Arrggghhhh!! I've been trying for two weeks to get a good coating on the Autochrome plates, and it continues to confound me. The first thing that I learned is that with my current setup, I can't use and water-containing chemicals in the coating, as they make the water-soluable dyes that I used bleed. This eliminated a gelatine coating. I also tried suspending the starch in some type of other liquid, and speading it across the plate using the liquid's surface tension. However, I cannot use organix solvents such as alcohols or acetone, as they destroy the dyes as well. I am thinking of using some type of an adhesive with the starch suspended, but this has proven to be quite difficult; I have epoxy, rubber cement, various glues and some silicone products. All of these either act as dye solvents, dry too quickly or are way too thick to coat evenly. Does anybody have any suggestions as to how to coat the plates? Perhaps I'm taking the wrong approach? Help Please!! To start of with testing, I have made a 1200 dpi mask on a color laser printer, which I'm going to do initial testing with.
