Is a hair drier still "recommended"? I use to use a hair drier (after waiting ten minutes or so to let it really sink in). But after getting asthma from the platinum dust the drier kicked up, I went to air drying (paper tacked to a wall with a fan blowing over the paper) -- and got better prints for it. I coat all the sheets I will be using that printing session, and once the prints are dry enough, I put them in a box to hold them until I need them. If your RH is very low, you can put them in a plastic bag to hold the moisture level.

Dana -- how does one determine "90% dry"?
