A bending system for separating a page from a cover of a value document, wherein the page is connected to a spine of the cover, the spine separating the cover in first and second cover portions, wherein an angle γ is formed between the first and second cover portions. The bending system includes a bending unit connected to a motor, wherein the motor is configured to operate the bending unit such that the bending unit bends the value document to a first state, where γ is larger than 180°, and then back to a second state, where γ is at least 180° but less than γ in the first state, to separate the page from the cover. Also disclosed is an engraving system for engraving a front side and backside of a page of the value document and a document manufacturing device including the bending system and engraving system.

A visual security feature is provided that is disposed on a target. The visual security feature includes two substantially transparent layers. At least one of the two substantially transparent layers is present in an image-wise pattern.

An IR and/or UV machine-readable optical security device (e.g., micro-optic security thread) that is made up of at least one IR-absorbing component with a characteristic IR signature detectable at two or more IR-wavelengths, at least one UV-absorbing component with a characteristic UV signature detectable at two or more UV-wavelengths, at least one IR-absorbing component that absorbs IR light and emits light at a different invisible wavelength, at least one UV-absorbing component that absorbs UV light and emits light at a different invisible wavelength, or a combination thereof, is provided. The IR and UV machine-readable features do not interfere with the optical effects projected by the optical material.

A method for producing a multilayer body, with the steps of: a) providing a substrate film with a replication layer; b) molding a surface relief appearing to the observer in the form of a three-dimensional free-form surface, which is formed in particular by structures with a lens-like design generating a magnifying, demagnifying or distorting effect, into a surface of the replication layer; c) applying a first metal layer to the surface of the replication layer forming the surface relief; d) wet-chemically applying an at least partially transparent spacer layer to the metal layer; e) applying a second metal layer to the spacer layer.
