The invention relates to a method for individualising security documents. According to the inventive method, a printed image (1) which is identical for a group of security documents, is high-quality in terms of security, and is neutral in terms of use, is overprinted with a second printed image individualising the security document (2). The printing ink of the second printed image (2) is repelled by the printing ink of the first printed image (1). The printing ink of the second printed image thus lodges only in the regions of the first printed image in which there is no printing ink of the first printed image. Preferably, the first printed image is produced according to the line gravure printing method, and the second printed image is produced by means of liquid printing ink, especially according to the ink jet method.
Procédé d'individualisation de documents sécurisés selon lequel une image imprimée (1), identique pour un groupe de documents sécurisés, de haute qualité technique concernant la sécurité et neutre du point de vue de l'utilisation est recouverte par surimpression par une seconde image imprimée (2) individualisant le document sécurisé, l'encre d'impression de la seconde image imprimée (2) étant repoussée par l'encre d'impression de la première image imprimée (1). L'encre d'impression de la seconde image imprimée se dépose donc uniquement dans les zones de la première image imprimée qui sont exemptes d'encre d'impression de la première image. De préférence, la première image imprimée est produite par un procédé de photogravure en creux et la seconde image imprimée est produite à l'aide d'une encre d'impression liquide, en particulier selon un procédé à jet d'encre.
