Contra Vision® Performance™ Black Perforated Film in 20% transparency is a black on black perforated film intended for the production of dual-color back-lit signage.
The film is applied to the outside surface of the built-up channel letters and during the day, when it is not backlit, the sign appears black. When the sign is backlit at night, it takes on the color of the translucent sign face used.
We recommend this film to be used for medium-term, large-scale backlit external signage where close viewing is not required. As you can see from the examples in the video, this product is most often used for store branding and other places where built-up channel letters are used.
