     The traditional way is to dry fiber prints emulsion side down.
There is a rational to this. The idea is that curling of prints is
mostly due to the emulsion shrinking more than the sup****t. This
shrinking is minimized by slowing down the drying. That happens when
the emulsion is against the screen which limits the contact with the
air. Old style screens used cheesecloth which held some water making
the emulsion side dry even more slowly.
     Since the sup****t side of RC paper is dimensionally stable this
drying scheme is not needed although screens may still be convenient
for drying. RC is usually dried emulsion side up.
     The differential drying gotten with a screen is also the reason
blotter books and rolls have a non-permeable sheet, waxed paper in the
very old ones, interleaved with the blotters. The idea is to put the
emulsion against the sheet so that the drying takes place mostly from
the sup****t side minimizing curling.
