Definitions

  • the invention relates to a method of producing printing surfaces for intaglio printing, which offers as an advantage over the methods hitherto used, the possibility of again using the printin surface after a run or series of impressions, by simply cleaning the printing surface with hot water for the next run or series of impressions, without the necessity for the metal plate or metal cylinder upon which the intaglio printing surface ,0 is formed being ground down or stripped off, as in customary methods, whereby there is on the one hand a substantial saving in material and on the other a number of operations hitherto necessary are dispensed with.
  • the surface of the 35 printing plate or cylinder is first provided with a uniformly deep screen, whereby the surface is divided into very small squares by fine lines.
  • the screen can be applied for example in the known 40 manner by etching.
  • the screen may however be produced by mechanical means, as for example by milling, which may be advantageous for example in the use of printing plates made of steel or similar material.
  • intaglio plates or formes is effected according to the invention by first copying the letterpress and/or images on a film of light sensitive material such as gelatine mounted on paper, the film being of a thickness corre- 50 sponding to the depth of the screen of the printing After beinz suitably softened or soaked such films are pressed down with the film side on the screened copper or other metal plate or cylinder. By treatment with warm water, the film sup- 55 port is removed while the gelatine.
  • a film of light sensitive material such as gelatine mounted on paper
  • the gelatine relief laid in the screen needs only to be washed with hot water after the run and the printing surface can be used again for the next run immediately.
  • the present invention is applicable not only for producing small printing plates but it is particularly suitable for the production of large fiat and cylindrical printing surfaces such as are usually employed in rotary intaglio printing.
  • a method of producing printing surfaces for intaglio printing characterized in that the metal of the printing-surface to be produced is provided with a uniformly deep screen, and in that the letterpress and images are reproduced 'on a light sensitive film mounted upon a suitable support, the film corresponding in thickness to the depth of the screen, whereupon the film after being softened or soaked is pressed down with the film side upon the untreated screened metal surface so that the light sensitive film enters thehollows of the screen, after which the film support is-removed, and the film is developed.
