Description

Verfahren zur Herstellung von Druckstöcken aus einer photographischen Platte bzw. einem photographischen Film Man hat bereits Gelatinesilberbilder mit Wasserstoffsuperoxyd in Mischung mit Bromkalium, Kupfersulfat und Salpetersäure behandelt, um Reliefs für photomechanische Zwecke :oder für den. Pressendruck zu erhalten.Process for the production of printing blocks from a photographic Plate or photographic film You already have gelatin silver pictures Hydrogen peroxide mixed with potassium bromide, copper sulphate and nitric acid treated to reliefs for photomechanical purposes: or for the. Press pressure too obtain.

Die Erfindung geht darauf aus, ebenfalls solche Druckstöcke aus Gelatines.ilberbildern auf photographischen Platten bzw. Filmen herzustellen, die besonders dauerhaft und widerstandsfähig sind.The invention is based on such printing blocks from gelatines.ilberbildern on photographic plates or films that are particularly durable and are resistant.

Zu 'diesem Zwecke wird das in üblicher Weise entwickelte Silberbild in einer Lösung von Brom-Kaliüm-Kupfersulfat und verdünnter Salzsäure behandelt, danach in ein Bad aus warmem Wasser eingebracht und schließlich in einem Härtungsbade, gebildet aus einer Eisenchlorid- oder Chrom-Alaun-Lösung, behandelt. Die Behandlung in den beiden Bädern wird mehrfach wiederholt, in der Weise, daß dabei die Platte bzw. der Film im ersten Bade zunächst nur kurze Zeit und in den nachfolgenden Behandlungen in anwachsenden Zeiträumen verbleibt, wonach schließlich zwecks schneller Trocknung anschließend -noch ein Acetonbad Anwendung finden kann.The silver picture developed in the usual way is used for this purpose treated in a solution of bromine-potassium-copper sulfate and dilute hydrochloric acid, then placed in a bath of warm water and finally in a hardening bath, formed from a ferric chloride or chromium alum solution, treated. The treatment in the two baths is repeated several times, in such a way that the plate or the film in the first bath only for a short time and in the subsequent treatments remains in increasing periods, after which finally for the purpose of faster drying then an acetone bath can still be used.

Auf diese Weise werden die für den Druck in Betracht kommenden Teile der Platte bzw. des Films derart herausgehoben, daß ein kräftiger Höhenunterschied entsteht und vollkommen gehärtet. Das Acetonbad kann natürlich nur in den Fällen, wo, es angängig ist, z. B. bei Verwendung von Glasplattennegativen, Anwendung finden.In this way, the parts to be considered for printing become the plate or the film lifted out in such a way that a significant difference in height arises and completely hardened. The acetone bath can of course only be used in cases where, it is accessible, e.g. B. when using glass plate negatives, application.

Die einzelnen Teile des Verfahrens sind an sich bekannt, und nur durch das Gesamtverfahren wird der beabsichtigte Zweck erreicht.The individual parts of the process are known per se, and only by the overall process achieves the intended purpose.
