摘要： The invention relates to a process for securing an identification document and to a secure identification document. More particularly, the process uses UV sensitive ink(s) to define a pattern only visible under UV radiations, by printing a first layer of a transparent ablation varnish (13), printing a layer (14) of UV sensitive ink(s) over said first layer of transparent ablation varnish, removing parts of the layer (14) of UV sensitive ink(s), by means of a laser beam, some remaining areas of said UV sensitive ink(s) defining said pattern to be revealed in color under UV radiations, and some areas, where the UV sensitive ink(s) has been removed and the laser beam has interacted with the ablation varnish (13), absorbing the UV radiations with effect of creating black color. Other systems and methods are disclosed.

摘要： The invention relates to a method for producing a multi-layer body, in particular a security element, in which a partial first layer or partial first layer system is produced on a substrate, wherein the partial first layer or partial first layer system is present in a first partial area and not in a second partial area. Subsequently, a partial second layer or partial second layer system is produced, wherein the partial second layer or partial second layer system is present in a third partial area and not in a fourth partial area, and wherein the third partial area overlaps with the first and second partial areas. Finally, the partial first layer or partial first layer system is structured as a mask using the partial second layer or partial second layer system.

摘要： The invention relates to a method for producing a multilayer data carrier comprising a first layer which is made of plastic and has an upper face on which an opaque layer partially covering said upper face, for example a metal layer, is arranged. The data carrier has a second layer made of plastic which is disposed on the first layer and is transparent at least in a sub-region of the metal layer. The metal layer is partially removed by a laser to such an extent that the metal layer has at least one break. The metal layer is preferably laminated between the first and the second plastic layers.

摘要： A security foil including at least a carrier layer, a protection layer and a functional layer. The functional layer has at least one clearance. The security foil includes a printed layer arranged within and partially filling the clearance and adjacent to and non-overlapping with the functional layer. The printed layer represents a marking. Also disclosed is a method for producing such a security foil from an original foil by selectively removing parts of the functional layer of the original foil to produce the clearance in the functional layer and by printing a marking within the clearance to produce the printed layer adjacent to and non-overlapping with the functional layer.

摘要： A multilayer laminate identification document including an outer layer having a contoured surface image formed therein via laser ablation. The contoured surface image has contours based on a digital monochrome image, and has a first appearance when viewed in reflected light at a first angle and a second, different appearance when viewed in reflected light at a second, different angle. The multilayer laminate identification document is formed by generating a second digital monochrome image with continuous pixel patterns from a first digital monochrome image, and irradiating the surface of the identification document with a laser using the second digital monochrome image as a guide to form a contoured surface image in the surface of the identification document.

摘要： A security element has a transparent film, a pattern of transparent and non-transparent regions on a first side of the transparent film, and a pattern of transparent and non-transparent regions on a second side of the transparent film. The pattern on the second side of the transparent film matches or is in register with the pattern on the first side of the transparent film. A color changing layer covers the pattern on at least one side of the first and second sides of the transparent film.
