This is CineWhite Screen Material for 108 x 144" HDTV Format QuickStand 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 and mildew-resistant 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.
