Expensive raw cards

Screwdowns are okay but you can't tighten the screws. On thicker cards as you tighten the screws the card is pushed away from the pressure and towards the center. Then when you tighten the other end the card again gets pushed towards the center but this time it has no where to go but bow, bend, or crease. Sometimes right away and sometimes when its had enough.

Too much pressure on corners can also cause the surface of come cards to glue to the screwdown probably with the help of nasty chemicals soaked up like a sponge by the card torqued down.

If screwdown is used card should be put in archival mount with a minimal amount of pressure applied to hold card put.
