A label, and methods and systems for preparing the label. The label includes a lens or lens array. The label includes at least one surface, a portion of which is embossed, and a lens array provided by the embossed portion of the at least one surface. The method includes applying a material to a substrate and contacting a surface of the material with a master engraving to provide an embossed region on a least a portion of the surface of the material, wherein the embossed region provides at least one lens.

The flat foil printing press comprises an evacuable back-pressure plate (9), with suction regions (15k) which run in the sheet running direction (X) and which are next to embossing regions (16k), in which foil webs (6k) run. The suction regions are subdivided into several suction segments (10i) which are successive in the sheet running direction, and are each connected to a vacuum source (14) by way of a vacuum feed line (12i) via a vacuum switching element (13i). With the running-out of an embossed sheet (5), firstly all suction segments (10i) covered by the sheet are evacuated, and subsequently the suction segments which are no longer covered by the sheet are successively disconnected from the vacuum source. This results in an error-free separation of foil webs and sheets, for a greater picture quality and machine output.
