After years of trying various methods I'm currently having great success with the technique described above where the wet, squeegeed print is lain face up on a large piece of glass (I use a picture frame bought for peanuts from a charity shop- the frame helps keep the glass rigid and makes it easy to handle) and tape it all around with moistened brown gumstrip bought from the art shop, which I also use for the stretching of water colour painting paper. The next day the print is flat, sometimes with a wave, depending on the type of paper, and has a lovely lustrous finish. The brown gumstrip border that remains on the print after knifing it away from the glass I usually leave on, as it makes handling the print easier and makes it less prone to fingermarks etc.

Its become my favourite drying technique for FB.
