Abstract
Das Verfahren zur Herstellung von für den Offsetdruck geeigneten Drucktüchern, die durch Auftragen einer Schicht aus einem porösen, elastischen Material auf eine aus Faser material bestehende Trägerschicht erhalten werden, beruht auf der Erkenntnis, daß bei Aufbringen einer Schicht eines treibmittelhaltigen Polyvinylchloridplastisols, das in der Wärme expandiert und ausgeliert wird, auf die Trägerschicht, ein Drucktuch entsteht, das insbesondere bei den ersten Abzügen unscharfe Druckbilder ergibt. Dieser Nachteil wird durch einen dünnen Aufstrich behoben, der auf die freie Ober fläche der porösen Schicht aufgebracht, die nachteilige Wir kung des in der porösen Schicht enthaltenen Weichmachers auf die Wiedergabe des Druckbildes verhindert. The process of making for offset printing suitable printing blankets by applying a layer from a porous, elastic material to a fiber material existing carrier layer are obtained based on the knowledge that when a layer is applied a blowing agent-containing polyvinyl chloride plastisol, which in the Heat is expanded and emitted onto the carrier layer, a printing blanket is created, especially with the first Prints of fuzzy prints result. This disadvantage will fixed by a thin spread on the free upper surface of the porous layer applied, the disadvantageous We the plasticizer contained in the porous layer prevents reproduction of the printed image.
