Description
fende Linien werden dabei sauber ausgedruckt. Kratzspuren der Schreibelektrode oder Unregelmäßigkeiten sind nicht feststellbar.Any lines are printed out cleanly. Scratch marks on the writing electrode or irregularities are not detectable.
Die elektrisch beschreibbare Flachdruckplatte 20 kann neben den ausgebrannten Aufzeichnungen zur Korrektur oder Ergänzung mit einem Fettfarbstift oder mit einer Schreibmaschine mit Fettfarbband beschriftet werden. So werden z. B. Diagramme, deren Funktionskurven von der Ausbrennelektrode eines Registriergerätes aus der Metallschicht der Flachdruckplatte ausgebrannt wurden, mit einem Fettfarbstift beschriftet.The electrically writable planographic printing plate 20 can be used in addition to the burned-out records Correction or addition written with a bold pencil or with a typewriter with bold ribbon will. So z. B. Diagrams, the function curves of which from the burnout electrode of a The recorder was burned out of the metal layer of the planographic printing plate with a grease pencil labeled.
Ein bevorzugtes Anwendungsgebiet für die elektrisch beschreibbare Flachdruckplatte bietet die Vervielfältigung von Aufzeichnungen, die von einem Original über Kabel oder — bei großen Entfernungen — drahtlos über Funk übertragen werden. Danach können Informationsinhalte von Original-Aufzeichnungen mit einem Faksimileschreiber nach Patent 1 562 312 oder einem Klartextschreiber nach Patent 1 266 030 direkt und schnell auf die Flachdruckplatte übertragen werden. Ferner lassen sich mit diesen Geräten Flachdruckformen mit maßstäblich vergrößerten oder verkleinerten Abbildungen des Originals anfertigen.Duplication is a preferred field of application for the electrically writable planographic printing plate of recordings from an original via cable or - over long distances - be transmitted wirelessly via radio. After that, information content can be obtained from original records with a facsimile writer according to patent 1 562 312 or a plain text writer according to patent 1 266 030 can be transferred directly and quickly to the planographic printing plate. You can also use these Devices flat printing forms with scaled enlarged or reduced images of the original to make.
Ein seitenverkehrtes Abbild des Originals auf der elektrisch beschreibbaren Flachdruckplatte, wie es für den Lithosetdrack erforderlich ist, wird dadurch erzeugt, daß die Flachdruckplatte und das photoelektrisch abgetastete Original beim Übertragen der Aufzeichnung in zueinander entgegengesetzter Richtung bewegt werden.A reversed image of the original on the electrically writable planographic printing plate, like it for the lithosetdrack is required, is produced in that the planographic printing plate and the photoelectrically scanned original when transferring the recording in mutually opposite directions be moved.

The high-resistance 55, a monomolecular lubricating film 24 made of a mine cover layer, consists of a mixture of an electric oil which is vaporized.

Both the carbon layer and the lacquer layer 22 are exposed.

After the lubricating film 24 has been removed, the thickness is applied, which has the consequence that the metal surface of the planographic printing plate 20 with the known planographic printing plates wets prints with only water and now runs over an inking roller, delivering low resolution .
