Wondered about those "non-permeable" sheets. My blotter
book was set aside years ago in favor of a corrugated board
stack dryer. Although the prints do come out of the dryer with
nothing more than a hint of emulsion side curl they do over
time, unweighted, develop some more emulsion side curl.

As it is the stack is built by alternating layers of board,
hydrophobic sheets, and prints; a same sheeting each
side of the prints. Perhaps I should be using a less
permeable sheet emulsion side for long term
flatter prints. Dan
