Abstract: Examples include a security document having a substrate with a transparent window. In the region of the transparent window, a micro-optical structure including microlenses is arranged on one side of the substrate and a first print image is arranged on the other side of the substrate, opposite the micro-optical structure. A layer covers at least a section of the first print image. The layer allows electromagnetic radiation having a wavelength in the range of 380 nm to 780 nm to pass with a transparency in a range between 10% and 90%. The transparency gradually varies over a planar extension of the layer. A second print image is arranged on the layer in such a way that the second print image, or at least a piece of information contained therein, can be brought into alignment with the micro-optical structure after carrying out a folding process and becomes visible and/or recognizable.

Abstract: In some examples, photographic mapping of an object takes place during transport at a fixed position by means of a line camera in a sequence of recording periods. An exposure device is exposed for an exposure time that is dependent on the duration of the on-time of the line camera. Each strip-shaped portion of the object to be photographically mapped is exposed, within a recording period, asynchronously for the duration of a first exposure time to white light and for the duration of a second exposure time either to ultraviolet light or to IR light. Each strip-shaped portion of the print image to be photographically mapped is alternately exposed by the exposure device, within the recording period photographically mapping the portion, to white light and either to UV light or to IR light during the duration of the on-time of the line camera.

CPC classification number: B41F33/0036 , B41N3/003
Abstract: Some examples include checking the quality of printed products that are consecutively produced by multiple printing presses to have at least three printed patterns spaced apart from one another. The printed patterns are printed using different printing processes, such as a steel engraving process, an offset printing process, and a screen printing process that may be used for printing the three printed patterns of each printed product. A screen printing press is used for the screen printing process, with multiple steel plates being alternately used in the same production operation for the steel engraving process in an intaglio printing press. For at least two of the steel plates involved in carrying out the steel engraving process, a processing unit may selectively ascertain the deviation of the respective value of the relevant distances associated with the printed patterns, which may be instantaneously ascertained from a defined scale.
