Abstract
In an apparatus and a method for producing diffraction- and interference-active structures by micro-pattern stamping a metal object, a micro-stamping arrangement is provided including a micro-stamping station with a micro-pattern stamp for generating a diffraction-active structure on the metal object, an application station for applying a protective layer to the diffraction-active structure and a macro-stamping station for applying a macroscopic image relief over the diffraction active structure while it is protected by the protective layer.
