>From my experience, paper dimension always has to be considered relative to
the humidity of the air in which it is being measured. As I print large
(20"x24") gum prints using four or more coats, I have dealt with the
registration issue by adjusting the humidity of the paper. When I am in a
hurry, I sometimes hang a print over the wood stove in the studio. The
rapid drying and excessive heat causes the paper to shrink to a far larger
degree than if left elsewhere in the room. However, moving it into my
darkroom, with its higher humidity, returns it to a condition in which it
can be made ready for another coat.
BTW, drying a print over a wood stove belongs in the "Don't Try This at
Home, Dept." If too much heat is used, the paper can be "warped" to the
point where it is ruined. And, even though far more of my prints wind up
combusting INSIDE the stove, there is always that possibility.

Since there is so much discussion on paper shrinkage, and we all know
that speed of drying affects shrinkage, (right? Is it safe to assume
that?) how do you dry your alt prints?
I usually just hang it up, whether it's just coated with emulsion or
has been "developed." But I have been toying with the idea of a
drying cabinet, using moving air and perhaps low heat to speed up
drying. This is especially necessary in the humid South during Summer
months. Could someone with such experience share them with us? Is
there more uniformity in shrinkage when dried this way? What do you
use as a heat source? Etc.
Thanks.
