Diana,

All processes that use FAC are somehow problematic in the department of
getting "in" the paper. You need relaxed (humid - not wet!) paper while
coating, to have the sensitizer effectively soak in the paper. You don't
need damp paper while exposing (if you aren't going for the shortest
possible exposure time, that is...), actually, damp/humid paper during
exposure is a problem with processes that have FAC sensitizer; since
negatives tend to stick to the paper and/or negatives peel the topmost
fibers from the paper giving extra grainy / fibrous tones...

Regards,
Loris.

Hmm . . . that's so odd.  I really have to humidify my papers (for
cyanotype)-- literally holding both sides of the paper in the steam, until
the paper actually feels somewhat damp, for cyanotype to work for me-- no
matter what paper I use.  Otherwise, the emulsion just comes right off in
the water.  That's why I'm so surprised that  
humidity would be the issue.   Maybe it's just weird water up there,  
full of weird toxic stuff. :0
