Katharine:
I print my gum negatives through a halftone screen (paper, screen,
negative, light in that order), and get much better separation of tone than
when printed without the screen.
I believe the reason is this: gum sticks to gum better than it sticks to
sized paper. As a result, adjacent particles of gum tend to flake off
together. The presence of discrete dots of gum therefore allows the stuff
to adhere better to the paper.
My 2 cents worth. Best- Ed Stander
