Description
Verfahren zur Erzeugung von Kopiervorlagen für Druckformen. Die Erfindung bezieht sich auf ein Ver fahren zur Erzeugung von Kopiervorlagen für Druckformen.
Es sind Verfahren bekannt, bei welchen zur Erzeugung von Kopiervorlagen der Schrift satz durch entsprechende Vorbehandlung der art präpariert wird, dass derselbe ein Nega tiv darstellt. Von diesem Schriftsatz werden durch photographische Aufnahme positive Bilder der Schriftzeichen hergestellt, die als dann mit den auf bekannte Weise erzeugten Diapositiven von den Bildern zu einer ge neinsamen Schriftzeichen und Bilder enthal tenden Montage zusammengestellt, kopiert und geätzt werden. Der Nachteil dieses Ver fahrens besteht darin, dass von Schriftzeichen und Bildern getrennte Aufnahmen gemacht werden müssen, die dann nachher zusammen gestellt werden, was einen wesentlichen Ma terial- und Zeitverlust zur Folge hat.
Davon unterscheidet sich das Verfahren gemäss vorliegender Erfindung dadurch, dass man in dein im Schriftsatz für die Bilder freigelassenen Raum das auf einem transpa- renten Träger befindliche Druckbild auf licht reflektierender oder emittierender Unterlage anordnet und alsdann Schriftsatz und Bild gleichzeitig photographiert und daraus eine Kopiervorlage fertigstellt, zum Zwecke, mit- telst einer einzigen Aufnahme eine sowohl Bild als Schrift enthaltende Kopiervorlage zu erhalten.
Dieses Verfahren kann z. B. wie folgt ausgeführt werden: Als Ausgangspunkt dient der Schriftsatz er wird auf bekannte Weise vorbehandelt, so dass er entweder als negative oder auch als positive Schrift erscheint. Die im Schrift satz mit Blindmaterial nicht ausgefüllten Räume für die Abbildungen werden dann mit einer Licht reflektierenden oder emit tierenden Unterlage, wie z. B. Alabaster gips, oder einer mit einer phosphoreszie renden Substanz durchsetzten Unterlage belegt. Auf diese Unterlage werden die auf einem transparenten Träger befindlichen Druckbilder, also die Negative oder Diaposi tive von den Abbildungen auf das gleiche Niveau wie das Bild des Schriftsatzes ein gesetzt.
Als Negative und Diapositive könn ten auch Drucke, Zeichnungen aufgelegt werden. Alsdann werden Schriftsatz und Bild gleichzeitig eventuell unter Verwendung eines Rasters photographiert und daraus eine Kopiervorlage fertiggestellt. Es werden also auf diese Weise negative oder positive Kopier vorlagen von den Schriftzeichen und Bildern in einer Aufnahme hergestellt.
Process for generating master copies for printing forms. The invention relates to a process for the generation of master copies for printing forms.
Processes are known in which, for the generation of master copies, the font set is prepared by appropriate pretreatment in such a way that it represents a negative. From this document positive images of the characters are produced by photographic recording, which are then compiled, copied and etched together with the slides produced in a known manner from the images to form a common characters and images containing montage. The disadvantage of this method is that separate recordings have to be made of characters and images, which are then put together afterwards, which results in a significant loss of material and time.
The method according to the present invention differs from this in that in the space left free in the typesetting for the images, the print image located on a transparent carrier is arranged on a light-reflecting or emitting base and then the type and image are photographed simultaneously and a master copy is made from them, for the purpose of obtaining a master copy containing both image and writing by means of a single recording.
This method can e.g. B. can be carried out as follows: The starting point is the writing, it is pretreated in a known way so that it appears either as negative or positive writing. The spaces for the images that are not filled in the font set with dummy material are then covered with a light-reflecting or emitting substrate, such as. B. Alabaster plaster, or a document interspersed with a phosphoreszie-generating substance occupied. On this base, the printed images located on a transparent carrier, ie the negatives or slides of the images, are set on the same level as the image of the brief.
Prints and drawings can also be used as negatives and slides. The font and image are then photographed simultaneously, possibly using a grid, and a master copy is made from them. So there are negative or positive copy templates made of the characters and images in one recording.
