Jon, The heat drying of paper should in
and of itself change the paper. What you are probably seeing is a lack of
humidity in the paper and due to the speed change of PT and PD you may be
seeing that effect. PD gets slower with lower humidity so if your prints are
primarily PD then you may expect a slower print. The PT will get faster. What
you see will depend on how much of each is there, whether or not you re
humidify your paper and what FO or AFO are you using.
AS for drying the finished/processed
print, a room fan with the drying screens works OK if you keep a clean “house”.

Does the heat drying of sensitised (Australian spelling) papers result, in your
opinion, in one grade more or less
contrast? I use a hair dryer, as Dan mentioned he grew sick of but have not
been made aware by any of my lessons in and reading of the Pt/Pd process about
an effect on contrast.
PS: My first post/response to the list!
