I misunderstood Sandy's original question -- having read it casually, I
thought he was talking about drying a freshly *coated print,* not drying a
fully *processed print.* My small familiarity with platinum printing made
clear that heat drying after a certain (measured) time of air drying was
essential to good contrast in that medium.

But in other processes that I've tested (cyanotype, VDB, kallitype, gum),
heat drying the *freshly coated print* cost both D-max & contrast,
depending on how hot & how fresh.

Many printers seem not to know this, so the point bears making.
