    摘要： A security device includes an image projection system that includes an array of focusing elements (101) and an array of image icon elements (103) disposed relative to each other such that a synthetic image is projected by the image projection system. This synthetic image, along with at least one other image functions as a targeting image. As targeting images (310′, 310″), these images are spatially coordinated such that a reward image (350), which is otherwise at least partially hidden, becomes revealed upon the targeting images having a predetermined transformation. This targeting effect functions as a game that attracts the attention of an end-user of high-valued articles of manufacture to which the security device is attached. The security device allows a viewer to actively interact with the security device by trying to turn on the reward image.

    摘要： A security element including: a first layer having a first surface; an array of image regions across the first surface arranged along at least a second direction, each region including at least a first image sub-region having an average inclination defining an angle, relative to a plane of the security element, about an image region axis extending along a first direction; a diffractive optically variable effect generating structure provided in or on the first surface across the first image sub-regions, the structure including diffractive elements that extend along a direction within 45° of the first direction, wherein the structure is provided across the first image sub-regions and spatially arranged and/or modulated across the first image sub-regions in accordance with a first image so the first image is displayed by the first image sub-regions in combination at least at a first viewing angle. Also, a method of manufacturing the security element.

    摘要： Provided is a laminated body in which a print layer is provided downstream of a laser color development layer without lowering quality. A card is provided with an offset print layer laminated on a base material, a buffer layer laminated on the offset print layer and having translucency, and a laser color development layer laminated on the buffer layer. The buffer layer minimizes scratches on the offset print layer that occur with the heat generation of the laser color development layer.

    摘要： A multilayered printed matter is made up of a plurality of layers formed on a medium, including a front layer and a back layer with patterns printed thereon, and a white layer and a black layer interposed between the front layer and the back layer so as to conceal the back layer to be invisible from the front-layer side. The system for producing the multilayered printed matter includes a computer that executes a printing step of moving the medium and an inkjet head relative to each other using a moving device and printing the front, back, white, and black layers on the medium using the inkjet head, and a cutting step, subsequent to the printing step, of moving the medium and a cutting blade relative to each other using the moving device and cutting the medium using the cutting blade.

    摘要： The present invention relates generally to a data carrier and a method for making the data carrier. More particularly, this invention relates to color laser marking of article, especially security documents. The present invention proposes a security document comprising a multilayers assembly instead of a single color component mixture in a layer. The multilayer assembly comprises at least two laser sensitive layer. Each layer comprises at least one coloring agent component. The order arrangement of the multilayers of bleachable coloring agent component is made so that each layer behaves as a wavelength filter configured to selectively transmit longer wavelengths and block or attenuate shorter wavelengths while protecting the underneath coloring agent component from bleaching interference.

    摘要： A secure multilayer structure, in particular for a secure document, including a base layer, at least one masking layer including a window opened in the masking layer, the window having an edge, a security element including a photoluminescent agent positioned between the base layer and the masking layer, adjacent to the window edge, such that the presence of the agent can be checked by illuminating the edge of the window and viewing the re-radiated luminescent light emerging from the masking layer through the window edge.
