Description

Verfahren zur Herstellung und Auffrischung von ausgedruckten metallenen Flachdruckplatten. Die Erfindung bezieht sich auf ein Verfahren zur Vorbereitung und Auffrischung von ausgedruckten metallenen Flachdruckplatten, nach welchem die Platte ohne besonderes Ablaugungs- und Präparationsbad zugleich mit dem Schleifprozeß abgelaugt und präpariert wird. Zu diesem Zwecke wird dem Schleifpulver in einem bestimmten Mischungsverhältnis Kali-Alaun zugefügt, durch das die Platte während des Schleifens druckfähig gemacht wird.Process for the production and refreshment of printed metal Planographic printing plates. The invention relates to a method of preparation and refreshing printed metal planographic printing plates after which the Plate without a special leaching and preparation bath at the same time as the grinding process is sucked off and prepared. For this purpose, the abrasive powder is used in one A certain mixing ratio of potash and alum is added, which makes the plate during of sanding is made printable.

Wenn die Platte fertiggeschliffen ist, wird sie aus der Maschine herausgenommen, auf dem Waschtisch gut abgespült und mit einer weichen Bürste durch Wasser abgebürstüt. Nachdem die Platte getrocknet ist, ist sie fertig zum Umdruck oder Lithographieren.When the plate is finished, it is removed from the machine, Rinsed well on the vanity and brushed through water with a soft brush. After the plate has dried, it is ready for transfer printing or lithography.

Solche Schleifsande mit Zusatz von insbesondere organischen Säuren sind für Lithographiesteine bekannt (schweizerische- Patentschrift 62181). Der Erfinder behauptet aber, daß sie sich für lithographische Metallplatten nicht eignen.Such abrasive sands with the addition of organic acids in particular are known for lithography stones (Swiss patent specification 62181). The inventor but claims that they are unsuitable for metal lithographic plates.
