Customers often ask, does one-way window film work at night? While conventional white on black perforated window graphics suffer from “burn-through” at night when the inside is illuminated. This occurs when there is not enough external light to properly illuminate the graphics and they are overpowered by interior lighting, so the graphics fade and become see-through. Contra Vision® Performance Translucent White™ backlit film provides a solution for achieving 24/7 perforated window graphics but careful consideration needs to be given to the back lighting to get the best see-through window graphics.
Ambient lighting from inside a building is enough to provide some illumination of the graphics. The light transmits through the translucent material of the perforated window film to brighten the printed image. This effect can be enhanced by removing point sources of light from directly behind the window and adding spot or flood lights from outside the field of vision. Even if the internal lighting is sub-optimal, the night-time visibility of the window graphics will still be better than with conventional perforated window film.
The daytime view out through Performance Translucent White backlit film print is still remarkably good and natural light is allowed into the building. The eye will tend to focus on the outside view and ignore the ghost image of the print that is visible on the inside of the film. In some settings the ghost image has been used as a design feature to enhance interior décor.
