(Ah, you are local... First read Gary Hunt's post, then this one.)
I find it helpful to keep the mounting temperature under the boiling
temperature of water - steam can give you problems. Using tissue designed for RC papers, even when mounting fiber paper, can help.
Do not use Photo-flo to aid print drying (I learned this the hard
way). Make sure the mounting surfaces are free of grease, wax, etc.
Use even pressure on the print after pressing until it is reasonably cool. Durned if I know, after that.
Hope This Helps
