Abstract (en)
[origin: WO2017041896A2] The invention relates to a sheet-fed press (40) for printing and embossing printed sheets (50) for producing security elements (14) with an optically variable structure (20), comprising at least one printing unit (44-1, 44-2), which is designed and equipped to coat (22) the printed sheets (50) with a repeating pattern (22-1, 22-2), an embossing unit (46) which is designed and equipped to provide the printed sheets (50) with a fine-structured embossing structure (26), and comprising conveying systems for guiding the printed sheets (50) within the sheet-fed press (40) on a peripheral gripping structure, the printed sheets being gripped through the at least one printing unit (44-1, 44-2) and the embossing unit (46) in order to produce the finely structured embossing structure (26) and to apply the coating (22) in an adapted manner to the printed sheets (50) and to thus form the optically variable structure (20) of the security element (14) which is to be produced. The invention also relates to a method for producing a security element with an optically variable structure (20) in said type of sheet-fed press, a flexible embossing plate (70) for said type of sheet-fed press and to a method for producing said type of embossing plate.
