Definitions

  • the present invention relates to a novel method for producing printed products with a profiled surface, in particular Braille, which does not require the usual engravings in paper.
  • the invention also relates to a printed product produced by the novel method.
  • This object is achieved according to the invention by a method of the type mentioned at the outset, the characteristic features of which can be seen in the fact that a printing image is first generated on a printing medium in a printing press, and then an expandable granulate which is only applied to the freshly printed printing image the areas fresh from the print are liable for the fact that non-adherent granulate is then removed from the print carrier and that the expandable granulate is inflated in a subsequent last working step.
  • the method according to the invention is carried out in particular with a printing press which works according to the offset method.
  • printing inks are applied to the visible areas of the image that have residual moisture when fresh from the press.
  • the presence of the residual moisture has the effect according to the method according to the invention that the expandable granulate, which is applied in the form of a fine-grained powder, only adheres to the places where the printing ink is, while the fine-grained powder is on the free printing medium (paper) does not stick, but can be easily removed.
  • a mixture of resin and quartz which has a mixing ratio of resin to quartz in the range from 0.1 to 10, preferably from 0.2 to 8, particularly preferably from 0.3 to 7, is used as the expandable granules.
  • the expandable granules can additionally contain customary auxiliaries such as stabilizers, binders, photopoly mers and initiators.
  • the expandable granules are removed from the print carrier, to which there is no adhesion, preferably pneumatically by suctioning off and returning the extracted material to the storage container.
  • careful mechanical removal can also be provided, provided that this is carried out so carefully that too much material is not removed from the image areas to which adhesion is to take place.
  • Any known print carrier can be printed as a print carrier using the method according to the invention.
  • plastic films e.g. for labels, or also metals, e.g. for cans or signs.
  • the expandable granules are inflated, for example, by heat treatment at temperatures in the range from 60 to 200 ° C., preferably in the range from 80 to 180 ° C.
  • the resin melts and combines with the quartz.
  • the swelling can also be triggered by another energy source such as visible light or UV radiation, provided that a suitable initiator is added as an additive to the expandable granulate.
  • the swelling produces profiles with a height in the range from 0.02 to 1 mm, measured from the plane of the paper, preferably from 0.05 to 0.9 mm, particularly preferably from 0.1 to 0.75, by the process according to the invention mm.
  • printed products with any appearance can be produced by the method according to the invention.
  • a line of Braille and a line of optically readable text can be created alternately.
  • the optically readable Characters can be arranged in sync with the letters above or below the characters in Braille, but a non-synchronous representation or a representation in text blocks can also be produced.
  • a printed product according to the inventive method is particularly preferred which has a print on both sides.
  • the font size of the characters in Braille and the font size of the optically readable characters can be set variably. It goes without saying that printed matter can be produced with texts in all possible languages and dialects, which can be easily felt with the fingers of blind or severely visually impaired people and thus decoded from the content. Furthermore, according to the invention, drawings, diagrams or images of products can also be represented, which can be activated by pressing the

Abstract

L'invention concerne un nouveau procédé de représentation de produits imprimés à surface profilée, en particulier d'écriture braille, sans gravures dans le support d'impression. Selon ce procédé, une image imprimée est d'abord produite sur un support d'impression dans une presse. Des granulés gonflants sont ensuite appliqués sur l'image fraîchement imprimée, ces granulés n'adhérant que sur les points fraîchement imprimés. Les granulés n'adhérant pas sont ensuite retirés du support d'impression puis, dans une dernière opération, les granulés gonflants sont gonflés par traitement thermique à des températures comprises entre 60 et 200 °C. Cette invention concerne également un produit d'impression fabriqué selon ledit procédé, lequel produit présente un aspect quelconque et est, de préférence, imprimé des deux côtés.
