Our products transform glass surfaces, enabling graphics and advertising messages to be visible from one side but not the other side, which remains see-through. In effect Contra Vision can turn any area of glass into an advertising or promotional opportunity.
In its most common form, Contra Vision is applied to windows as a self-adhesive film. A graphic is printed on one side using a perforated hole, dot or line print pattern, with gaps inbetween keeping up to fifty percent of the surface as see-through. The graphic is not seen from the other side because a layer of black is used to completely obscure the ink pattern, but not the areas of see-through.
When looking at the side with graphics, the eye is drawn to the printed colours because they reflect more light than passes through the gaps in the ink patterns. From the other side, the view through the film is dominant because the black layer absorbs light.
