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.
Screens are perforated to facilitate the acoustic performance of behind-screen speakers. For most cinema auditoria, standard perf pattern is used. For close viewing (less than 5m/16ft), Mini-Perf (MP) products such as Matt Preview Mini-Perf (MP) are recommended. It has smaller diameter perforations (less than half the diameter of other Harkness projection surfaces) to provide the ultimate surface type for close viewing conditions.
Non-perforated screens are available for use when there are no speakers situated behind the screen.

Screens should normally be transported and stored at temperatures between 5°C and 30°C (40°F and 85°F), with relative humidity less than 80%. If screens are very cold (e.g. following air transport) then they must be allowed to warm up before unpacking, otherwise cold cracking may occur. Screens should be installed within a maximum of 2 months of shipping. Packages should be handled with care to avoid damage.
The general environment where the screen is installed should be kept reasonably clean to avoid dirt and dust build-up. Screens can be periodically cleaned using a soft brush or cloth, doing this vertically with limited pressure. Under no circumstances should the screens be made wet or cleaned with any material containing bleach or other chemicals. Harkness Screens is not liable for damage caused to screens through the use of inappropriate cleaning methods or chemicals.
