  • Patent number: 6220693
    Abstract: The present invention relates to a method and apparatus for printing digital color images with non-impact print heads whereby fluid flowing at a relatively high velocity proximate ink emitting nozzles affects flight trajectories of undesirable satellite ink droplets incidentally emitted from the nozzles, but does not affect flight trajectories of primary droplets. In one embodiment, a single fluid deflector member oriented upstream of the print head causes fluid flow intermediate the print head and the printing surface and urges the satellites to a preferred location on the printing media. In another embodiment, at least one additional deflector member is oriented to cooperate with the deflector member to ensure that such satellites encounter a forced fluid flow intermediate the print head and print surface.

  • Patent number: 5797186
    Abstract: A method for manufacturing an imaging drum for use in applying ink to the imaging drum as the drum rotates. The present method possesses utility in that previously unsuitable low cost materials for use in creating an imaging drum characterized by rigorous specification and tolerance requirements adequately perform when manufactured in accordance with the present method. The present method finds use in the digital printing and imaging industry where successful repeatable and accurate printing requires precise knowledge of the characteristics of the print engine mechanical motion and printing materials which include printing media (e.g., paper, vinyl, film, wax or other thermally imaged substrates that typically include emulsion coatings thereon) to promote consistent interaction with printing media marking materials such as ink, toner, or various printing ribbon resin-based compounds, etc.
