Thanks for your response.
You are correct I am obsessed with collotype. I find that it has become a
way of life. I have a small letter press, a table top model made by
Gearpress. I have used glass plates and I have used small aluminum plates.
What I have been experimenting with recently is x ray film. I had thought
to fix out the film first but I did not find any reason to do this. I must
admit I have not been happy with the results. Why do you fix out the
silver? Is it that the bromine’s are washed out as well? Since I have been
attempting to make 8 x 10 sized prints have been looking for a stable
support.
I have been using glass but I think I shall try zinc or even steel plates.
Thanks again,
Mark A. Morrill
