Publication number: 20060114530Abstract: A method of generating a variable demetallized pattern in a holographic web and a security device using such method. A holographic microstructure pattern is imparted to an oligomer disposed on a surface of a substrate. A metal layer, such as aluminum, is deposited to the holographic microstructure pattern of the substrate and then covered with a variable resist pattern. The variable demetallized pattern in the holographic web is then generated by removing the metal layer not covered by said variable resist pattern.Type: ApplicationFiled: November 3, 2005Publication date: June 1, 2006Applicant: AMERICAN BANK NOTE HOLOGRAPHICS, INC.Inventors: William Morwald, Brian Mentz

Patent number: 6659507Abstract: Tamper-apparent authenticating labels which comprise a protective film, an OVD image layer and a visually transparent ink pattern therebetween, to be applied to commercial articles. Authenticity of the label can be verified by viewing the taggant with a detector. The label reveals tampering when the film is separated from the article, causing separation of portions of the OVD under the ink. Also, methods for making tamper-apparent authenticity labels.Type: GrantFiled: April 2, 2001Date of Patent: December 9, 2003Assignee: American Bank Note Holographics, Inc.Inventor: Michael Banahan

Patent number: 6436483Abstract: A method for producing a tamper evident security holographic label and overlaminate using UV casting techniques, and a security device so produced, comprising a clear protective layer; a thin layer of clear UV cured resin cast partly onto the protective layer following a designed pattern; another layer of UV cured resin bearing a cast holographic image, wherein the bond of the holographic image layer is stronger toward the surface of the protective layer than it is toward the surface of the pattern layer; a reflective layer strongly attached to the adjacent holographic layer; and an adhesive layer bonded to the reflective layer. Such a composite product when adhered to a base substrate via the adhesive layer will show no visible security feature to the unaided eye due to the thin nature of the clear security pattern.Type: GrantFiled: January 25, 2001Date of Patent: August 20, 2002Assignee: American Bank Note Holographics, Inc.Inventors: Miklos Palmasi, Anh Nguyen, Kang Lee, Lily O'Boyle

Patent number: 6328209Abstract: The object of the present invention is to effectively enhance card security in a system using identification card or the like. The card security system comprises a card issuing apparatus 100 and a card reader 300. The card issuing apparatus 100 obtains data D and E by reading hologram 2 and barcode 3 on a card 1. Data A, B and C are input from computer 200. An encryption unit 104 generates check data EN based on data A-E. A magnetic writer 103 write the data A-E and EN on a magnetic stripe 4. The card reader 300 reads data A-E and EN from the card 1, generates check data based on the read data A-E, and determines whether or not the card is genuine by comparing the calculated check data with the read check data EN.Type: GrantFiled: February 3, 1999Date of Patent: December 11, 2001Assignee: American Bank Note Holographics, Inc.Inventor: Lily O'Boyle

Patent number: 5393099Abstract: The present invention pertains to a method of producing an anti-counterfeiting document or currency which acts and feels like existing paper currencies. The method of the present invention laminates two sheets of currency paper on each side of a thin durable substrate film, thereby forming a durable document which maintains a paper-like feel. The currency of the present invention exhibits unique and powerful anti-counterfeiting features compared to those presently available. The currency of the instant invention also lasts significantly longer than conventional "paper" money.Type: GrantFiled: May 21, 1993Date of Patent: February 28, 1995Assignee: American Bank Note Holographics, Inc.Inventor: Salvatore F.

Patent number: 5194971Abstract: Methods for generating holograms from a computer model of any object employ a combination of numerical and optical means. An illumination model and the light dispersion properties of the object are specified. The hologram is synthesized from a plurality of smaller hologram elements. Each individual element sustains a field of view of the object. The light rays from the object lying within the field of view and along the lines of sight are sampled by the computer. The sample density should not exceed the resolution limit set by the size of the hologram element. Each light ray is specified by a direction and an amplitude function. The hologram element is obtainable from a Fourier Transform fo the sampled rays. In one embodiment, optical means are employed to physically reproduce the sampled light rays using coherent radiation. The reproduced coherent light rays are then interfered with a coherent reference beam to form the hologram element.Type: GrantFiled: November 6, 1990Date of Patent: March 16, 1993Assignee: American Bank Note Holographics, Inc.Inventor: Kenneth A.

Patent number: 5116548Abstract: A method and system for replicating microstructures surface relief patterns, such as diffraction patterns including holograms, by casting. A liquid casting resin is held between a surface relief master of the microstructure to be replicated and a substrate while the resin is hardened by actinic radiation curing. Application of resin to edges and discontinuities of the master is avoided in order to reduce undesirable build-up of resin on these areas of the master. The hardened resin surface relief replica may optionally be coated with a discontinuous graphical pattern of a clear or colored paint that eliminates the effect of the surface relief pattern in the regions so coated.Type: GrantFiled: June 22, 1990Date of Patent: May 26, 1992Assignee: American Bank Note Holographics, Inc.Inventors: Donald W. Mallik, Salvatore F. D'Amato

Patent number: 5071597Abstract: A technique for forming a mold to replicate large numbers of plastic articles, such as by injection or blow molding, wherein the mold contains a hologram or other microstructure for transfer to an outside surface of the molded article. The mold is made by electrodepositing a metal on a model of the article to be molded. Before this deposition, the hologram or other microstructure is formed on a surface area of the model by any one of several techniques. The result is a unitary mold piece in the shape of the article and having the hologram or other microstructure integrally formed on its inside surface.Type: GrantFiled: September 27, 1989Date of Patent: December 10, 1991Assignee: American Bank Note Holographics, Inc.Inventors: Salvatore F.

Patent number: 5044707Abstract: Non-continuous reflective hologram or diffraction grating devices are provided in various forms for authenticating documents and things, such as those that contain visual information desired to be protected from alteration. Examples of such information include written personal data and photograph on a passport, driver's license, identity card, transportation pass, and the like. The reflective discontinuous hologram or diffraction device is formed in a pattern that both permits viewing the protected information through it and the viewing of an authenticating image or other light pattern reconstructed from it in reflection. The same master hologram or diffraction grating is made into distinct authentication devices by forming replicas thereof that have different patterns of reflective material which form distinct indicia, such as a different alpha-numeric character.Type: GrantFiled: January 25, 1990Date of Patent: September 3, 1991Assignee: American Bank Note Holographics, Inc.Inventor: Donald W.

Patent number: 4921319Abstract: A replica hologram structure wherein an information carrying relief pattern on one surface of the hologram is not metallized for reflection, as is the usual case, but rather air between the hologram and a supporting substrate causes incident light to be reflected from the surface relief pattern, thereby to form a reconstruction of an image or other light pattern. The surface relief pattern may be positioned immediately against the substrate, or, alternatively, held apart from it by spacers. The hologram and substrate are held together by any of a wide variety of mechanisms, including adhesive, welding and static electricity, in a manner that does not interfere with the reconstruction or viewing of the image or other light pattern from the hologram. Such a hologram structure has a use in product packaging and other applications where it is desired to be able to look through the hologram as well as be able to view the image or other light pattern reconstructed from it by reflection.Type: GrantFiled: January 23, 1989Date of Patent: May 1, 1990Assignee: American Bank Note Holographics, Inc.Inventor: Donald W.
