Dan, I humidify my paper using a room humidifier built into a 3'x3'x3'
box. The humidifing box is keep at 58%rh. I work with a variety of
papers, including platine. If you are going to start to humidify your
paper, follow the advise of Terry and Luis, and change one thing at a
time. You will notice changes in speed and contrast, unless of course
the humidity is already at 55% +/- 5%. The total expense for humidifier
and materials was about $100 US dollars. It allows me to adjust the
humidity to New Mexico "natural" of 18%RH up to 90%RH.

Dan, might also allow the emulsion to soak in for about 1 minute 30 sec.
Adjust this based on RH of the coating environment. Waiting 5 minutes
seems way to long.
Good luck,
