Description

Verfahren zur Herstellung von Gelatinedruckformen. Zusatz zum Patent 413142. Die Erfindung betrifft eine Ausbildung des Verfahrens zur Herstellung von Gelatinedruckformen nach Patent 413I42.Process for the production of gelatin printing plates. Addition to the patent 413142. The invention relates to an embodiment of the method for producing Gelatin printing plates according to patent 413I42.

An Stelle der irn Patentanspruche vorgesehenen Quellung der Gelatine nach der Belichtung und vor der Behandlung mit feuchtem Wasserdampf kann auch zur Erzielung eines tieferen Punktes zuvor eine Halbauslösung der unbelichteten Teile der Gelatineschicht in lauwarmem Wasser durch Eintauchen in lauwarmes Wasser oder durch mechanische Überreibung der Gelatineschicht mit einem in lauwarmes Wasser getauchten Bausch aus Watte oder ähnlichem Stoffe erfolgen. Ferner kann vor der Behandlung mit feuchtem Wasserdampfe die Abdeckung einzelner Teile der Gelatineschicht durch Asphaltlack oder eine ähnliche, die Schicht vor der Einwirkung des Dampfes schützende Substanz erfolgen. Diese Verfahren tragen erheblich zur Erzielung einer guten Bildwirkung bei, da durch dieselben die Punkte tiefer gelegt und Partien des Bildes, die einer weiteren Behandlung bedürfen, vor einer Einwirkung des Dampfes auf die freigelegten Punkte geschützt werden.Instead of the swelling of the gelatin provided for in the patent claims after exposure and before treatment with moist steam can also be used for To achieve a lower point, half-release the unexposed parts beforehand the gelatin layer in lukewarm water by immersion in lukewarm water or by mechanically rubbing the gelatin layer with lukewarm water dipped pad made of cotton wool or similar materials. Furthermore, before the Treatment with moist steam to cover individual parts of the gelatin layer by asphalt paint or similar, the layer before the action of the steam protective substance. These procedures contribute significantly to the achievement of a good pictorial effect, since the same places the points lower and parts of the Images that require further treatment before exposure to steam on the exposed points are protected.
