Embossing device for embossing micro- or nanostructures

The invention relates to a device for producing security elements, wherein the security elements are arranged on a front side and a rear side of a film web, and are formed by embossed structures in acoating layer with dimensions in the region of micro- or nanometers. According to the invention, in the conveying direction of the film web, the device has the following equipment: a device for providing a film web; a first printing mechanism for applying a first coating layer that can be cured via ultraviolet light to the rear side of the film web; a first embossing mechanism for embossing firststructures with dimensions in the region of micro- or nanometers in the first coating layer; a second printing mechanism for applying a second coating layer that can be cured via ultraviolet light tothe front side of the film web; and a second embossing mechanism for embossing second structures with dimensions in the region of micro- or nanometers in the second coating layer. According to the invention, the film web travel
