For those of you who actually "know" and have done Tone Line along EK's process what do you predict would be the issues of getting the finest quality line outcome? Sure shooting 20X24 film would be a cure-all but I'd be using 4X5 B/W. While I'm acquainted with the process, what I don't have a line on is how would dye based images (Pyro negs) contact onto a CPO (or something like CPO) film?
I understand that film base thickness, and clear or diffuse spacer, and the angle of the contact frame's glass to the illumination affect the width so there are optimum to keep in mind. My goal is the most elegant line outcome for 4/5 shooting film. In the darkroom I can contact onto 5/7 for registration and projection.
