Abstract

L'invention concerne une utilisation et un procédé pour le contrôle de documents. Jusqu'à présent, des documents à couches de sécurité diffringentes, en particulier des hologrammes, étaient vérifiés en recourant à une technique de contrôle optique coûteuse. Toutefois, l'ensemble du processus de contrôle était d'une durée si longue qu'un tel procédé ne pouvait trouver d'application dans des machines de traitement à grande vitesse. Une possibilité de contrôle rapide représente, en tant que réelle caractéristique, une autre étape de sécurité lors de l'évaluation des couches diffringentes. La couche diffringente présente, dans des plans différents, une couche métallisée discontinue et/ou des couches partiellement métalliques et/ou des zones de couches métalliques. On connaît divers procédés de mesure faisant intervenir une conductivité électrique. Dans la pratique, le procédé de mesure capacitif, sans contact, s'est révélé comme étant d'une meilleure faisabilité.
