Description
Verfahren zur Herstellung von Teilfarbenplatten für den Farbendruck Die Erfindung besteht .in einer Abwandlung des Verfahrens nach Patent 585 323, in welchem das Wesentliche die Herstellung von Teilfarbenplatten für Farbendruck mit Hilfe von Glasplatten (Filmen) ist, die mit einer farbaufsaugenden Schicht versehen sind. Die Schicht wird angefeuchtet, so daß sie zum Quellen kommt, sodann mit zweckmäßig lichtechter Eiweißlasurfarbe mit dem gleichen Bild in je einer Farbe bemalt. Danach werden dann die entsprechenden Druckplatten für Ein- oder Mehrfarbendruck angefertigt.Process for the production of partial color plates for color printing The invention consists in a modification of the method according to patent 585 323, in which is the essence of the manufacture of partial color plates for color printing with The help of glass plates (films) is provided with a paint absorbent layer are. The layer is moistened so that it comes to swell, then with expedient lightfast egg white glaze paint with the same picture each painted in one color. Thereafter the corresponding printing plates for single or multi-color printing are then made.
Das Verfahren gestattet die einwandfreie Herstellung von farbigen Bildern. In manchen Fällen ist es jedoch erwünscht, den Umriß genauestens wiederzugeben. Diese Forderung wird z. B. erhoben bei. der Herstellung von Abbildungen von Antiquitäten, Keramiken, metallenen Gegenständen in Katalogen usw. Hier genügt häufig die Wiedergabe, auch wenn eine Bleistiftskizze für die zu bemalende Glasplatte benutzt wird, nicht.The process allows the perfect production of colored Images. In some cases, however, it is desirable to accurately reproduce the outline. This requirement is z. B. collected at. the production of images of antiques, Ceramics, metal objects in catalogs, etc. even if a pencil sketch is used for the glass plate to be painted, not.
Hier kann man erfindungsgemäß entweder so vorgehen, daß man die Grundformen direkt auf die mit der farbaufsaugenden' Schicht versehenen Glasplatte zeichnet, oder indem man als Grundplatte ein photographisches Diapositiv wählt, dem dann die nichtphotographischen Farbplatten hinzugefügt werden. In der ersten Form der Übertragung erhält man zwar keine photographische Genauigkeit, jedoch wird infolge der Ersparnis einer Übertragung, wie sie sonst durch Pause und Photographie z. B. bei der Herstellung des Druckes nach einer Federzeichnung notwendig wird, ein Teil der Fehlerquellen ausgeschaltet und somit eine wesentlich einfachere und klarere Konturwiedergabe erzielt. Zu beachten ist dabei, daß die Möglichkeit besteht, auf der Platte auch ohne Anfeuchtung der Schicht mit Tusche zu arbeiten, da die Farbe (Tusche) sofort aufgesaugt wird und nicht über der Schicht stehenbleibt. Im zweiten Fall, bei der Wahl eines photographischen Diapositivs als Unterplatte, enthält dieses die genaue Form. Es wird für die benötigte Ätzung retuschiert. Das hiervon hergestellte Klischee wird in der jeweils gewünschten Grundfarbe gedruckt, während die übrigen Farben aus den gemalten Farbplatten entstehen. Diese Kombination ermöglicht photographisch genaue Wiedergabe, ohne daß Farbverfälschungeti eintreten, die bei den bisher üblichen Verfahren stets mehr oder minder vorhanden waren, weil die photographischen Farbplatten auch bei genauester Retusche in der Farbwirkung nicht vorauszubestimmen 'sind.Here you can either proceed according to the invention in such a way that the basic shapes draws directly on the glass plate provided with the paint-absorbing layer, or by choosing a photographic slide as the base plate, to which the can be added to non-photographic color plates. In the first form of transmission photographic accuracy is not obtained, but is saved as a result of the savings a transmission, as it is otherwise due to pause and photography z. B. in manufacture of the print after a pen drawing becomes necessary, part of the sources of error switched off and thus a much simpler and clearer contour reproduction achieved. It should be noted that there is also the possibility of using the plate work with Indian ink without moistening the layer, as the color (Indian ink) immediately is absorbed and does not remain over the layer. In the second case, the If you choose a photographic slide as a sub-plate, it will contain the exact number Shape. It is retouched for the required etching. The cliché produced by this is printed in the desired basic color, while the other colors emerge from the painted color plates. This combination enables photographic exact reproduction without color falsifications occurring with the previously usual Procedures were always more or less available because the photographic color plates Even with the most precise retouching, the color effect cannot be determined in advance.
