Al,

I am still a bit uncertain about your working proceures but I will try to
respond to your questions. Let me know if I am off track in the resposne.

If you are doing a single transfer procedure onto a final support with
hardened gelatin you should position the relief on its plastic base in
contact with the paper support before the gelatin cement begins to set.
What I do is simply pour about 25ml of the 2-3% gelatin solution, at about
80 degrees F, on the final support paper, then immediately squeegee the
relief on plastic onto the support. Leave under pressure for 5-10 minute,
then set aside to dry. Repeat for the magenta and cyan image.

The soluble transfer paper *should* be a smooth paper with a very thick
layer of soluble gelatin. I prepare soluble transfer papers in the same way
as carbon tissue, leaving out the pigment. That is, I use about 75-100 ml
of a 8% gelatin solution to coat a 11X14 paper.

Please let me know if you have further questions.
