Description
Verfahren zur Herstellung von Raumbildern Die bekannten Raumbilder erfordern zu ihrer Betrachtung eine sehr helle Beleuchtung, so daß sie beispielsweise in Schulen fürUnterrichtszwecke nur benutzbar sind, wenn besonders günstige Lichtverhältnisse vorliegen. Selbstverständlich ist es aber erwünscht, daß die Raumform der Bilder beim Betrachten mit der üblichen zweifarbigen Brille selbst dann möglichst klar in Erscheinung tritt, wenn die meistenteils vorhandene mäßige Beleuchtung vorhanden ist. Das einfachste bekannte Verfahren zur Herstellung von Raumbildern besteht darin, daß die beiden Teilbilder, beispielsweise in einer roten und einer blaugrünen Farbe auf weißem Grunde übereinandergedruckt werden (Komplementärfarben). Beim Betrachten eines solchen Raumbildes mit einer rotblaugrünen Brille tritt das blaugrüne Restbild selbst dann noch deutlich, also störend hervor, wenn die Lichtverhältnisse besonders günstig sind. Gemildert, aber immer noch nicht befriedigend, ist die Wirkung auch dann, wenn das Übereinanderdrucken der beiden Teilbilder auf leicht gefärbtem Grund oder in der Weise erfolgt, daß der verbliebene weiße Grund in einer Mischfarbe bedruckt wird.Process for the production of spatial images The known spatial images require very bright lighting for viewing them, so that, for example can only be used in schools for teaching purposes if the lighting conditions are particularly favorable are present. Of course, it is desirable that the spatial form of the pictures when viewed with the usual two-tone glasses even then as clearly as possible occurs when the mostly moderate lighting is present is. The simplest known method for producing spatial images is to that the two partial images, for example in a red and a blue-green color are printed on top of each other on a white background (complementary colors). When looking at Such a spatial image with red-blue-green glasses appears the blue-green residual image even then still clearly, so disturbing, when the lighting conditions are particularly good are cheap. The effect is also milder, but still not satisfactory when the two partial images are overprinted on a lightly colored background or takes place in such a way that the remaining white ground is printed in a mixed color will.
Die nach diesen Grundsätzen angefertigten Raumbilder erfordern beim Betrachten, um den Stereoeffekt gut zustande kommen zu lassen, eine außergewöhnlich helle Beleuchtung. Je heller aber die Betrachtung ist, um so stärker, also störender, tritt das Restbild in Erscheinung das den Stereoeffekt beeinträchtigt.The room images prepared according to these principles require the To make the stereo effect work well, consider an extraordinary bright lighting. But the brighter the view, the stronger, i.e. more disturbing, the residual image appears, which affects the stereo effect.
Für Unterrichtszwecke in Schulen sind diese Bilder aus den angegebenen Gründen nur bei genau abgestimmter Beleuchtung mit Gewinn benutzbar.For educational purposes in schools these images are taken from the ones given Reasons can only be used profitably with precisely coordinated lighting.
Erfindungsgemäß wird die störende Wirkung des Restbildes dadurch beseitigt, daß die komplementärfarbigen Teilbilder auf den entsprechenden Druckplatten so angebracht «-erden, daß sie beim Drucken negative Bilder ergeben, d. h. die das Bild erzeugenden Linien keine Farbe erhalten und nur der Grund farbig gedruckt wird.According to the invention, the disruptive effect of the residual image is eliminated by that the complementary colored partial images on the corresponding printing plates so appropriate "- that they produce negative images when printed, i. H. the the Lines generating the image do not receive any color and only the base is printed in color.
Beide so angefertigten Platten werden mit den Komplementärfarben übereinandergedruckt. Werden hierzu beispielsweise die Farben Rot und Blaugrün verwendet, dann erhalten die Linien des roten Teilbildes, die sich mit den Linien des blaugrünen Teilbildes nicht in Deckung befinden, beim Drucken blaugrüne und die Linien des blaugrünen Teilbildes rote Färbung, wogegen der Grund für beide Teilhilder die Mischfarbe aufweist. Beim Betrachten des Raumbildes verschwinden die Restbilder nahezu vollständig, und soweit sie noch in Erscheinung treten, stören sie den Stereoeffekt nicht.Both plates produced in this way are printed on top of each other with the complementary colors. If, for example, the colors red and blue-green are used for this purpose, then obtained the lines of the red sub-image that merge with the lines of the blue-green sub-image not in register when printing teal and the lines of teal Partial image is red in color, whereas the reason for both partial images has the mixed color. When looking at the spatial image, the residual images disappear almost completely, and as far as they still appear, they do not disturb the stereo effect.
Wesentlich ist, daß beim Betrachten des Bildes der Stereoeffekt gerade bei geminderter Helligkeit gut zur `'Wirkung kommt.It is essential that the stereo effect is straight when looking at the picture comes into effect with reduced brightness.
