Trying to print positive via PiezoDN for photogravure, any suggestions?

I have been printing on 7880 with piezo dn ink-set for palladium with great consistency. now I need to output positive transparencies for copper photogravure process. i can tweak files as i go, but to start with, it would be great to have classic positive image, close to my screen. Any suggestions as to what settings to use in PrintTool on a mac?
Thank you!
