April 16, 2006, from Lloyd Erlick,
I hang my FB prints to dry regularly.
Prints up to and including 11x14 need to be hung by one corner only.
Prints 16x20 and 20x24 need to be hung by two top corners. The bottom
corners need no clips or weights of any sort.
Slow drying is essential. The more rapidly the sheets dry, the more likely
they are to curl. More dry causes more curl. Humidity in the drying area is
crucial, and must be monitored. Maintaining humidity in the human comfort
range is important in the darkroom, and it is also easy and cheap to do.
The comfort range is merely a fairly wide range of humidity that most
people will experience as comfortable, or at least not uncomfortable. Let's
call it 40% - 60% relative humidity. It is quite easy to keep a darkroom
within those boundaries. High cost enters the picture if the range is
narrowed. For example, a range of 49-51% would cost a lot to maintain.
When prints are hanging to dry, it is best to have no air movement near the
prints, so no heaters or humidifier or dehumidifier placed close to the
hanging area. They can be placed at some distance if they are needed. If
the moisture from the prints themselves raises humidity, just leave it be.
It will not last long.
regards,
--le
