imitate continuous-tone silver film. So the negs my system makes, look like and perform like silver film. You contact print them. They are strong enough to be stored and re-used.

regards,

Jon Cone
