  • Patent number: 8343611
    Abstract: A one-way vision film includes a white film base material; a shrinkable color tone layer on one side of the base material; and a self-adsorptive foamed layer on the base material opposite to the shrinkable color tone layer. The one-way vision film is perforated with through-holes. The self-adsorptive foamed layer has an adhesive function attachable to a surface onto which the film is attached and is printable. Since the printing ink is deposited to the bottoms of the open pores while not closing the openings of the open pores, open pores exposed to the surface of the foamed layer function like suction cups adhering onto a smooth surface. Accordingly, there is no need for forming ink-receptive and pressure-sensitive layers, unlike a conventional film, so the film can have a low cost, three-layer structure. The one-way vision and printed film is easily attachable onto a smooth and transparent substrate like glass.

  • Patent number: 5272972
    Abstract: An inking and doctoring arrangement for a pad printing press includes a unidirectionally rotatable replaceable flat printing plate, a doctor blade arranged above the printing plate and displaceable relative thereto for scraping ink from the upper surface of the printing plate, and an ink tray for fixedly receiving the printing plate.A tray cover is rotatably supported on the ink tray above the printing plate for preventing evaporation of the ink thinner. An ink guide is fixedly secured to the tray cover for joint rotation therewith for spreading ink scrapped by the doctor blade over the upper surface of the printing plate while kneading the same.
