Description

Verfahren zum Herstellen von Hochdruckformen. aus Kunstharz durch Prägen Die Erfindung bezieht sich auf ein Verfahren zum Herstellen von Hochdruckformen aus Kunstharz durch Prägen.Process for the production of letterpress forms. made of synthetic resin Embossing The invention relates to a method for producing relief printing forms made of synthetic resin by embossing.

Die kennzeichnenden Merkmale der Erfindung bestehen darin, daß eine mittels einer Hochdruckform geprägte, in einer heißen Flüssigkeit quellbare Kunstharzplatte oberflächlich abgeschliffen und dann in einer heißen Flüssigkeit so lange gequollen wird, bis die vorher vertieften Stellen erhaben sind.The characterizing features of the invention are that a Synthetic resin sheet, embossed in a high pressure mold and swellable in a hot liquid Abraded on the surface and then swollen in a hot liquid for so long until the previously recessed areas are raised.

Durch diese Maßnahme lassen sich auf einfache Art und Weise aus Kunstharz bestehende Hochdruckformen schaffen, ohne daß z. B. ein Gießverfahren öder ein Pantographierverfahren angewendet werden muß.This measure can be made of synthetic resin in a simple manner create existing letterpress forms without z. B. a casting process or a pantography process must be applied.

Gemäß der Erfindung wird eine Kunstharzplatte verwendet, die beispielsweise aus Phenol-, Harnstoff- oder Vinylharzen besteht, wobei die Zusammensetzung so ist, daß die Platte in einer heißen Flüssigkeit quellbar ist. In eine solche Platte wird gemäß des Verfahrens mittels Hochdruckformen die Schrift eingeprägt, und zwar nachdem die Platte vorher in einer heißen Flüssigkeit, z. B. in Wasser, entsprechend erweicht wurde. Hierauf wird diese Platte unter dem Prägedruck zum Erkalten gebracht. Nach Herausnahme der Kunstharzplatte aus der Prägepresse wird dieselbe oberflächlich abgeschliffen. Durch nochmaliges Erhitzen der geprägten und abgeschliffenen Platte in einer heißen Flüssigkeit quellen die Bildstellen, die vorher vertieft waren; über die Plattenoberfläche empor, während an den abgeschliffenen Stellen die geprägten Stellen nur bis zu der ursprünglichen Oberfläche quellen. Das Verfahren eignet sich in gleicher Weise wie für Hochdruckformen auch zur Herstellung von Schildern u. dgl.According to the invention, a synthetic resin plate is used, for example consists of phenolic, urea or vinyl resins, the composition being such that the plate is swellable in a hot liquid. In such a plate will be embossed according to the method by means of letterpress printing, namely after the plate beforehand in a hot liquid, e.g. B. in water, softened accordingly became. This plate is then brought to cool under the embossing pressure. To Removal of the synthetic resin plate from the embossing press becomes the same superficially sanded off. By heating the embossed and sanded plate again the image areas that were previously deepened swell in a hot liquid; above the surface of the plate, while the embossed areas on the ground off Swell places only up to the original surface. The procedure is suitable in the same way as for letterpress forms also for the production of signs and the like. like
