Patent number: 7270929Abstract: A method and a medium for laser imaging is herein disclosed. The medium incorporates one or more types of microstructures having a predetermined heat or radiation modifiable optical characteristic such as color, scattering, diffusion, diffraction, interference and iridescence. Associated intimately with the microstructures is a radiation antenna that acts to absorb radiation from a radiation source. The radiation antenna and source are attuned to one another to efficiently transfer energy therebetween and subsequently to the microstructures; this transfer of energy results in the modification of an optical characteristic of the microstructures to form an image on the medium. The medium has one or more layers that may include both the radiation antenna and the microstructures. Alternatively, the microstructures and radiation antenna may be included in separate layers. Coatings that incorporate one or more layers that include distinct microstructures and radiation antennae are also contemplated.Type: GrantFiled: February 24, 2005Date of Patent: September 18, 2007Assignee: Hewlett-Packard Development Company, L.P.Inventors: David M Kwasny, Makarand P.

Patent number: 5744291Abstract: This disclosure concerns with a method of producing 3D print materials and the structure thereof. In the preferred embodiment of the present invention, the 3D print material consists of a lenticular screen, an image forming layer and an anti-halation layer coated on the image forming layer opposite from the lenticular screen. When the thickness of the lenticular screen reaches a certain amount, it renders the coating of an image forming layer onto the lenticular screen too difficult or impractical. With such a thickness, it is advantageous to coat the image forming layer and the anti-halation layer on a clear polymer base, and then securely attach the coated polymer base to a bare lenticular screen with the aid of a bonding layer. Similarly, a parallax barrier plate can be used in lieu of a lenticular screen for producing 3D print materials.Type: GrantFiled: April 3, 1997Date of Patent: April 28, 1998Inventor: Sunny Leong-Pang Ip

The composite sheet comprises a flexible base film having front and rear surfaces and a layer of a cured thermosetting polymer overlying the front surface of the base film. The cured thermosetting polymer layer has a nonplanar outer surface defining a predetermined desired relief pattern of high quality and durability and of fine definition in the thermosetting polymer layer.Type: GrantFiled: September 5, 1980Date of Patent: November 8, 1983Assignee: Rexham CorporationInventor: Kenneth E.

Patent number: RE38065Abstract: A process for printing an image (IC) on a lenticular lens material (12) with a printing press (10). A separate film negative (B, C, Y, M) is prepared for each color used in printing the image. One of the negatives (B) is selected and each of the other negatives, and the lens material, is registered with the selected negative. Each of negatives is adjusted to the selected negative so all of the negatives and the lens material are in registry with each other. Separate printing plates (18) are prepared from each of the negatives. The plates are mounted on the press at respective printing stations and the lens material is run through the press with each of the plates being used to print on the material. The plates are adjusted, as necessary, to align the plates and register the color dot patterns printed by each plate to the color printed by the plate made from the selected negative.Type: GrantFiled: April 6, 2001Date of Patent: April 8, 2003Assignee: Lenticular Technologies, LLCInventors: Daniel W.
