Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Es ist bekannt, daß man dünne, für Druckzwecke bestimmte Bleche und Metallplatten zwecks direkten Kopierens und photochemischer Weiterbehandlung mit lichtempfindlichen und anderen Lösungen überziehen kann.It is known to use thin sheets and metal plates intended for printing purposes for the purpose of direct copying and photochemical further treatment with light-sensitive and other solutions.

Dieses Überziehen geschieht durch Übergießen und Egalisieren der Schicht mittels eines Schleuderapparates. This coating is done by pouring over and leveling the layer using a spinner.

Auf dünne Bleche in großen Formaten, wie solche für den algraphischen und Blechdruck in lithographischen Flach- oder Rotationspressen verwandt werden, läßt sich das vorstehend angegebene Verfahren jedoch nicht anwenden, eine photochemische Behandlung ist daher bis jetzt ausgeschlossen, weil es damit nicht möglich ist, eine für die Weiterbehandlung geeignete, ganz gleichmäßige Schicht zu erzielen.On thin sheets in large formats, such as those for graphic and metal printing are used in lithographic flat or rotary presses, the above can be However, do not apply the specified procedure, a photochemical treatment is therefore ruled out until now because it is so is not possible, a completely even layer suitable for further treatment to achieve.

Die Zeichnung muß daher entweder vonThe drawing must therefore either be from

Die erste Manier ist zeitraubend, und bei der zweiten muß erst ein Umdruck hergestellt werden, und die Zeichnung verliert beim Umdruck noch bedeutend an Schärfe.ao hand or by transfer or overprinting on such printing plates. The first one is time consuming, and the second one has to be reprinted first and the drawing loses its sharpness significantly when it is reprinted.

Die im Patent 295237 geschützte Erfindung ermöglicht es auch, Bleche, die für Druck-, zwecke bestimmt sind, in allen, selbst den größten Formaten mit lichtempfindlichen und anderen Lösungen durch Zerstäuben so tadellos zu überziehen, daß auch hier eine photochemische Weiterbehandlung stattfinden kann.The invention, which is protected by patent 295237, also makes it possible to manufacture sheets that are used for pressure, purposes are intended in all, even the largest formats with photosensitive and to coat other solutions so perfectly by atomization that here, too, a photochemical Further treatment can take place.

Um Bleche größeren Formates mit lichtempfindlichen und anderen Lösungen in entweder zusammenhängender oder durchbrechener, ganz gleichmäßiger Schicht zu überziehen, wird das zu überziehende Blech in bekannter Weise über einen walzenförmigen Holz- oder " Metallkern gespannt und befestigt. Das Blech bildet so den Überzug oder die Umhüllung der Walze und wird nun weiter genau so be-, handelt, wie solches im Patent 295237 für Druckwalzen angegeben ist.To large format sheets with photosensitive and other solutions in either to cover a coherent or broken, completely even layer, is the sheet to be coated in a known manner over a cylindrical wooden or " Metal core stretched and fastened. The sheet metal thus forms the coating or the casing of the roller and will now continue to be treated in exactly the same way as in patent 295237 for Print rollers is specified.

Nach dem Überziehen mit einer lichtempfindlichen Schicht kann das Blech entweder auf dem Walzenkern wie eine Druckwalze, oder vom Kern abgenommen und flach weiter behandelt werden.After coating with a photosensitive layer, the sheet can either be on the roller core like a pressure roller, or removed from the core and further treated flat will.
