I regularly dry my images when freshly coated in front of a fan, without
heat, however. Generally, it should come as no surprise that I find it
useful to stick as much to a set up routine as possible: fixed drying times
(10 minutes in front of the fan at an RH of about 50 %), observation of RH
and temperature. By the way, I remember at the beginning of my experiments
with multiple coating, I dried a paper with the help on silica gel. It
permanently shrunk out of registration.
For me, exact registration is one of the most critical matters, and though
I try to take great care, I still feel not guarded against nasty surprises.
