I tried it, but can't get good density on OHP.
Sb. reported good results if i remember correctly, beeing able to peel the
plastic right off.
BUT, if you look at the silicone paper discussion a while back it is much
what you want.
Basically you spread some RTV silicone, high temperature variety, with a
squeegee on a piece of ordinary paper, let cure.
This will allow you to make nice black transfers with no soaking etc. (can
just be pulled off).
I had no opportunity to finish my development of this method, i'm quite
sure it can be used for transferring resist, but so far i have some toner
density/pinhole problems with it. (the etchant goes "through" it in
places). When using paper this does not happen (not sure if it is the
coating or something else). Anyway, the silicone paper transferred stuff
looks fantastic and i use it for legend and panels and stuff. At some
point i'll look into it again for resist. The paper can be re-used, since
all the toner comes off but it can also be cleaned with acetone.
