Description

Herstellung von Acetylcellulosereliefmatern. Klischees aus Acetylcellulose durch heißes. Abprägen herzustellen, ist bekannt und bietet keine Schwierigkeiten. Sie haben ebene Druckfläche. Im Gegensatz hierzu stehen Reliefmatrizen, welche erhebliche Höhen- und Tiefenunterschiede aufweisen. Man verwendet diese ausschließlich im Zeitungsbilddruck. Es, sind demnach immer nur Autotypiereliefs. Ein solches Original zu vervielfältigen unter Anwendung von Celluloidpositiven nach Patentschrift 116252 ist erfolglos. Um die nötige Schärfe der tieferliegenden Stellen zu erhalten, ist man gezwungen, das leichter schmelzende Celluloid sehr zu erwärmen, fast bis- zum Schmelzpunkt, was aber gefährlich ist. Ferner läßt das Celluloidpositiv nur sehr wenige Vervielfältigungen zu, da das Relief schwindet. Im Gegensatz hierzu wird im vorliegenden Verfahren von dem Originalrelief ein Positiv auf galvanischem Wege hergestellt und zum Prägen verwendet. Ein solches Galvano bleibt gegen Hitze und Druck konstant, und es können nach ihm beliebige Anzahl Matern in bekanntermaßen nicht explosiver Acetylcellulose hergestellt werden. - Solche Matern sind gut verschickbar, was sehr ins Gewicht fällt, da die Mater hauptsächlich für die Provinzpresse fabriziert wird. Das Cellon muß fast bis zum Schmelzpunkt erwärmt werden und wird dann auf das positive Galvano mittels einer Presse gedrückt.Manufacture of acetyl cellulose relief materials. Acetyl cellulose clichés by hot. Producing an impression is known and does not present any difficulties. You have a flat printing surface. In contrast, there are relief matrices, which are considerable Have height and depth differences. These are used exclusively in newspaper printing. They are therefore always just car type reliefs. To reproduce such an original using celluloid positives according to patent specification 116252 is unsuccessful. In order to get the necessary sharpness of the deeper lying areas, one is forced to to warm the more easily melting celluloid, almost to the melting point, but what is dangerous. Furthermore, the celluloid positive allows very few replicas too, as the relief disappears. In contrast, in the present proceedings A positive made of the original relief by electroplating and for embossing used. Such a galvano remains constant against heat and pressure, and it can according to him, any number of materials in acetyl cellulose, which is known to be non-explosive getting produced. - Such matrices are easy to send, which is very important falls because the mater is mainly made for the provincial press. The cellon has to be heated almost to the melting point and is then on the positive electroplating pressed by means of a press.
