If you have thought about making digital negatives for contact printing with silver gelatin papers you might be interested in the following information from Jon Cone.

Although I don't plan to contact silver gelatin I am pretty excited by Jon's work with the K7selenium set for digital negatives as it also offers a lot of possibilities for alternative printing with an all gray ink set, which in theory should give better results than a color ink set.
