Abstract: A device for producing a screen printing stencil has a light source for emitting a bundle of light whose focus lies in the region of a light-sensitive layer present on a stencil screen. Furthermore, there is an apparatus for generating a relative movement between the bundle of light being incident on the light-sensitive layer in accordance with a desired stencil pattern. The bundle of light is linearly polarized in at least one section. An electro-optical modulator for rotating the plane of oscillation of the bundle of light is arranged in this section. The electro-optical modulator rotates the plane of oscillation of the bundle of light in accordance with received stencil pattern data. An analyzer is positioned in the light path downstream of the electron optical modulator. The analyzer passes the bundle of light having a plane of oscillation at one orientation and blocks the bundle of light having a plane of oscillation at an opposite orientation.

Abstract: Method and apparatus for producing a grey-shade stencil in which a pattern which is bounded by edges is transferred, with a grey-shade grid superimposed on it, into a radiation-sensitive base. The grid is extended continuously over edges of the pattern which come to rest on one another, in order to avoid strips being formed in the area of mutually adjacent edges of pattern reproductions.
