  • Patent number: 10112434
    Abstract: A security document created by laminating a metalized foil between transparent layers, and modifying the outside of the foil to form a base color of the document, while leaving a window area formed by an unmodified portion of the foil. A laser is then used to ablate at least a portion of the unmodified portion of the foil in the window area to create an image. The window area includes the laser ablated image formed therein. The resulting image is transparent, with the image being visible from a front of the security document and visible from a rear of the security document.

  • Patent number: 8511712
    Abstract: Pigment flakes are blended together wherein some are magnetically alignable and exhibit a color shift from a first color to a second color with a change in viewing angle; and some are pigment flakes which exhibit a color shift from the first color to a third color or vice versa with a change in viewing angle, wherein the first, second and third colors are three different colors. The flakes are coated upon a substrate and magnetically alignable flakes are magnetically aligned. The non-magnetically alignable flakes are not aligned by the magnetic field and lie flat upon the substrate they are coated on. By judiciously selecting the angle upon which the magnetic flakes are oriented, an effect is created whereby an observer sees a color shift from a first color to a second or a first color to a third, when orienting the substrate by tilting it at different particular angles. The coated substrate can be used in security applications such as on currency or secure instruments.

  • Patent number: 8439403
    Abstract: A printed article is disclosed having a light transmissive substrate having a reverse printed region on a surface thereof in the form of a plurality of very closely spaced printed lines or regions. The printed regions and spaces therebetween are subsequently flood coated with special effect ink such as optically variable ink wherein the ink particle size is on average greater than the gap between reverse printed regions. The image is viewed from the non-printed side of the substrate and very fine lines of the special effect flood coated special effect ink appear as very clear sharp lines having a fine resolution. This eliminates the typical jagged edges that would otherwise be seen if the inked region was not present. This effect is due to the first printed inked regions or lines forming a mask through which the flood coated ink is seen.

  • Patent number: 7744797
    Abstract: A multilayer security element with at least two security features exactly disposed to each other is produced by the security features being present on separate carrier foils (100, 200) and the carrier foils being laminated with each other in such a way that the security features in the layer compound are disposed to each other in register. As to achieve an exact register of the security features, each carrier foil has register marks, with the help of which the foils are controlled relative to each other. The controlling is effected by stretching that carrier foil, the security features of which are running behind relative to the security features of the respective other carrier foil.

    Abstract: Magnetic ink and toner compositions traditionally comprise magnetic materials in fine particulate form, either as a dry composition or a liquid suspension. Often such materials are black or dark in colour. Disclosed herein are particles compositions suitable for use as inks or toners, that exhibit desirable magnetic properties, and furthermore which include particles coated so they appear white substantially white, or coloured. Such compositions present new opportunities for the production of corresponding magnetic layers, when the compositions are deposited in an appropriate manner to a substrate.

  • Patent number: 7691468
    Abstract: The invention discloses a device and a method for transferring a predeterminable, high-resolution magnetic design onto a document printed with a magnetic ink, in particular a magnetic optically variable ink. The device comprises a body of a composite permanent-magnetic material, having at least one flat or curved surface engraved with indicia corresponding to the design to be transferred, wherein the said magnetic material is permanently magnetized, preferably in a direction substantially perpendicular to the said surface. The method comprises imprinting or coating a first surface of a sheet or web with a magnetic ink or coating composition, and approaching the imprinted sheet or web to the engraved surface of a body of magnetized composite permanent-magnetic material while the ink is wet, followed by hardening the ink.

  • Publication number: 20100052307
    Abstract: The invention relates to a security element for securing value documents which has magnetic material. Further, the invention relates to a value document, a transfer material and a method for checking such a security element or value document. Along the security element, for example along a longitudinal direction of the security element, there are disposed one or more, maximally five, magnetic areas and one or more, maximally five, gap areas. The extension of the magnetic areas or the gap areas along the security element is preferably chosen so great that the magnetic signals of adjacent magnetization steps that arise upon transport of the security element past the magnetic sensor interfere constructively with each other.

  • Publication number: 20090302595
    Abstract: The invention relates to a security strip and security paper for obtaining security documents such as legal tender notes, checks or identification documents, comprising a cellulose support web that is completely embedded in a pulp substrate. As both the substrate and the support web are formed by plant fibers, a series of physical and chemical bonds are established between the fibers of both elements, the support web thus being perfectly integrated in the pulp. The cellulose support web will sometimes have a series of security elements, such as pigments, synthetic elements and/or security fibers of the type normally used in this type of application.

    Abstract: Systems and methods for using microscopic capsules containing orientable materials for document security and processing applications are presented. A security application comprising a medium having a substrate and a plurality of microcapsules is disclosed. The microcapsules contain magnetically orientable material and a liquid. The magnetically orientable material is oriented in a first alignment. Application of a magnetic field to the medium orients the magnetically orientable material to a second alignment, thereby altering the opacity of the medium. Magnetic material may also be dragged into a concentrated arrangement by a magnetic field, thereby altering the opacity of the medium.
