Window graphics, window decals or window film provide privacy as well as a branding and promotional platform. These applications can be opaque, frosted or semi-transparent and can be applied both internally and externally.  Window graphics consist of large areas of glass covered by a single, full-colour, custom print.   Window decals, on the other hand, are made up of smaller, printed, cut-out shapes and letters applied to part of a window. Window film is yet another option, also known as Window vision or Contravision.  This widow treatment uses a perforated film which allows light in and is see-through from inside, but not from the outside.
