Description

Verfahren, photographische Gelatinebilder zum Druck mit Fettfarben geeignet zu machen. Die Erfindung besteht darin, photographische Positive so heranzurichten, daB ein Fettfarbenäuftrag auf die trockene Bild-~fläche zrr@gli@t; - ohne dieüdwkng zu` vermischen, so dafi man mit dem eingefärbten Positiv drucken kann. Der Zweck ist der, bei Herstellung kleiner Auflagen von Reproduktionen die kostspielige Herstellung von Druckplatten zu umgehen, zugleich aber dem Kunstgewerbler ein Mittel in die Hand zu geben, die Tönung der Farbe seinem, künstlerischen Empfinden nach selbst zu wählen Das Verfahren ist folgendes. Ein auf gewöhnlichem: Wege hergestelltes trockenes Gel'atinelichtbild wird in ein Bad aus verdünntem Ammoniak gebracht, das die: Aufquellung der Gelatineschicht bewirkt. Nach erfolgter Abspülung mit Wasser wird das Bild in eine wässerige verdünnte Ätzkalilösung gebracht. Der Zweck ist, die Zerteilung der Gelatine analog der Tönung zu bewirken. Es bildet sich dabei eine Körnung. Nach Wiederabspülung mit Wasser wird das Bild in ein drittes: Bad aus Wasser und Chlorkälziü3n-gefirac t;dieses@Bäd soll die durchdas Ätzkali erhaltene Körnung konservieren. Nach nochmaliger Spülung mit Wasser wird das Bild getrocknet und ist nun ;geeignet, Fettfarbe anzunehmen, und zwar mittels Einreibung, und sie auf Papier o. dgl. zu übertragen. Ist das Gelatinel:>ild -auf Glas, so kann es vermöge seiner Körnung als Negativ für Hochdruck oder als Diapositiv für Tiefdruck angewendet werden.Process, gelatin photographic images for printing with fat inks to make suitable. The invention consists in arranging photographic positives in such a way that that a grease paint application on the dry picture surface zrr @ gli @ t; - without dieüdwkng to mix so that one can print with the colored positive. The purpose is that, when producing small editions of reproductions, the costly production bypassing printing plates, but at the same time providing the craftsperson with a means of doing that To give hand, the tint of the color according to his, artistic feeling to choose The procedure is as follows. One made in the usual way dry gelatin photographic image is placed in a bath of dilute ammonia, which which: causes the gelatin layer to swell. After rinsing with water the image is placed in an aqueous dilute caustic potash solution. The purpose is to effect the division of the gelatin analogously to the tint. It forms in the process one grit. After rinsing again with water, the picture is transferred to a third: bath from water and chlorinated lime-fired; this bath is said to be the one obtained by the caustic potash Preserve the grain. After rinsing again with water, the picture is dried and is now; fit to take on the color of fat, by means of rubbing, and they to be transferred to paper or the like. If the gelatin:> ild - on glass, it can do Its grain size is used as a negative for letterpress printing or as a slide for gravure printing will.
