I used blotters for a while with good results. A few layers between the prints allow for even drying and flat prints _BUT_ I found that I had to move the damp prints to fresh, dry blotters at least once during the drying process. The one time I didn't it was a lint nightmare. I just re-soaked the prints in water with a bit of Photo-Flo and saved the prints but never used blotters again. Too much hassle. Now I just hang them until dry and give them several seconds in the dry mounting press. Fast, Easy and the results are always perfect.
