Abstract:
A security device including an array of lines printed or otherwise provided on a substrate, the lines including materials which have the same appearance under visible light illumination but which appear different from each other in the visible under a combination of visible and non-visible, ultraviolet illumination. At least some of the lines in the array appear different from other lines under the combination of visible and non-visible, ultraviolet illumination. A second, surface relief array of lines imposed on the first array, the orientation, line widths and spacings of the first and second arrays being such that the device exhibits a variable appearance as it is tilted while exposed to the combination of visible and non-visible illumination.
Abstract:
There is described a printed security feature (1) provided onto a printable substrate, which security feature includes a printed area (100) consisting of a multiplicity of adjacent rectilinear and/or curvilinear elements (110, 120) printed with a given spatial frequency. The rectilinear and/or curvilinear elements are printed with at least first and second inks which exhibit the same or substantially the same optical appearance when illuminated with visible white light, such that the security feature produces a first graphical representation when illuminated with visible white light, at least the first ink being an ink which responds to non-visible light excitation by producing a characteristic optical response differentiating the first ink from the second ink. The security feature produces a second graphical representation when illuminated with non-visible light, which second graphical representation exhibits a distinctive two-dimensional graphic element (B) which is revealed only when the security feature is illuminated with non-visible light. Inside boundaries (160) of the distinctive two-dimensional graphic element, a part (P3) of the rectilinear and/or curvilinear elements is printed with a combination of the first and second inks, the rectilinear and/or curvilinear elements being subdivided, within that part, into first and second juxtaposed sections (110a, 110b, 120a, 120b) which are respectively printed with the first ink and with the second ink. Outside the boundaries of the distinctive two-dimensional graphic element, portions (P1, P2) of the rectilinear and/or curvilinear elements are printed with only one of the at least first and second inks. The at least first and second inks are printed in register one with respect to the other so that the boundaries of the distinctive two-dimensional graphic element are not visible when the security feature is illuminated with visible white light and the distinctive two-dimensional graphic element only becomes visible when the security feature is illuminated with non-visible light.
Abstract:
A method and security device, including: a semi-transparent layer exhibiting a first pattern of regions having high optical density and/or raised surface profile relative to layer intervening regions; and a color layer exhibiting a second pattern of elements of at least one color. First and second patterns partially overlap and are configured so the device, appearance varies at different viewing angles. First pattern has color layer following the contours of raised regions. Security device includes: a photosensitive film exhibiting pattern of regions of relatively high and low optical density, the pattern arising from photosensitive film exposure to radiation of a responsive predetermined wavelength from the photosensitive film; and a color layer overlapping the pattern exhibited by photosensitive film, which exhibits increase in optical density upon radiation exposure of a predetermined wavelength and concurrent or subsequent heating. Increases in optical density being due to the bubbles formation within the photosensitive film.
Abstract:
An optically variable surface pattern is made available, having at least two partial areas with reflection elements, wherein the reflection elements of the first partial region on the one hand and the reflection elements of the second partial region on the other hand reflect impinging light in different reflection directions. The first partial region is so covered with a first glazing ink layer that a viewer, upon a change of the viewing angle at which the viewer views the optically variable surface pattern, sees the first partial region glow in a first color upon reaching a first viewing angle. The second partial region glows in a second color that is different from the first color upon reaching a second viewing angle.

Abstract:
A verifiable/copy-protected document features a combination of nearly identical line-screen patterns for embedding latent images within visually integrated settings. The latent images can be detected for purposes of verification with a matching viewer but are indistinguishable from their visually integrated settings under ordinary viewing conditions. The line-screen patterns, which can be incorporated into document artwork, are printed at certain combinations of line frequencies and print densities so that the line-screen patterns digitally reproduce as a largely undifferentiated solid tint.
Abstract:
A transaction card package assembly comprising a transaction card connected to a first panel via a releasable interface, wherein the first panel is affixed to a second panel such that upon releasing the interface, the first panel remains affixed to the second panel and the transaction card is released from the package assembly.
Abstract:
A stored value card having increased theft prevention features. A large format sheet having a plurality of cards is imaged with variable indicia. A tamper proof layer is applied over the barcode such that if removed, the variable indicia would no longer be readable. Alternatively, unique human readable indicia is imaged on the substrate and then encapsulated by the tamper proof layer. The sheet is then imaged with a barcode or encoded with a magnetic stripe, simultaneously linking unique human readable indicia to the card. An alphanumeric code matching the unique indicia is displayed at the time of activation to authenticate the card. In either embodiment, the sheet is imaged in large or full format without the need for reducing the size of the sheet.
Abstract:
This invention provides a latent image pattern formed body that allows to observe a latent image having excellent visibility and authenticity discrimination and design properties than those of related arts when observed from the oblique direction. The latent image pattern formed body includes, in at least part of one surface of a substrate, a latent image region, an outline region arranged on an outline of at least part of the latent image region, and a background region arranged on a background of the latent image region and the outline region. In the latent image region, a plurality of first elements having a concave or convex shape are arranged at a first pitch in a first direction. In the background region, the plurality of first elements are arranged at the first pitch in the first direction in a phase different from that of the first elements in the latent image region. In the outline region, the plurality of first elements are arranged at the first pitch in the first direction in a phase different from that of the first elements in the latent image region or background region adjacent to the outline region. In the latent image region, the background region, and the outline region, a plurality of second elements having a color different from that of the substrate are arranged at a second pitch in a second direction.
Abstract:
Method and apparatus for applying unique composite indicia or markings to a succession of articles, in which each unique composite indicium comprises two or more indicia. At least part of each of the indicia may be co-located at a predetermined location on the article with such co-location being unique or distinct for each composite indicium for each article. The indicium may be overprinted with one or more images, logos or color-schemes. A code (e.g. an alphanumeric string) that is stored in a database may be derived from the composite indicium from one or more mathematical properties. The code may be later accessed for identifying or verifying the article with the indicium.
