Abstract:
The invention relates to reflective and non-reflective features formed from multiple inks. In one embodiment, the printed feature comprises a substrate having a first region and a second region, the first and second regions having different surface characteristics; a first printed element disposed on the first region; and a second printed element disposed on the second region, wherein the first printed element is more adherent than the second printed element to the first region. In another embodiment, the printed feature comprises multiple layers formed from different inks exhibiting enhanced durability. The invention is also to processes for forming these features, preferably through a direct write printing process.
Abstract:
The invention relates to different methods for distortion-free production of data carriers having at least in partial areas a transparent plastic layer with a surface structure in the form of a lens structure. The surface structure can be produced by cutting methods or embossed by applying heat and pressure. Alternatively the surface structure can be produced as a separate element which is connected after its production with the data carrier.
Abstract:
A protective layer transfer sheet, including a heat-resistant layer provided on one surface of a substrate film, and an adhesive layer, a releasable protective layer, and a heat seal layer laminated in this order on the other surface of the substrate film.
Abstract:
A method of assembly and activation of a reusable self-expiring Security Identification Badge is provided. The Badge includes a base substrate having a void indicia area. Also included is an ink substrate having an expired indicia area of a soluble ink and an adhesive surface. Also included is an overlay substrate having an ink dissolver and a display surface. When the Security I.D. Badge is issued, the inked substrate is attached to the base substrate, the inked substrate covering the void indicia area. The overlay substrate is then placed over and attached to the inked substrate, the ink dissolver in contact with the soluble ink of the ink substrate. The ink dissolver of the overlay substrate contacts and coacts with the soluble ink of the inked substrate to dissolve the ink and allow the ink to migrate through to the overlay substrate to the display surface, where it can be visually perceived, in a preselected time interval.
Abstract:
The invention is a document security system characterized by a data substrate having photographic or printed information on a base print, and also having a personalized polarization-altering overlay sealed to the base print and encoded with additional coded information readable under the influence of a polarizing viewer. The low-security information, such as name, social security, account number and photograph, are printed on a card to form the base print. Additional information of greater security, which may be a bar code or alphanumeric characters, is imprinted in the polarization-altering overlay by an appropriate physical process, such as radiation exposure or thermal, chemical or mechanical treatment, which optically modifies localized regions of the overlay. Tampering with the card, which will require removing and physically modifying the overlay, altering the base print information, and resealing the overlay, will create optical errors which become evident when the tampered document is viewed through the polarizing viewer. The invention provides an security document system with tamper-resistant and tamper-evident features that are easy to detect and difficult to imitate, the document also being long-lasting and cost-effective to produce and use. The invention is applicable to identification documents such as drivers' licenses, passports and immigration cards, and also to monetary instruments such as credit cards, stock and bond certificates, and currency notes.
Abstract:
The image receiving medium of the present invention is an image receiving medium to be used in combination with a heat transfer sheet, characterized in that the image receiving medium includes a laminate of at least one polyvinyl chloride resin sheet, and at least a layer of the image receiving medium superposed on the heat transfer sheet which receives the dye from the heat transfer sheet includes a polyvinyl chloride resin composition containing 0.1 to 10 parts by weight of a plasticizer based on 100 parts by weight of the polyvinyl chloride resin. The image receiving medium of the present invention has specific features in that no image receiving layer is required to be provided separately, image formation of a picture and the like according to the heat transfer system can be effected sharply and quickly, and yet curling caused by heat transfer is not generated.
Abstract:
An optical card comprising a card substrate and a light reflective layer provided on said card substrate, said light reflective layer comprising an optical reflective metallic thin film having a light information pattern formed therein is prepared by forming said optical information pattern by photoetching. According to this optical card, it is possible to readily carry out high density recording.
Abstract:
The multilayer identification card comprises several synthetic layers compounded by the effects of heat and pressure. An inside interface of at least one of these layers exhibits depressions which are filled with the material of the adjacent layer during the laminating process. The adjacent layers are selected in such a way that they are of different transparency. Thus a light and shadow effect is produced in incident light which is reversed in transmitted light.
