Description

Verfahren zur Herstellung von Holzmaserdruckformen. Um eine künstliche Holzmaserung auf irgendeinem Material hervorzubringen, wird zunächst ein. Bild der betreffenden Maserung auf photographischem Wege hergestellt. Dieses Bild ist aber z. B. auf Holz wegen seiner Aufsaugefähigkeit nicht ohne weiteres übertragbar, da beim übertragen ein verschwommener, undeutlicher Abklatsch der Struktur entstehen würde.Process for the production of wood grain printing forms. To an artificial one Bringing out wood grain on any material will initially be a. Image of relevant grain produced by photographic means. But this picture is z. B. not easily transferable to wood because of its absorbency, because when transferred, a blurred, indistinct copy of the structure occurs would.

Um diesen Übelstand zu beseitigen, wird der Erfindung gemäß das photographische Bild der Maserung in Holz o. dgl. gestochen, und hierbei die Maserungsstruktur durch Auslassen einzelner Bildzwisclhenpunkte so vergröbert, d. h. die Bildpunkte werden in solche Entfernung voneinander gebracht, daß bei der Rückübertragung die ursprüngliche Bildwirkung durch Verfließen bzw. Aneinanderrücken der Bildpunkte in sauberer Ausführung wieder entsteht.In order to remedy this drawback, the invention according to the photographic Image of the grain in wood or the like engraved, with the grain structure through Omission of individual intermediate points in the image so coarsened, d. H. the pixels will be placed at such a distance from one another that when retransmitted the original Image effect by flowing or moving the pixels together in a neat execution arises again.

Hierauf wird von dem so erhaltenen Holzklischee in an sich bekannter Weise ein Abdruck auf galvanischem Wege hergestellt. In der Zeichnung veranschaulicht Abb. i eine aus Bildpunkten i, 2,, 3 und 5, io bestehende Linie der Maserung, wobei durch Kreuze die auszulassenden Bildpunkte angedeutet sind. Wenn alle Bildpunkte .beibehalten werden, so rinnen die durch die Löschpapierwirkurg des Holzes sich ausbreitenden Farbzonen ineinander, wie dies durch die gestrichelten Kreislinien angedeutet ist, so daß ein verschwommenes Bild entsteht. Abb. 2 zeigt die Linie nach Weglassen einzelner Zwischenpunkte. Die sich ausbreitenden Farbzonen rücken lediglich aneinander oder fließen nur so zusammen, daß ein sauberes Bild entsteht. Die Wahl der auszulassenden Bildpunkte richtet sich nach der Größe und der Entfernung der einzelnen Punkte im unveränderten Bilde.The wooden cliché obtained in this way is then known per se Way made an impression by galvanic means. Illustrated in the drawing Fig. I a line of the grain consisting of pixels i, 2, 3 and 5, io, where the pixels to be omitted are indicated by crosses. When all pixels .be retained, they run through the blotting paper effect of the wood spreading color zones into one another, as indicated by the dashed circular lines is indicated, so that a blurred image is created. Fig. 2 shows the line after omitting individual intermediate points. The spreading color zones are moving only to each other or just flow together in such a way that a clean picture is created. The choice of the pixels to be omitted depends on the size and distance of the individual points in the unchanged picture.

Das Maserungsbild wird mit Hilfe des von dem Holzklischee auf galvanischem Wege erzeugten Abdrucks auf das zu bemasernde Material, in der Regel auf Holz, unter Anwendung von Druckfarbe übertragen. Hierbei bleiben alle nicht die Maserung darstellenden Holzstellen von Druckfarbe frei und behalten daher ihr natürliches Aussehen. Aber auch die Maserungsstellen selbst bewahren das Oberflächenaussehen des Holzes, da sie nicht vollständig mit Farbe überzogen sind. Hierdurch wird auch eine vorangehende oder nachträgliche Beizung des Holzes ermöglicht, was bei Verwendung von Maserungspapier, das die ganze Holzoberfläche bedeckt, ausgeschlossen ist.The grain pattern is galvanized with the help of the wooden cliché Paths produced an imprint on the material to be fabricated, usually on wood, under Applying ink transfer. All that do not show the grain remain Wood areas are free from printing ink and therefore retain their natural appearance. but the grain areas themselves also preserve the surface appearance of the wood they are not completely covered with paint. This also makes a previous one or subsequent staining of the wood, which is possible when using grain paper, that covers the entire wood surface is excluded.

PATENTANSPRUCH: Verfahren 'zur Herstellung von Holzmaserdruckformen, dadurch gekennzeichnet, daß das photographische Bild der Maserung in Holz o. dgl. gestochen wird und hierbei einzelne von den die Maserung ergebenden Bildpunkten ausgelassen werden, worauf von dem so erhaltenen Holzklischee in an sich bekannter Weise ein Abdruck auf galvanischem . Wege erzeugt wird.
