  • Method of applying a pattern to a surface of a substrate
    Patent number: 6083571
    Abstract: A method of applying a pattern to a surface of a substrate includes forming mutually parallel pattern rows applied by at least two output channels. In order to produce a pattern without strip-like visible faults, provision is made for the output channels in each case to be displaced transversely in relation to the pattern rows such that pattern rows can optionally be applied by at least some of the output channels in order to obtain a complete pattern. The individual pattern rows are applied by different output channels and are mixed with one another.

  • Device for producing a screen printing stencil
    Patent number: 5781224
    Abstract: In the production of a screen printing stencil, a thin-walled hollow cylinder having a light responsive layer on the outside is rotated about its cylinder axis and exposed by means of a laser beam impinging on it. The laser beam is focused in the region of the light responsive layer. The laser beam is moved in the direction of the cylinder axis, and is switched on and off in agreement with a desired stencil pattern. A radial deviation of the actual position of the wall of the hollow cylinder from its ideal position is determined from at least one measuring position fixed relative to the laser beam for a multiplicity of circumferential positions of the hollow cylinder. A first actuating signal is then derived from at least one of the radial positional deviations obtained at the measuring positions.
