Title (EN) PRINTING OF SECURITY FEATURES
(FR) IMPRESSION D'ÉLÉMENTS DE SÉCURITÉ
Abstract:
(EN) To print a security feature on a medium a method is suggested, comprising inkjet printing an ink including one or more pigments, wherein at least one pigment satisfies the formula (I), and whereas Δρ is the density difference between pigment and ink vehicle; g is the earth acceleration constant; d is the pigment particle diameter D90; kB is the Boltzmann constant; and T is the temperature. Inkjet printing of the ink is performed by a flextensional ink jet print head structure and printing is performed to provide one or more security features on the medium.
(FR) L'invention concerne un procédé destiné à imprimer un élément de sécurité sur un support, consistant à imprimer par jet d'encre une encre comprenant un ou plusieurs pigments, au moins un pigment satisfaisant à la formule (I), et Δρ étant la différence de densité entre le pigment et le véhicule à encre ; g étant la constante d'accélération de la terre ; d étant le diamètre de particule de pigment D90 ; k B étant la constante de Boltzmann ; et T étant la température. L'impression par jet d'encre de l'encre est effectuée par une structure de tête d'impression par jet d'encre flextensionnelle, et l'impression est effectuée en vue de fournir un ou plusieurs éléments de sécurité sur le support.
