This is really one hard process. I have been working on this a week solid and have only two successful prints. There just isnt enough info out there on how to do this so Im guessing at almost everything. Like should I flatten the interpositive? Yes, found that out. What is removing too much paint? What is not removing enough? How long do you leave the print in the etching bath and does it matter how much paint is on the print? YES!!! So much that I couldnt find anywhere and Im still working on it.
I really love the look and I love working with oil paint so Im going to keep at it. Gumoils and Gum Bichromates are just different enough to give me two different processes to work with.
