Patent number: 6110652Abstract: In a method of three-dimensionally patterning the surface of a printing or embossing cylinder the surface of the cylinder is irradiated with exposure beams in accordance with the desired pattern and then the surface is patterned in accordance with the exposure. To achieve particularly fine structuring of the cylinder surface, the radiation dots serving to expose the surface are produced by means of beams which, before impinging on the surface of the cylinder, to form fine structures, are modified in accordance with the desired pattern by means of a beam-forming element. The pattern of the respective radiation dot which is impinged on to the cylinder surface is moved synchronously with respect to the movement of the cylinder surface in accordance with the rotary movement thereof.Type: GrantFiled: December 11, 1998Date of Patent: August 29, 2000Assignee: Leonhard Kurz GmbH & Co.Inventors: Wilhelm Stork, Heinrich Wild
