Plastic screens These Plastic Screens have still greater diffusion than ground glass types, allowing an image to be back-projected on a large screen without `hot spot’, and have a grey tint to minimise reflection of ambient and scattered light. The 0.3mm PVC material, with a gain of 2.3, is normally stretched over a rigid frame, where as the 3mmm acrylic (with gain of 3) is self-supporting.
