Description

Verfahren zur Herstellung von Gelatinedruckplatten. Die Erfindung betrifft ein Verfahren zur Herstellung von Druckplatten, bei welchem eine lichtempfindliche Gelatineplatte zur Verwendung kommt. Es ist bereits vorgeschlagen, zur Erzeugung von Druckplatten bei Verwendung einer Chromatgelatineplatte die Platte nach der Belichtung in kaltem Was-@er zu entwickeln und alsdann der Einwirkung von trockener Hitze auszusetzen. Es ist ferner bekannt, bei Verwendung von Silbergelatineplatten nach der Belichtung und Entwicklung mit Pyrogallol die Platten mit Formalin zu härten und dann unter Anwendung höherer Temperatur schnell zu trocknen.Process for the production of gelatin printing plates. The invention relates to a method for the production of printing plates, in which a photosensitive Gelatin plate is used. It is already proposed for generation of printing plates when using a chromate gelatin plate, the plate after the To develop exposure in cold water and then to the action of drier Expose to heat. It is also known to use gelatin silver plates harden the plates with formalin after exposure and development with pyrogallol and then to dry quickly using a higher temperature.

Demgegenüber kennzeichnet sich das Verfahren der Erfindung dadurch, daß die Gelatineplatte nach der Belichtung mit feuchten Wasserdämpfen behandelt wird, und zwar kann die Behandlung mit Wasserdampf, wenn ('hromatgelatine verwendet wird, unmittelbar nach der Belichtung stattfinden, wobei sofort eine druckfähige Platte .erhalten wird. Bei Verwendung von Silbergelatine o. dgl. muß nach der Belichtung und Entwicklung zunächst eine Härtung stattfinden, bevor die Behandlung mit Wasserdampf erfolgen kann. Diese Behandlung geschieht am besten in der Weise, daß die vorbereitete Gelaäneplatte Wasserdämpfen ausgesetzt wird mit einer Temperatur, welche sich nach der Schmelzbarkeit der unbelichteten Gelatine richtet. Dieses Verfahren hat vor den bisherigen Verfahren den Vorzug, daß es erheblich einfacher ist und weniger Zeit beansprucht und dabei sofort druckfähige, trockene Platten liefert.In contrast, the method of the invention is characterized in that that the gelatin plate is treated with moist water vapors after exposure treatment with steam, if ('chromate gelatine is used will take place immediately after exposure, immediately being a printable Plate .is obtained. When using silver gelatin or the like. After exposure and development, curing first takes place before treatment with steam can be done. This treatment is best done in such a way that the prepared one Gelaäneplatte is exposed to water vapors with a temperature which varies according to the meltability of the unexposed gelatine. This procedure has before the previous methods have the advantage that it is considerably simpler and less Takes up time and delivers printable, dry plates immediately.
