Carbon - Double Transfer Paper

[ciocc]

Hello -

I'm new to carbon transfer printing. I've made eight single transfer carbon prints so far this week, but already I want to try double transfer. I wanted to continue to use fixed out photo paper, but Nadeau's book indicates that I can't do that. He states that I need to coat a paper with a relatively soft gelatin for double transfer. He states that a single transfer paper cannot be used as soon as dry, because quite a bit of time is need for the chrome alum to harden the gelatin. However, he does not indicate how long I need to wait after drying before I can use the double transfer paper. Does anyone know? He states that potassium alum be used, not chrome alum, because the gelatin needs to be softer. So I take it I wouldn't need to wait as long? Also, what is recommended double transfer paper if one prefers a very smooth surface, about the weight of Ilford MGIV fiber paper I've been using for single transfer? Thanks in advance for any and all assistance!

The double transfer paper can be used as soon as the gelatin sizing dries. The transfer from plastic to final support with double transfer is made with cool water.

There are many suitable surfaces. I would recommend a 90lb hot press water color paper. Fabriano artistico makes a nice support, but many others do as well.
