In attempting to transfer some monochrome carbon images (test negatives and
accompanying steptablets) from temporary plexiglass supports to final
support paper, I've encountered a problem:
After the image is transferred and the paper is dry, the most dense
highlight areas, as well as the unexposed (safe edge) areas, have flaked
off.
I've not had this occur in previous printing sessions.
The papers used for this printing session are more heavily sized than in
earlier sessions. These papers received a 7% size, hardened in glyoxal.
Previous, successful, transfers from images developed on plexi were done on
papers with a 3% size.
Have I sized the paper too heavily? I'm working with Fabriano Uno, Fabriano
Artistico, and Rives BFK.
Thanks for your comments.
