Description

Verfahren zur Herstellung von Rasterdruck-Stereoskopbildern. Im gewöhnlichen Rasterdruckverfahren (Autotypie, Tiefdruck o. dgl.) hergestellte Stereoskopbilder haben den Nachteil, daß sie, bei entsprechender Vergrößerung im Stereoskop betrachtet, dadurch stark störend beeinflußt werden, daß das Korn oder die Linien des verwendeten Rasters stark hervortreten, weil sich die Lichter und Tiefen beider Bilder decken, wodurch die Bildwirkung erheblich gestört wird, so daß das Bild nicht als eine geschlossene Fläche, sondern stark netzartig oder verschleiert erscheint.Process for the production of raster print stereoscopic images. In the ordinary Raster printing process (autotype, gravure or the like) produced stereoscopic images have the disadvantage that when viewed in a stereoscope with the appropriate magnification, are strongly affected by the fact that the grain or the lines of the used Raster stand out because the lights and depths of both images coincide, whereby the picture effect is considerably disturbed, so that the picture does not appear as a closed one Surface, but appears strongly reticulated or veiled.

Zweck der Erfindung ist, bei sogenannten Halbton- (Autotypie-, Tiefdruck- o. dgl.) Bildern eine Bildwirkung zu erzielen, die das stereoskopische Bild in der Vergrößerung genau so harmonisch und plastisch wirken läßt, wie ein Halbtonbild ohne Raster bzw. beim Betrachten eilfies mittels Rasterdruck hergestellten Stereoskopbildes die Rasterwirkung nach Möglichkeit aufhebt oder ausgleicht. Um dies zu erreichen, verfährt man bei im Rasterdruckverfahren herzustellenden Stereoskop-Bildern derart, daß man die einzelnen der sich bei der Betrachtung im Stereoskop ergänzenden Bilder mittels verschiedenartiger oder verschiedenartig gestellter Raster kopiert. Beispielsweise kann man zu dem einen Bilde einen Raster nehmen, dessen Linien horizontal und vertikal laufen, während man zu dem anderen einen solchen verwendet, dessen Linien schräg gestellt sind; oder, zu dem einen Bilde wird ein Linienraster und zu dem anderen ein Kornraster verwendet. Eben durch die Anordnung verschiedenartiger Raster für jedes Bild wird erreicht, daß die Lichter und Tiefen beim Betrachten beider Bilder im Stereoskop ausgeglichen erscheinen, wodurch eine harmonische Bildwirkung mit möglichst geschlossener Farbfläche erzielt wird. Das Bild wirkt als sog. Halbtonbild.The purpose of the invention is to use so-called halftone (autotype, gravure o. Like.) Images to achieve an image effect that the stereoscopic image in the Makes enlargement appear as harmonious and vivid as a halftone image without raster or when viewing eilfies stereoscopic image produced by means of raster printing the grid effect cancels or compensates as far as possible. To achieve this, if one proceeds with stereoscopic images to be produced in the raster printing process, that you can see the individual images that complement each other when viewed in the stereoscope copied by means of different or differently placed grids. For example one can take a grid for one picture, the lines of which are horizontal and vertical run while one uses one with the other one whose lines are oblique are placed; or, one picture becomes a grid of lines and the other a grain grid used. Just by arranging different grids for Each image is achieved that the highlights and shadows when viewing both images appear balanced in the stereoscope, creating a harmonious image effect with as closed a color area as possible is achieved. The image acts as a so-called halftone image.
