All of a sudden I am getting a number of blisters on my carbon prints.
This is air trapped between the wet emulsion and the transfer sheet.
The tissue is very well squeegied to the transfer sheet.
If I prick these bubbles the emulsion drys flat but little rings are
obvious since the emulsion has been stretched. The transfer paper
is Fabriano Artistico 90% (100% cotton) brush coated with ca. 3%
gelatin solution w/ 3% glyoxil hardener.
Thanking all in advance for their words of wisdom,
Cheers,
Al
