Mech is of flexible design. It can be designed for front or back projection, the more common being front projection systems, which have the image source situated on the same side of the screen as the audience.
The design of Mech follows a set of criteria. All criteria are developed from a lifecycle perspective of the screen, covering manufacturing, use, and end of life or recovery phases.
The materials used for Mech are certified by the Imaging Science Foundation (ISF) for its compliance with the standards of HDTV product video performance engineered for Calibration.
Mech uses a professional grade projection screen material. This kind of material is formulated with a 300D technology core and is suitable for roller retractable application.
Mech is manufactured from a highly durable screen material. This kind of material is specially designed for both indoor and outdoor use.
This product has electromagnetic compatibility. EMC testings are performed in it manufacturing to a wide range of EMC standards such as EMC Directive 2014/30/EU.
