Klischograph K 155

By the Klischograph, the image is scanned line-by- line and with the electrical signal derived therefrom, a steel stylus is actuated which, depending on the gray value of an image point, engraves a more or less large depression into a plastic plate or a metal plate. This results in a rasterized letterpress or gravure print plate.

The material to be engraved is attached to the engraving drum (right), the image template is mounted on the scanning drum (left). During the engraving process, the scanning head and the engraving head move toward one another, so that the printing forme is automatically mirror-inverted engraved as required for printing. The scale is determined by the circumference of the scanning drum and the feed speed of the scanning head. The following fixed standards are available:
180%, 130%, 100%, 80%, 65%, 50%

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.
