  • the variation takes place again in a regular grid, so that, for example, the depressions have alternately different depths. Of course, more than two depths can be realized.
  • a structured sonotrode can also be used. This also has a plurality of bulges in a corresponding geometric configuration analogous to Figures 7a to 7g.
  • ultrasound is coupled into the sonotrode so that the surface is locally heated and the sonotrode penetrates into the surface 19 and forms the depressions 14.
  • protrusions 41 have a laminating sheet or a sonotrode
  • Projections can be formed analogously to the shapes of the wells by means of different geometries.

Abstract

L'invention concerne un procédé permettant de produire un document de sécurité individualisé (90) comprenant les étapes consistant à : fournir plusieurs couches de substrats ; réunir les couches de substrats pour obtenir un empilement de couches de substrats ; stratifier les couches de substrats réunies dans l'empilement de couches de substrats pour obtenir un corps de stratification ; fournir un dispositif d'impression numérique ; imprimer au moins une zone de marquage d'une surface extérieure (19) du corps de stratification (11) au moyen du dispositif d'impression numérique pour la mise en mémoire d'informations d'individualisation (18). Une microstructuration présentant une pluralité d'évidements (14) est ménagée dans le corps de stratification (11) avant l'impression dans l'une des surfaces extérieures (19) dans la ou les zones de marquage (7), et l'impression est effectuée de sorte qu'une partie de l'encre imprimée pénètre dans les évidements (14).
