Description

Verfahren zur Herstellung von Zweifarbendruckformen für Farben mit verschiedenen Bindemitteln In der Zeitschrift für Reproduktionstechnik (Jahrgang 1900, Seite 48) ist ein Herstellungsverfahren für eine Druckform, die ein gleichzeitiges Einwalzen und Drucken von zwei Farben gestattet, erwähnt, wonach die Farbe gbgebenden Elemente einer Hochdruckform nach dem lithographischen Prinzip derartig behandelt werden, daß bestimmte willkürlich begrenzte Teile derselben beispielsweise nur Wasserfarbe und die resjtlichen. Teile nur Fettfarbe annehmen. Das beschriebene Verfahren beschränkt sich aber nur auf die rein manuelle Überführung von normalen Buchdruck-Zinkklischees in Zweifarbendruckformen, während eine Herstellungsweise solcher Druckformen nach farbigen Vorlagen unter Mitbenutzung photomechanischer Mittel, wie nach vorliegender Erfindung, nicht erklärt ist. Das Verfahren nach der Erfindung kann auf jedes geeignete Material für Zweifarbendruckformen, wie Zink, Kupfer, Messing, Aluminium, Lithographiestein, angewendet werden umd bietet durch die Einführung photomechanischer Methoden Vorteile.Process for the production of two-color printing forms for colors with various binders In the magazine for reproduction technology (volume 1900, page 48) is a manufacturing process for a printing form that has a simultaneous Rolling in and printing of two colors permitted, mentioned, after which the color gives Elements of a letterpress form treated in this way according to the lithographic principle be that certain arbitrarily limited parts of the same for example only water color and the rest of the world. Parts only take on fat color. The procedure described is limited but only on the purely manual transfer of normal letterpress zinc plates in two-color printing forms, while a production method of such printing forms according to colored templates with the use of photomechanical means, as according to the present one Invention, is not explained. The method of the invention can be applied to any suitable Material for two-color printing forms, such as zinc, copper, brass, aluminum, lithographic stone, be applied and offers advantages through the introduction of photomechanical methods.

Als Ausführungsbeispiel für die photomechanische Herstellung einer Zweifarbendruckform nach zweifarbiger Vorlage mit Farbenübergängen sei folgendes angegeben. Um alle für die zwei Farben notwendigen Druckelemente als gemeinsame Hochdruckform druckfähig von den nichtdruckenden Teilen der Druckplatte zu isolieren, werden die unter Benutzung von Farbfilter und Raster gemachten Reproduktionsaufnahmen unter Einhaltung genauer Paßmarken in zeitlicher Aufeinanderfolge übereinander auf dieselbe Stelle eines lichtempfindlichen, Druckmusterträgers kopiert und die so erhaltene Kopie, wie auch sonst bei Autotypien bekannt, hochgeätzt. Die nun für die Aufnahmefähigkeit der entgegengesetzt gerichteten Farben notwendige photomechanische Spaltung der Abdruckelemente wird nach dem Entsäuern und wieder Lichtempfindlichmachen der Druckform durch das nochmalige an dieselbe Stelle Kopieren einer der beiden Reproduktionsaufnahmen mit nachfolgender Behandlung der Kopie im Sinne des Flachdrucks erreicht.As an embodiment for the photomechanical production of a Two-color printing form based on a two-color template with color transitions is the following specified. To all printing elements necessary for the two colors as common To isolate the letterpress form in a printable manner from the non-printing parts of the printing plate, are the reproduction recordings made using color filters and grids in compliance with exact passport marks in chronological order on top of each other copied the same place of a light-sensitive, print sample carrier and the like Preserved copy, as is otherwise known from autotypes, highly etched. The now for the ability to absorb the oppositely directed colors is necessary photomechanical Cleavage of the impression elements will after deacidification and make photosensitive again the printing form by copying one of the two again to the same place Reproduction recordings with subsequent treatment of the copy in the sense of planographic printing achieved.

Obwohl Korrekturen bei Druckformen mach der Erfindung möglich sind., wird man diese jedoch bei gerasterten Bildern zu umgehen suchen und im Interesse einer möglichst glatten Herstellung des Druckmusters mach dem indirekten Verfahren, d. h. über die Retusche der Positive und Negative, arbeiten, wobei die sogenannten photographischen Andruckverfahren (s. z. B. Zeitschrift Deutscher Drukker, Sept.-Heft 26) sehr gute Dienste leisten können.Although corrections in printing forms are possible according to the invention, one will try to bypass these in the case of rasterized images and, in the interest of producing the printing pattern as smoothly as possible, use the indirect method, ie the retouching of the positives and negatives, the so-called photographic Proof processes (see e.g. magazine Deutscher Drukker, September issue 26) can provide very good service.
