  • Patent number: 8472095
    Abstract: A method for producing true three dimension imagery includes positioning an object to be imaged and directing imaging laser beams to impinge upon the object. Splitting the imaging laser beams after the imaging laser beams have impinged upon the object is then accomplished, while redirecting the split imaging beams to a recording substrate.
    Type: Grant

  • Patent number: 6458449
    Abstract: An ink jet printable coating for holographic paper is presented. The coating utilizes a high dyne primer layer and a secondary layer. The secondary layer includes a plurality of microscopic pores which are preferably 1 to 6 microns in diameter. The pores are sized to allow ink jet ink to penetrate during the printing process. The coating is compatible to both water based and solvent based inks. The pores serve to provide a site to which the ink jet ink can anchor and set, thus preventing the ink from running when initially applied to the surface and speeding the rate of ink drying. Additionally, the secondary layer is porous enough to absorb the ink as it dries. The deeper the secondary layer, the further to ink can penetrate for greater adhesion to the surface and for faster drying.
