Abstract
(EN)
A security document or device having a first array of dots or lines having a predetermined number of lines per centimetre and a predetermined screen angle, a second array of dots or lines applied to or produced by a separate device and producing a grey scale visible effect, said second array being capable of being superimposed over the first array and having a different number of lines and screen angle calculated from the number lines and screen angle of the first array to produce a visible moiré pattern when the arrays are superimposed to establish the authenticity of the document or device.

L'invention concerne un document ou un dispositif de sécurité comportant un premier ensemble de points ou de lignes, avec un nombre prédéterminé de lignes par centimètre, et un angle de trame prédéterminé, et un deuxième ensemble de points ou de lignes appliqués ou produits par un dispositif séparé et produisant un effet visible de gamme de gris. Ce deuxième ensemble peut être superposé sur le premier ensemble et comporte un nombre de lignes et un angle de trame différents calculés à partir des lignes et de l'angle de trame du premier ensemble pour produire un motif moiré visible lorsque les ensembles sont superposés pour établir l'authenticité du document ou du dispositif.
