Internal Perforated window film products transform glass with one-way vision graphics which cannot be seen from the other side. The graphics are used for advertising, branding or to achieve decorative effects. These films  provide privacy and solar control benefits to people inside buildings and vehicles without blocking their view outside. This product is for applying internally to the window.

How does perforated window film work?

The internal perforated window film effect is most commonly achieved by applying a self adhesive window film to the inside of the glass. The film contains areas of printed graphic (a print pattern) as well as unprinted see-through areas covering up tom 80% of the film. When looking at the side with graphics, the eye is drawn to the printed colours as they reflect more light than passes through the see-through areas (provided the lighting on the outside is brighter than the inside). The secret behind the one-way vision effect is ensuring the printed graphics are obscured or hidden from the other side of the glass. This is best achieved by having a black "backing" which covers exactly all the printed areas on the film without blocking the see-through (unprinted) areas. We achieve this on our Durst P10 250 HS+ printer by printing 3 layers. 1st layer is the image reversed on to the film, 2nd layer is pure white ink giving opacity to the printed image below and the 3rd layer is pure black ink which gives better vision from the inside looking out. When looking through the reverse side of the film, the view coming through the film is dominant because the black layer absorbs light and is less apparent to the eye.
