Techniques for manufacturing a light field print using a printing press. The techniques include: identifying at least one characteristic of the printing press at least in part by printing at least one calibration pattern; obtaining content to be rendered using the light field print, the content comprising multiple scene views; generating, based at least in part on the content and the at least one characteristic of the printing press, a front target pattern and a back target pattern; and using the printing press to: print the front target pattern on a first side of a substrate; and print the back target pattern on a second side of the substrate.

A device for processing a document includes a processing device for providing a document to be processed with information when this is in an effective range of the processing device with information; and a traversing device with a document carrier device that can be traversed along a trajectory. The traversing device is configured to receive a document to be processed at a transfer position of the device on or at a document-carrying surface of the document carrier device; to move the received document into the effective range of the processing device for its processing and out of the effective range of the processing device after its processing. The document carrier device is traversed at least in sections, at least with respect to a direction of movement component along a specific (first) direction of movement, which runs orthogonally to a plane defined by three different points on the document-carrying surface.

A method for producing a multilayer body, as well as a multilayer body produced thereby. 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.
