Title (EN) METHOD FOR PRINTING A FLUORESCENT FULL COLOR IMAGE AND PRINTED MATTER OBTAINED
(FR) PROCÉDÉ D'IMPRESSION D'UNE IMAGE POLYCHROME FLUORESCENTE ET MATIÈRE IMPRIMÉE OBTENUE
Abstract:
(EN) The present invention relates to a method printing a fluorescent full colour image to a substrate that contains an optical whitening agent, which when illuminated with UV-light emits blue colour. According to the invention, the blue colour is used as a blue colour component (B) in an additive RGB-colour model. Thereby, only the green (G) and red (R) colour components are printed. Thus a full-colour image may be produced with only two fluorescent printing inks. The method provides an economical and efficient method to print security prints with high quality.
(FR) La présente invention concerne un procédé d'impression d'une image polychrome fluorescente sur un substrat qui contient un agent de blanchiment optique qui émet une couleur bleue lorsqu'il est éclairé avec une lumière UV. D'après l'invention, la couleur bleue fait office de composante chromatique bleue (B) dans un modèle chromatique RVB supplémentaire. Par conséquent, seules les composantes chromatiques verte (V) et rouge (R) sont imprimées. Il est donc possible de produire une image polychrome avec seulement deux encres d'impression fluorescentes. Le procédé constitue un procédé économique et efficace pour imprimer des impressions de sécurité de grande qualité.
