Abstract

La présente invention concerne le domaine et des procédés et appareils d'impression destinés à produire, sur un substrat, des couches à effet optique (oel) comprenant des particules de pigment magnétiques ou magnétisables en forme de plaquette orientées magnétiquement. En particulier, la présente invention concerne des procédés utilisant des appareils d'impression comprenant un premier dispositif de génération de champ magnétique monté sur un dispositif de transfert (td) et un second dispositif de génération de champ magnétique statique destiné à produire lesdites oel en tant que moyen anti-contrefaçon sur des documents de sécurité ou des articles de sécurité ou à des fins décoratives.The present invention relates to the field and printing methods and apparatus for producing, on a substrate, optical effect layers (oels) comprising magnetic or magnetizable wafer-shaped pigment particles. In particular, the present invention relates to methods using printing apparatuses comprising a first magnetic field generating device mounted on a transfer device (td) and a second static magnetic field generating device for producing said oels as as an anti-counterfeiting means on security documents or security articles or for decorative purposes.
