One way vision, also called perforated foil, which can be digitally printed, is a type of advertising material applied to building windows.

The best part of the one way vision application is that the outside can be seen clearly when viewed from the inside. When viewed from the outside, if the interior is dark, the interior is not visible. After dark, the interior begins to be seen with the use of lighting in the interior. In other words, it acts both as a curtain and as an advertisement. For this reason, it is a very advantageous application for businesses on the street.
