I am not sure if my method is best but I set up an electric fry pan (that has never been used to fry) with water at about 180 degrees and when I take the lid off it lets out a bellow of steam. I steam a paper before I coat it then let it sit for a short while. Then after coating it I wait a bit longer than usual for the sensitizer to soak in and then dry it with a hair dryer. Then I re steam the coated paper and put it on a dark shelf and let it sit at least another 10 minutes for all the paper fibers to be able to become equal in moisture content. If you can work out your routine to let it sit a half hour at this point it is even better.
anyway that is what I do.
