  • Method for making translucent colored-backed films and continuous length made thereby
    Patent number: 5667618
    Abstract: A method is described for making colored backed film material using a polyvinyl fluoride (PVF) film having a first face and a second face opposite the first face. The method comprises the steps of coating the first face of the PVF film with an ink-receptive coating. A carrier is then statically laminated to the second face of the PVF film. Using a rotary web printing apparatus, an acrylic ink is then continuously applied onto the first face of the PVF film. After drying the ink, the PVF film is separated from the carrier and the colored PVF film is coated with a pressure-sensitive adhesive and provided with a release paper.
