Harkness Matt Preview screens are used in preview theatres and in small theatres where seating positions are close to the screen and the projector power is relatively high, generally in dark conditions. The flexible PVC-based material is manufactured to a unique formulation and specification providing wide viewing angles, high contrast, bright pictures and excellent colour temperature. Our proprietary and unique seam welding process ensures our screens have no visible seams under projection conditions. Screens are available in either perforated or non perforated forms depending on speaker placement. Matt Preview screens are not foldable and all must be rolled for transportation.
