Umdruckplatte für Photolithographie.
Den Gegenstand der vorliegenden Erfindung bildet eine Umdruckplatte, zu deren Herstellung die lichtempfindliche Schicht in an sich bekannter Weise auf einer biegsamen Metallplatte befestigt wird, auf welche jedoch vorher eine Kautschuklage geklebt worden war. Man hat wohl schon die lichtempfindliche Schicht auf eine Metallplatte oder ein Blatt Papier gebracht und von diesen das Bild nach Entwicklung des Reliefs auf den Stein übertragen, wie andererseits auch Umdruckplatten bekannt sind, bei denen die lichtempfindliche Schicht auf einer Kautschukunterlage allein befestigt ist. Bei der Übertragung des entwickelten Bildes von einer Metallplatte oder einem Blatt Papier auf den Stein werden aber die hohen Stellen des Bildes zumeist breit gedrückt und das Bild erhält ein zerrissenes, unscharfes Aussehen,
während die tiefen Stellen des Bildes gar nicht heraus-
EMI1.1
ist die lichtompfindliche Schicht auf eine nachgiebige Unterlage gebracht, die wohl in der Druckrichtung, d. h. vertikal zur Fläche des Bildes in gewissen Grenzen auszuweichen vermag, die aber andererseits dadurch, dass die als elastische Unterlage dienende Kautschukschicht mit einer Metallplatte fest verbunden ist, Verzerrung durch Dehnen der Schicht ausschliesst.
Herstellung und Verwendung der neuen Umdruckplatte vollziehen sich in folgender Weise : Auf ein Zinkblech oder eine andere feste Unterlage wird eine dünne Schicht aus homogenem Material, z. B. Kautschuk, mit Kautschuk imprägniertes oder anderes dichtes Gewebe, Leder, Wachstaffct, Karton usw. aufgeklebt. Die so erhaltene Platte wird, um die Gelatine der Iicl1tempfindlichen Schicht an der Unterlage haften zu lassen, mit Wasserglas überzogen, bei etwa 250 getrocknet und darauf mit einer Auflösung von Gelatine und Kaliumbichromat oder ähnlich wirkenden Stoffen, wie sie beim Lichtdruck verwendet werden, bedeckt. Nach einigen Stunden des Trocknens ist die Platte zum Anfertigen einer Matrize fertig.
In bekannter Weise wird dann'hieraus unter Benutzung eines Negativs die Licht- druclunatrize hergestellt. Diese wird weiter mit Umdruckfarbe eingerollt und auf einem lithographischen Stein unter dem Reiber einer Presse durchgezogen. Dadurch wird auf dem

Transfer plate for photolithography.
The subject of the present invention is a transfer printing plate, for the production of which the photosensitive layer is fastened in a manner known per se to a flexible metal plate, to which, however, a rubber layer had previously been glued. The light-sensitive layer has probably already been applied to a metal plate or a sheet of paper and from this the image has been transferred to the stone after the relief has developed, as are also known transfer printing plates in which the light-sensitive layer is attached to a rubber base alone. When transferring the developed image from a metal plate or a sheet of paper to the stone, however, the high areas of the image are usually pressed wide and the image takes on a torn, blurred appearance,
while the deep parts of the picture cannot be
EMI1.1
the light sensitive layer is placed on a flexible base, which is probably in the printing direction, i.e. H. vertically to the surface of the picture is able to deviate within certain limits, which on the other hand, because the rubber layer serving as an elastic base is firmly connected to a metal plate, excludes distortion due to stretching of the layer.
The production and use of the new transfer printing plate take place in the following way: A thin layer of homogeneous material, e.g. B. rubber, impregnated with rubber or other dense fabric, leather, wax fabric, cardboard, etc. glued on. The plate obtained in this way is coated with water glass in order to allow the gelatine of the sensitive layer to adhere to the base, dried at about 250 ° C and then covered with a solution of gelatine and potassium dichromate or similar substances as used in photographic printing. After a few hours of drying, the plate is ready for making a matrix.
The light pressure matrix is then produced in a known manner using a negative. This is then rolled up with transfer ink and drawn through on a lithographic stone under the grater of a press. This will result in the

Lichen lithographic process can print any number of images.
