My Corrugated Board Stack Dryer has evolved some.

Interestingly with corrugated board the waving only
occurs if the print's outer edges are placed close to the
open ends of the corrugations. Edges within the stack and
those parallel with the corrugations show no sings of waving.
Likely those using platen drying methods, heated or other
wise, will observe the same.
I placed prints deeper within the stack and that cured my
minor case of wavy outer edges. Also, I managed to reduce
the post dryer development of the inevitable gentile concavity
towards the emulsion side by drying emulsion to emulsion
with a separator twixt. So the stack now builds thusly:
C. board, separator, prints, separator, prints,
separator, C. board. Dan
