  • Inspection Device And Method
    Publication number: 20160178535
    Abstract: An inspection device including an illumination source emitting illumination that is divided into lighter and darker bands; a viewing system placed a first distance from the illumination source; a material to be evaluated placed a second intermediate distance between the illumination source and the viewing system on an imaginary line connecting the viewing system and at least some portion of the source of illumination. An inspection process including placing a material to be evaluated between an illumination source emitting illumination that is divided into lighter and darker bands and a viewing system placed a first distance from the illumination source; wherein the material to be evaluated is placed at a second intermediate distance between the illumination source and the viewing system, and on an imaginary line connecting the viewing system and illumination source; illuminating the material; and evaluating the material with the viewing system.

  • Method to reduce surface resistivity of a release agent applicator in a printing apparatus
    Patent number: 9221244
    Abstract: A release agent applicator displaying decreased and consistent surface resistivity, and a method of making same. The release agent applicator includes an foam delivery surface having an ionic layer such that the surface resistivity of the delivery surface is reduced, thereby decreasing the chances of static charge accumulation on the roller that may interfere with high quality printing.
