This is a test of the ACRYLITE RP materials that are offered by Evonik (Germany) for Rear Projection acrylic screens.
My favorite is the 7D006, but since it is hard to get if you live outside of Europe, of the other materials, which are domestic USA mainly, the dark grey had the best and closest image quality to the 7D006.
7D006 - grey (Used in the Microsoft Surface Tables)
0D002 - colorless
7D512 - light grey
7D513 - dark grey
Projector: 2500 lumens
Ambient Light: Medium
