Description

Verfahren zur Herstellung von Drei- oder mehrfarbentiefdruckbildern unter Verwendung von farbenrichtig korrigierten Filmlichtdruckplatten Die bisher übliche Art der Herstellung von Drei- und Mehrfarbentiefdruckbildern erfolgt in der Weise, daß nach dem bunten Original zunächst Farbenauszüge im Halbton auf Trokkenplatten gemacht werden. Die dadurch zustande kommenden Teilnegative werden hierauf den Farbwerten des Originals entsprechend korrigiert und danach Diapositive angefertigt. Nachdem diese Diapositive retuschiert worden sind, werden Kopien auf Pigmentpapier gemacht und auf die Kupferwalze übertragen. Nach erfolgter Ätzung der Kupferwalze machen sich umständliche und schwierige Arbeitsvorgänge erforderlich, die in der Anfertigung der Probedrucke und der überarbeitung des Kupferzylinders bestehen. In dem meisten Fällen entsprechen die Andrucke bei weitem nicht dem Original. Die Abweichung in: dien Farben ist so erheblich, daß sie durch eine Überarbeitung der Kup-P;erzylind'er, die nur in sehr bescheidenen Grenzen erfolgen kann, nicht zu beheben ist. In, solchen Fällen müssen. neue Walzen geätzt werden, nachdem zuvor die Negative korrigiert und neue Diapositive angefertigt worden sind. Auch die zweiten Atzungen ergeben dann häufig noch nicht das richtige Bild, so daß die Arbeitsgänge zu wiederholen sind. Das neue Verfahren zur Herstellung von Drei- oder Mehrfarbentiefdruckbildern umgeht diese Schwierigkeiten dadurch, daß Diapositive hergestellt werden, nach deren Kopie zwangläufig farbenwertrichtige Tiefdruckätzungen entstehen. Man stellt in bekannter Weise Farbenauszüge in Halbtonmanier her, die mach der Retusche je .auf .eine Fihnlichtdruckplatte kopiert und in ebenfalls bekannter Weise für die Handpresse druckfertig gemacht werden. Wenn, evtl. nach Wiederholung, der Zusammendruck die originalgetreue Wiedergabe zeigt, werden die Lichtdruckfilm@e schwarz eingewalzt und diese dann nach dem Trocknen der Farbe als Diapo@si-.tive für den Farbentiefdruck verwendet.Process for the production of three- or multi-color gravure images using color corrected film photographic printing plates The hitherto The usual way of producing three- and multi-color gravure images takes place in the way that after the colored original first color separations in half-tone on dry plates be made. The resulting partial negatives are then assigned to the color values Corrected the original accordingly and then made slides. After this Once these slides have been retouched, copies are made on pigment paper and transferred to the copper roller. Make after the etching of the copper roller cumbersome and difficult operations required in the manufacture pass the test prints and the revision of the copper cylinder. In most of them In some cases, the proofs are far from the original. The deviation in: The colors are so significant that they can be replaced by a revision of the Kup-P; which can only be done within very modest limits cannot be remedied. In such Cases need. new rollers are etched, having previously corrected the negatives and new slides have been made. The second etchings also show then often not the correct picture, so that the work steps have to be repeated are. The new process for the production of three- or multi-color gravure images circumvents these difficulties by making slides according to their Copy inevitably produce intaglio etchings with the correct color value. One puts in As is known, color extracts in halftone fashion, which make the retouching ever . A Fihnlichtdruckplatte copied and in a known manner for the hand press be made ready for printing. If, possibly after repetition, the overprint the If the reproduction is true to the original, the collotype films @ e are rolled in black and then after the ink has dried as Diapo@si-.tive for color intaglio printing used.
