A single- or multi-layered first decorative ply is applied to a carrier ply with a first and a second side. A metal layer is applied to the side of the first decorative ply facing away from the carrier ply and structured such that the metal layer is provided with a first layer thickness in one or more first zones and is provided with a second layer thickness different from the first layer thickness in one or more second zones, wherein in particular the second layer thickness is equal to zero. A single- or multi-layered second decorative ply is applied to the side of the metal layer facing away from the first decorative ply and structured using the metal layer as mask such that the first or second decorative ply is at least partially removed in the first or second zones.

摘要： A method of manufacturing a security device including: conveying a substrate web including a photosensitive film along a transport path; exposing the photosensitive film to radiation of a predetermined wavelength through a mask, wherein the mask includes a predetermined pattern of regions which are substantially opaque to radiation of the predetermined wavelength and at least semi-transparent to radiation of the predetermined wavelength, respectively; during the exposure, moving the mask alongside the substrate web along at least a portion of the transport path at substantially the same speed as the substrate web, such that there is substantially no relative movement between the mask and the substrate web; and heating the substrate web including the exposed photosensitive film. In this way, regions of the photosensitive film exposed to the radiation of the predetermined wavelength undergo an increase in optical density such that the photosensitive film displays a reproduction of the predetermined pattern.

摘要： The invention concerns a process for producing a film element having mutually registered metallic layers (11, 16) and a film element which can be produced by such a process. A first metallic layer (11) provided on a first surface of a flexible single-layer or multi-layer carrier film (10) and a masking layer (13) provided on the second surface of the carrier film (10), opposite to the first surface, are structured in accurate register relationship with each other by means of mutually synchronised structuring procedures. After structuring of the first metallic layer (11) and the masking layer (13) one or more further layers are applied to the first metallic layer (11). Applied to the one or more further layers (15) is a second metallic layer (16) to which a first photoactivatable layer (17) is applied. The first photoactivatable layer (17) is structured by means of trans-exposure through the masking layer (13), the first metallic layer, the one or more further layers and the second metallic layer (16) from the side of the masking layer (13) by means of electromagnetic radiation of a wavelength to which the first photoactivatable layer (17) is sensitive, or the first photoactivatable layer is exposed controlledly through the masking layer from the side of the film body that is opposite to the masking layer.

摘要： The present invention describes methods and apparatuses for creating superposition shape images by superposed base and revealing layers of lenslet gratings. The superposition shape images form a message recognizable by a human observer or by an image acquisition and computing device such as a smartphone. The superposition shape images may be created by different superposition techniques ranging from 1D moiré, 2D moiré and level-line moiré superposition techniques to lenticular image and phase shift superposition techniques. Moiré superposition techniques enable creating superposition shape images at different apparent depth levels. Applications comprise the protection of documents and valuable articles against counterfeits, the creation of eye-catching advertisements as well as the decoration of buildings and exhibitions.
