Patent ID: 7401550

Claim:
Apparatus for producing a marking on a substrate, wherein the marking produces a particular optical effect by having a diffractively or holographically acting surface structuring or a matt surface structuring which scatters incident light diffusely or directedly, comprising: a replication apparatus having a replication surface which is structured with a surface relief, wherein the surface relief is in the form of a negative for the surface structuring of the marking; a device for producing radiation, preferably a laser installation, which co-operates with the replication apparatus, by the radiation being directed onto at least one irradiation region of the replication apparatus for producing regions of different temperatures on the replication surface forming at least one shaping region defining the marking; and a counterpressure apparatus, wherein the substrate is arrangeable between the replication apparatus and the counterpressure apparatus in order to shape the shaping region onto the substrate in a contact region where the replication surface contacts the substrate, producing the surface structuring, and wherein the feed of the radiation for producing the shaping regions extends outside the substrate, and wherein a position of an impingement point of the radiation on the replication surface is controllable by a one-dimensional or multi-dimensional movement of the radiation and or that the power density in relation to surface area of the radiation at the impingement point of the radiation on the replication surface is controllable, and wherein a control sequence for actuation of the radiation-producing device is extendable over more than one operating cycle of the replication apparatus and wherein a chance in the selection of the shaped region is effectable by a change in the temperature distribution on the replication surface.
