Title
(EN) A SECURITY DEVICE
(FR) DISPOSITIF DE SÉCURITÉ
Abstract
(EN)
As security device (1) for use in security documents. The security device comprises a substrate (2) having a first surface (3) and second surface. At least the first surface is provided with a plurality of printed regions (4). The printed regions are only visible under ultra violet light. The printed regions comprise inks that fluoresce under ultra violet light. The inks are provided on printed striped regions (4) in varying tonal densities such that when striped printed regions (4) are viewed under ultra violet light they produce a continuous spectrum of colours having diffuse boarders between the different colours or a rainbow.
(FR)
L’invention concerne un dispositif de sécurité (1) destiné à être utilisé avec des documents de sécurité. Le dispositif de sécurité comprend un substrat (2) doté d'une première surface (3) et d'une seconde surface (4). Au moins la première surface est pourvue d'une pluralité de zones imprimées (4). Les zones imprimées ne sont visibles que sous lumière ultraviolette. Les zones imprimées comprennent des encres qui émettent une fluorescence sous lumière ultraviolette. Les encres sont disposées sur des zones de bandes imprimées (4) dans des densités tonales variables de telle sorte que lorsque des zones de bandes imprimées (4) sont visualisées sous lumière ultraviolette, elles produisent un spectre continu de couleurs comportant des frontières diffuses entre les différentes couleurs ou un arc-en-ciel.
