Hi Paul,
Hi Paul,
I'm sorry but I don't quite understand what you mean about the single sided
glass exposure frame.  The flexible membrane of our exposure machine has a
thin glass frame on top of it as well as a thick glass frame where we lay
our films.  Is this the same?

Anyway, thanks a lot for the suggestion.  This is the first time I've heard
of this and it might just be what I'm looking for.
