Description
Verfahren zur Herstellung von Gelatine-Tiefdruckformen. Die Erfindung betrifft ein Verfahren zur Herstellung von Gelatinetiefdruckformen, welche durch einseitiges Kopieren in einer Chromatgelatineschicht, die sich auf einem undurchsichtigen Träger in beliebiger Stärke befindet, erzeugt werden. Es sind bereits Verfahren bekannt zur Herstellung von Gelatine-Tiefdruckformen, bei welchen transparente Träger für die Chromatgelatineschicht verwendet werden, und bei denen entweder ein Kopieren von der Vorder- und der Rückseite der Gelatineschicht oder eine künstliche Rastererzeugung in dem transparenten Träger stattfindet und hinterher ein Kopieren von der Rückseite erfolgt. Dieses Kopierverfahren von der Vorder- und Rückseite wird gemäß der Erfindung vermieden.Process for the production of gelatine gravure forms. The invention relates to a process for the production of gelatin intaglio printing forms, which by one-sided copying in a chromate gelatin layer, which is on an opaque one Carriers of any strength are generated. There are already procedures known for the production of gelatine gravure forms, in which transparent carriers can be used for the chromate gelatin layer, and where either a copying from the front and back of the gelatin layer or an artificial grid generation takes place in the transparent carrier and afterwards a copying from the rear side he follows. This front and back copying method is carried out according to the invention avoided.
Das Verfahren wird in folgender Weise ausgeführt. Eine geeignete undurchsichtige Unterlage wird mit Chromatgelatinemasse übergossen. Nach dem Trocknen wird auf der Gelatineschicht zunächst das Diapositiv und dann darüber die Tiefdruckrasterplatte kopiert. Die vom Licht getroffenen Stellen der Chromatgelatineschicht sind entsprechend der verschiedenen Lichteinwirkung mehr oder weniger stark gehärtet, so @daß die Gelatinehaut beim nachfolgenden Behandeln mit heißem feuchten Dampf zusammenschrumpft und dabei der verschiedenen Härtung entsprechend Erhöhungen und Vertiefungen aufweist. Über das ganze Bild verteilt liegt in.gleichmäßiger Höhe der Tiefdruckraster, welcher bis auf den Grund der Gelatineschicht durchbelichtet wurde und daher keine Veränderung durch die Dampfbehandlung erfahren hat. Die so erhaltene Form kann nach Art einer Tiefdruckform zum Druck benutzt werden.The procedure is carried out in the following manner. A suitable opaque Chromat gelatin mass is poured over the base. After drying, the Gelatin layer first the slide and then the gravure grid plate over it copied. The areas of the chromate gelatin layer hit by the light are corresponding the various exposure to light more or less hardened, so @ that the Gelatin skin shrinks when subsequently treated with hot, moist steam and has elevations and depressions corresponding to the different hardening. The gravure screen, which is distributed over the entire image, is at an even height was exposed to the bottom of the gelatin layer and therefore no change experienced by the steam treatment. The shape obtained in this way can be in the manner of a Gravure form can be used for printing.
