Abstract
A method and a device for producing and transferring diffractive microstructures to a printing material include applying a fluid to an embossing cylinder and there, during the rotation of the embossing cylinder, solidifying the fluid to such an extent that the fluid is transferred to a printing material in the manner of a film with a solidified microstructure. The embossing cylinder has a cover which is preferably constructed to be either soft as a 'flexoshim' or hard as a 'nickel shim.' A web-fed or sheet-fed rotary printing press having the device is also provided.
