A method for producing a film intermediate product (), a film intermediate product (), as well as a product produced hereby. The film intermediate product () is here formed by means of depositing one or more film elements (to), which is or are formed in each case of a cutout of one or more donor films (to).

Method for producing a film intermediate product, film intermediate product and method for producing a product

A method for producing a hologram (), () for security elements () and/or security documents (). One or more virtual hologram planes () are arranged in front of and/or behind one or more virtual models () and/or one or more virtual hologram planes () are arranged such that they intersect one or more virtual models (). One or more virtual light sources () are arranged on one or more partial regions of the surface () of one or more of the virtual models (). One or more virtual electromagnetic fields () are calculated starting from at least one of the virtual light sources () in one or more zones () of the one or more virtual hologram planes (). In the one or more zones (), in each case, a virtual total electromagnetic field () is calculated on the basis of the sum of two or more, of the virtual electromagnetic fields () in the respective zone (). One or more phase images () are calculated from the virtual total electromagnetic fields () in the one or more zones (). A height profile () of the hologram () is calculated from the one or more phase images () and the height profile () of the hologram () is incorporated into a substrate () to provide the hologram ().

Method for producing a hologram, and security element and a security document

A security element with one or more first microstructures, wherein the first microstructures are provided in each case in one or more tracks which are curved at least in sections or in one or more sections of a track which are curved at least in sections, and/or in each case run along one or more tracks which are curved at least in sections or along one or more sections of a track which are curved at least in sections, and a method, wherein at least one file containing image points of one or more image elements is provided, which includes the locational arrangement of the image points, and one or more tracks which are curved at least in sections or one or more sections of one or more tracks which are curved at least in sections are determined from the locational arrangement of the image points, and in the one or more tracks or sections of tracks in each case one or more first microstructures are provided which, when illuminated, provide a first item of optically variable information.
