  • Patent number: 4759982
    Abstract: A process for preparing a transfer graphic article having a protective clear coat in precise registration therewith such that the graphic has rounded and sealed edges, and the article produced thereby. The edges of the underlying adhesive are sealed by the clear coat such that improved solvent resistance is achieved.
    Type: Grant

  • Patent number: 4735827
    Abstract: A process for preparing a graphic pattern on a carrier having a protective coating thereon in exact registration with the pattern, and the article produced thereby. The process comprises applying a liquid protective coating over the graphic pattern slightly beyond the edge definition of the pattern and in substantial registration therewith, the protective coating having sufficient surface tension to wet the graphic pattern, but not the surface of the carrier. When the protective coating is dried, it dewets and retracts from the surface of the carrier onto the graphic pattern and provides exact registration therewith.

  • Patent number: 4135813
    Abstract: A camera for photosensitive material used in producing half tones wherein a device for flash exposing the image to create better half tones is afforded by the use of a low wattage lamp projecting light along the optical path of the lens from the shutter, through a screen and onto the film plane for the photosensitive materials. The light is so directed by a specular reflective surface on the back of the shutter and a lamp off axis directing light to the reflective surface. Timing for the flash exposure is provided by commercial circuitry.
