I can see that this could be a problem, a suggestion I would like to make
is to use a pricking tool, such as used in dry mounting plastic overlays
and laminates so that the mylar is impregnated with numerous tiny holes,
which should help to alleviate this problem
>Does anyone use plastic supports for monochrome work or would you call me
a fool ? :-))
You are no fool Stefen, my good friend Mike Shorter recently wrote an
article in
A.P.R.2 entitled, Carbon Tissue Making, in which he described a method very
similar to your own.
Hope this helps pete
