Re: Basic Step tablet/UV light piesography question

The RNP method is conceptually similar to Mark Nelson's PDN system. Both methods have a method for first determining the blocking density needed for your process, and the required density range, and secondly have some method linearizing with an .acv curve. Both methods work fine with printers that have inksets with good UV blocking. I have made good digital negatives with both PDN and RNP but you are limited with both methods by the Epson driver. I now use QTR because of the much greater control of individual inks.

For some additional information on UV lights see the article Light Sources for Contact Printing
