I've been using this stainless steel flashing that is typically used for roofing. You can get 20in wide rolls in stainless or aluminum at home depot / most building supply stores for pretty cheap and it has worked well to keep the top and bottom of my boards flat and wrinkle free.

I use a sheet of 1/8" thick Lexan (polycarbonate). Ski tops come out smooth as silk everytime.

I have a cold press and I use a layer of peel ply under a layer of about 2mm thick white plastic shower liner (from home depot). This method leaves a peel ply texture on my veneer topsheets that is easy to sand off.
I have some 2mm thick rubber that I want to use with an aluminum sheet when I switch to a heated press.
