Instructions
Store pages flat and place a heavy object on top of them, if possible. Do not lean the pages against a wall or let them hang off an edge.
Fasten the edges of the pages with paper clips if they are not too fragile. Tape individual pages to a stiff surface such as cardboard or fiberboard.
Keep pages away from moisture and high humidity, since water encourages curling. Use the minimum amount of water necessary when developing images on the pages.
Work out the curls with your hands if the pages do curl. Lay the curling edges beneath a heavy book if folding with your hands doesn't work.
