This is CineWhite Screen Material for a 73 x 135″ HDTV Format Projection Screen from Elite Screens. CineWhite features broad light dispersion, good black and white contrast, true color rendition and a 160° viewing angle. This multi-layered, flat, mildew-resistant textured PVC surface works best with high contrast projectors and produces an evenly diffused edge-to-edge image. The black backing minimizes any chance of bleed-through. Should it become soiled, it can be washed with mild soap and water using a cotton cloth.
