Klischograph K 151 (1951)  

The Klischograph scans a picture line by line, and the resulting scan signal is used to control a steel stylus, which engraves more or less deep cuts into the surface of a printing plate, depending on the grey tone value of the pixel being scanned. The material of the printing plate can be either plastic or metal. This results in a screened printing plate for letterpress printing or for gravure printing.

  The material to be engraved is mounted on a table, which moves back and forth under the engraving stylus. The picture original is mounted on the bottom side of the same table, and is scanned from below. This makes the engraved picture on the printing plate automatically wrong-reading, as required for the printing process. The original picture must have the size in which it shall be printed.

Helio HGS

Using the same principle, the Helioklischograph was developed later, which engraves pictures and text with a diamond stylus into the copper surface of a printing cylinder for rotogravure printing. Such machines are still used today to produce rotogravure printing cylinders for high volume printing of magazines, catalogues, and packaging material.

The company HELL Gravure Systems GmbH & Co. KG in Kiel, which is a split off of the company Hell, still produces this kind of machines.
