  • Publication number: 20080272587
    Abstract: A security feature for an identification document and method for making it provide layers of security, including, for example, tamper evidence, optically variable effects, and personalized information that links the security information to the document and its bearer. The feature is made by printing a first material representing first information on a core layer of the document. This first material at least partially overlaps the core layer. One example is Xerographic printing of information about the ID document applicant and the applicant's photo. The process also applies a second material representing second information adjacent to the first material. One example is ink jet printing of personal information with a UV curable ink in the form of a relief pattern on the core layer. Finally, the process applies a laminate layer over the core layer. The laminate layer covers the first and second materials.

  • Publication number: 20080128493
    Abstract: A laser markable document material comprises a binder sensitive to laser energy, a pigment interspersed in the binder, and a document substrate. One example of the pigment is a pearlescent silicate, which has optically varying effects. The binder is applied to the document substrate using a form of printing or other means of applying a coating. This coating provides a first indicia of fixed or variable information, such as the seal of the document issuer or personal information of a document bearer. A laser engraver writes a second indicia into the coating.

  • Publication number: 20070166519
    Abstract: A security feature for an identification document comprises a base document layer, including a first image printed with a covert ink, and a personalized image relating to a bearer of the document (such as a facial photo) printed over the first image. The personalized image is printed with an ink that is incompatible with the covert ink such that the first image becomes overt within the personalized image upon printing of the personalized image. This feature creates an interlocking relationship between the covert image, which may be pre-printed prior to personalization on card stock, and personalized information printed over the covert image. Variations of this feature can be made in which the first image is not covert, yet still creates an interlocking relationship due to ink incompatibilities. Further, the second image may depict information other than personal information.

  • Publication number: 20070102920
    Abstract: A forensic feature for a secure document comprises a base document layer and a covert material applied to the base document layer. The covert material includes a carrier and forensic material within the carrier. The forensic material includes a ratio of salts or oxides of metals, such as rare earth metals. The ratio is selected to correspond with a source of the document. The forensic material may be mixed into a coating or ink that is applied at predetermined locations on a secure document. The ratio is then measurable from metal ion signals of the salts or oxides. This ratio, or some metric derived from it, may be linked with information embedded elsewhere in the document to enable verification of the document. Another forensic document feature has a forensic metric that is measurable from a covert material in the document, and this forensic metric corresponds to a source of the document.

  • Publication number: 20060228530
    Abstract: An image destruct material comprises a release layer positioned between an image receiving layer and a base layer. The adhesion between the release layer and the base layer is greater than adhesion between the release layer and the image receiving layer. The release layer material can be used in secure documents that have an image receiving layer, such as used for dye diffusion, mass transfer, ink jet, and xerographic printing. For example, particular implementations are designed for identification documents with a D2T2 image receiving layer. In these implementations, for example, the release layer is in the form of a patterned coating under the image receiving layer. After information is printed on the image receiving layer, an overlaminate is applied over it.

  • Publication number: 20050255280
    Abstract: The invention provides hard coat and image receiving layer structures and related methods used in ID document production. These structures and methods provide ID documents that offer hard protection in areas where needed (e.g., in optical windows for machine readable data), and also provide image receiving layers for later printing of variable data, such as personalization information of the bearer. Implementations of the structure provide an effective interface between hard coat and image receiving layers that provides enhanced durability in manufacture and field use.

  • Publication number: 20050247794
    Abstract: An identification document is provided, comprising a core layer, such as TESLIN, laminated directly to a laminate layer, such as polycarbonate, without the use of an adhesive. The core layer has at least one indicium formed thereon and has a first surface. The first layer of laminate is affixed to the core layer by a press lamination process where the press lamination process is sufficient to couple the core layer to the first layer such that an attempt to separate the first layer from the core layer causes at least a partial destruction of the core layer.

  • Publication number: 20050161512
    Abstract: The invention relates to identification documents, and in particular to providing optically variable personalized data to identification documents. In one implementation, we provide an identification document comprising a document layer and a first indicium. The document layer comprises a material capable of being printed by a thermally transferable optically variable ink. The first indicium is printed on the document layer and comprises personalized data and printed to the document layer by a thermally transferred optically variable ink. The first indicium may be printed to the document layer by disposing a thermally transferable optically variable ink in a mass transfer panel of a printer ribbon adapted for use in a dye diffusion thermal transfer printer, and printing the first indicium as part of a mass transfer printing process.

  • Publication number: 20050042396
    Abstract: The present invention relates to assembling identification documents in an over-the-counter issuing environment. In one implementation of the present invention, we provide an identification document capable of being printed by an ink jet printer-based system in an over-the-counter environment. The identification document comprises a core layer and a first indicium. The core layer has a first surface, and the first indicium is printed directly onto at the first surface of the core layer. The first indicium is formed by a pigmented ink jet ink. The core material can have an affinity for a particular substance (e.g., water) and the pigmented jet ink can include that substance (e.g., an aqueous-based ink jet ink). An identification document substrate can receive pigmented ink jet ink from an ink jet printer without requiring a receiver layer or receiver coating on the substrate.
