I have had problems with the emulsion sticking to

permanent reverine pattern on the emulsion.  The old
matte surface papers were especially prone to this problem. 

Probably I hadn't dried the paper off enough before
I put it in the blotter.  My usual procedure was to blot
the paper dry between bath towels and then place it in the
blotter.  Now my procedure involves an Arkay drier ...

I'm not sure what this material is, it looks something like Glassine. I've found that it has a limited lifetime before it gets wrinkled. There is probably some better material to use. If the paper sticks to it the effect is something like ferrotyping and, as you say, any wrinkles in the paper get molded into the emulsion. I don't think there is anything that can be done about wrinkled "wax" paper other than to replace it. I think the amount of hardening of the paper may have some effect on this whole problem. Its possible that the use of a hardening fixer and an after treatment which does not destroy the hardening may help. Kodak Hypo Clearing Agent has the right pH to maintain the hardening but still release bound up hypo.
