  • the see-through region 80 is not formed by straight but by curved, equidistant cut lines 82.
  • the laser power of the cutting laser was lowered below the cutting threshold of the polymer substrate 20, so that no cutting lines were produced there.

Abstract

L'invention concerne un support de données, en particulier un document de valeur, tel que des billets de banque, des cartes d'identité et analogues, doté d'un substrat (20) en un matériau polymère, qui présente une zone à motif (12) ayant une impression visuelle modifiée sous la lumière incidente et/ou traversante, la zone à motif (12) présentant des perforations (22) partielles ou complètes, tactilement décelables, du substrat et étant réalisée sous forme d'un modèle, de signes ou d'un codage. Le substrat (20) est revêtu au moins dans la zone à motif, des deux côtés, à chaque fois par une couche de recouvrement (30) polymère.
