I can guarentee that the steel trays won't work for pt/pd. My first
experience was about 15 years ago with Eikoh Hosoe. He stayed with me in
California and learned pt/pd printing. He went back to Japan and went
through hell. It was in pre-FAX days (they had them, we didn't) so we
burned up a lot of money making trans Pacific phone calls. He said he was
getting absolutely no image at all. I shipped more chemistry two or three
times. When talking about contamination, etc, he mentioned his 20 x 24
stanless steel trays. I got suspicious. He changed to plastic and all
worked well. We've had a half dozen helpline calls from other printers
since then with the same problem.
My guess is that Kallitype and vandyke won't work either. Gum is no
problem. Argyrotype probably, cyanotype is a maybe.
