   Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von Druckformen für Strichzeichnungen, Autotypien und andere nach Art von Strichzeichnungen in Linien oder Punkte zerlegte Halbtonbilder. bei dem die Herstollung durch direkte Belichtung in   der   photographischen Kamera erfolgt, derart, dass das Objekt, z. B. eine Zeichnung, ein Plan und dgl., direkt mittels Objektiv und Kamera auf der   Druckplatte, die   mit einer lichtempfindlichenSchichtvonderuntenangegebenenZusammensetzungüberzogenist,   aufgenommen wird. Die Platte   wird nach der Belichtung in bekannter Weise entwickelt und dient dann selbst als   Druckform.

 EMI1.1
 bring plate.



   The present invention relates to a method for producing printing forms for line drawings, autotypes and other halftone images broken down into lines or dots in the manner of line drawings. in which the manufacture takes place by direct exposure in the photographic camera, such that the object, e.g. A drawing, a plan and the like is recorded directly by means of a lens and camera on the printing plate, which is coated with a photosensitive layer of the composition given below. After exposure, the plate is developed in a known manner and then itself serves as a printing form.
