Al,

The problem is that you have a very rigid surface (plexiglass) in contact
with a thinly sized watercolor paper with an uneven surface. There simply
is no way for all of the paper surface to contact the gelatin relief on the
plexiglass. That is why parts of the image remain stuck to the plexi. To
make this work you have two choices, depending on how you plan to work in
tri-color.

1) transfer the gelatin reliefs from the plexiglass (or other polyviny
surface) using the so-called single tranfer method in the order yellow,
magenta, cyan onto the watercolor pape, using a 2-3% gelatin solution
as a cementing agent between the plastic and watercolor. The cementing
solution needs to be applied at each transfer.

2) transfer the gelatin reliefs in the order cyan, magenta, and yellow
onto a sheet of soluble transfer paper (a sheet of paper that has a
farily thick layer of soluble gelatin coating), then transfer this
image onto a final support.
