Thanks for describing your working procedures. Sounds like you have
developed a very efficient way of making carbons which should have
the same surface and dimensional characteristics of those made
in the traditional way.

Any ideas how this could be adapted to 3-color carbro?

I just checked this with the color tissue I am currently balancing.
There is not the slightest bit of dichromate left in the relief after
going through the entire process. Of course, with the traditional
process there are quite a number of steps when the tissue/relief
is in water. First, it is soaked for about a minute before being
squeegeed onto the plastic temporary support, then it is washed in
warm water for 6-8 minutes, then in cold water for another few
minutes to allow the gelatin to set.

Well, after all this time I still have a pretty good head of hair and
I rather like the idea of developing the reliefs separately rather
than on top of each other because that give me the flexibility to
re-make one of them if color balance is off, which has often been the
case for me. However, the problem of registering on a soluble transfer
paper *changing size all the time* as you state is really
a bear. Does anyone know of a dimensionally stable material (paper
or otherwise) that could be used to make a soluble temporary support?
It would have be to able to breathe, otherwise the relief would never
dry.

About the masters speaking, might need to count me out of that group.
I am now in the second week of trying
to balance a color tissue set with new pigments and I definitely
don't feel like a master. I am still confused by the problem and
have no answers, but at least I am confused and without answers
on a higher level than before.
