Several years ago, when I was printing cirkut camera
(panoramic) negatives (20-40" long), I had good success
slightly dampening the *back* of my gum prints when I needed
them to expand a bit to fit my registration pins. As I
recall, I used a damp cloth and a hair dryer to zero in on the
required size.. rather tedious. I haven't noticed any problem
with my negs. However, this may be due to the thickness of
the paper (Rives BFK). The small amount of moisture required
for the print to exapand didn't penetrate from the back to the
front (sensitized) part of the print. I can see why this may
not work with the thin papers that Judy is working with.
