Description

  

  Verfahren zur     lierstellulig        Yon    gerasterten     Tiefdruckformen.       Das vorliegende Verfahren zur Herstel  lung von     gerastert#en    Tiefdruckformen soll  dazu dienen, ohne     Kop;-ren    durch einen be  sonderen Raster Tiefdruckformen     lierzu-          stellen.    Die Rasterlinien sollen vielmehr  einen Bestandteil der Druckplatte bilden.

    Die Herstellungsweise ist zum Beispiel fol  gende:  Auf durchsichtige Platten aus     Zellon,     Zelluloid und dergleichen wird auf be  kannte Art durch Prägen, Formen, Aufkle  ben oder Aufgiessen ein wasserfestes     Relief-          Tiefdruckraster    aufgebracht, in der Weise,       dass    zwischen den erhabenen     Rasterlinieu     Vertiefungen in     cler    Platte liegen. Diese  Vertiefungen werden bis     zur    Höhe. der er  habenen Rasterlinien mit     Chromatgelatine     ausgefüllt.

   Die     Chromatgelatine    wird von  unten belichtet,     (l.   <B>11.</B> das Diapositiv des zu  kopierenden Bildes wird auf der Rückseite  der durchsichtigen Platte angelegt, so     dass     das Licht durch das Diapositiv und durch  die durchsichtige Platte in     dio        Chromatgela-          tineschicht    eindringt; hierauf wird die    Platte mit warmem Wasser entwickelt.

         Daboi    bleiben natürlich die Rasterlinien,  die als     Ste,-e    für     Llie        Hakel    dienen sollen,       unveränder[        stelien.   <B>Die</B> einzelnen Teile des       Bilde.s    bleiben,<B>je</B> nachdem die     Chromat-          gelatinenschicht    mehr oder weniger Licht  erhalten hat, höher oder tiefer als gegerbte  Gelatine in den Tiefen zwischen den Raster  linien zurück. so     dass    diese Vertiefungen we  niger oder     inehr    Druckfarbe fassen können,  <B>je</B> nachdem es das Bild erfordert.



  Process for lierstellulig yon screened gravure forms. The present method for the production of screened intaglio printing forms is intended to provide gravure printing forms without copying through a special screen. Rather, the grid lines should form part of the printing plate.

    The production method is, for example, the following: On transparent plates made of cellulose, celluloid and the like, a waterproof relief gravure raster is applied in a known manner by embossing, molding, gluing or pouring, in such a way that depressions in the raised raster lines in the Plate lying. These indentations are up to the height. of the grid lines he had filled in with chromate gelatine.

   The chromate gelatine is exposed from below, (l. <B> 11. </B> the slide of the image to be copied is placed on the back of the transparent plate so that the light through the slide and through the transparent plate in the chromate gel The ink layer penetrates; the plate is then developed with warm water.

         Of course, the grid lines that are supposed to serve as Ste, -e for Llie Hakel remain unchanged. <B> The </B> individual parts of the picture remain, <B> depending </B> after the chromate gelatine layer has received more or less light, higher or lower than tanned gelatine in the depths between the grid lines . so that these depressions can hold less or more ink, <B> depending </B> as the image requires.
