Definitions

  • the invention relates to a method for obtaining a printed security core for identity documents.
  • the process of the present invention is based on partial stratification in several layers or strata of security prints such as guilloche / watermarks.
  • the invention also relates to a corresponding security printed core.
  • the identity documents existing in the market currently have a paper or plastic foil core.
  • the nucleus is the bearer of both the personal data of the holder of each identity document (filiation data, facial image, signature etc.), as well as security impressions that in the form of guilloche / watermarks in color they are made as protection of said personal data and in order to confer to the document not only an aesthetic and harmonic appearance but also the security that a banknote commonly has.
  • the covers are usually made of polyester-polyethylene mostly in identity documents with a paper core.
  • counterfeiters attack all types of documents and identity cards trying to fraudulently manipulate their core. Particularly, they try to replace the facial image of their headline originally printed on it, either by any type of printing or by photosensitization if the core is photographic paper.
  • security prints of guilloche and color watermarks of all current identity documents on the market are made by printing all the colored lines of said guilloche and precision watermarks on the same single plane or surface of the core.
  • the core is comparable to a banknote with the printed personalization of the personal data of the holder thereof. This is also observed in identity documents whose core is photographic paper. All of them have the disadvantage that in fraudulent attempts to separate their layers and delaminate the protective covers by applying heat and chemical reagents, they can separate the printed core with the safety guilloches intact and with personal data also without damage.
  • the invention relates to a method of producing a printed security core for identity documents, for example identity cards, visas, passports and credit cards, said core having a security print, preferably a color security print. .
  • a first part of said color security print is printed on a first surface; in a second step, transparent and translucent binder is deposited only on predetermined areas of said surface; in a third step, it is printed on said surface, including the preset areas on which binder has been deposited, a second part of said color security print, said second part being complementary to said first part, so that said second part and said first part in combination constitute the security print in color.
  • the invention also relates to a security printed core for identity documents, said core having a security print, preferably a color security print.
  • a security print preferably a color security print.
  • a first part of the color security print is printed on a first surface of a base core.
  • a transparent and translucent binder is deposited only on predetermined areas of said surface (and, therefore, on the corresponding parts of the first part of the color security print).
  • a second part of said color security print is printed on said surface, including the pre-set areas on which the binder is deposited. Said second part is complementary to said first part, so that said second part and said first part in combination constitute the security print in color.
  • the invention also relates to a core obtained by the process of the invention.
  • printing of the security impression (which may comprise color security watermarks / guilloches, etc.) is provided in two differentiated layers on the core, printing part of the security print (for example, lines of the total guilloche / filigree with certain colors) on a surface of the base core of the document, and making a deposit of a transparent and translucent binder only in predetermined areas of one or both sides of the core and then printing the remaining part of the Security print (for example, all remaining lines with their respective specific colors that complete the total guilloche / filigree) over the entire surface even over areas with binder deposit.

  • the core Depending on whether the core is applied for one type or another of an identity document, it will be treated with binder deposit and security impressions, a single face of said base core or both sides.
  • the base core can be paper or plastic.
  • the preset areas of the base core surface on which binder is deposited have any geometric shape to choose from (for example, straight or curved stripes, logos, shields, legends etc.) but so that they have optimum efficacy in the safety of the core and therefore of the identity document, said preset areas should not cover more than 25% to 30% of the surface of each face of the base core.
  • the binder that is applied over these areas can be, for example, selected from (I) pure gelatin, (II) a binder that is made up of polyacrylate polymers, (III) a binder that is made of synthetic polyamides, (IV) a polyolefin binder, (V) a composition that includes at least two binders chosen from (I) -

  • the core can be customized by printing personalization data corresponding to the holder, that is, personal data such as the date of birth or other identification number, signature and facial image.

Abstract

Procédé de production d'un noyau d'impression de securité pour documents d'identité, par exemple des cartes d'identité, des permis, des passeports et des cartes de crédit, ainsi que le noyau correspondant. Au cours d'une première étape, on imprime une première partie (2, 3) d'une empreinte de sécurité en couleur sur une première surface (1') d'un noyau de base (1). Ensuite, au cours d'une deuxième étape, on dépose un agent de liaison (4) transparent et translucide uniquement sur des zones prédéterminées de ladite surface (1'). Au cours d'une troisième étape, on imprime sur ladite surface (1') et sur l'agent de liaison (4) déposé dans les zones prédéterminées une seconde partie (2', 3', 5) de ladite empreinte de couleur de sécurité. La seconde partie (2', 3', 5) est complémentaire de la premiére partie (2, 3) de sorte que la seconde partie (2', 3', 4) et la première partie (2, 3) forment, combinées l'une à l'autre, l'empreinte de sécurité en couleur (2', 3', 5).
