More Information
Summary:The present disclosure concerns a multi-spectral image printing method. The method includes the steps of: - providing a multi-spectral image; - providing a material; - determining changes in a refractive index value of the material permitting to reproduce the multi-spectral image when the material is illuminated; and - generating the changes in refractive index value in the material. La présente invention concerne un procédé d'impression d'image multispectrale. Le procédé comprend les étapes consistant à : - utiliser une image multispectrale; - utiliser un matériau; - déterminer des variations d'une valeur d'indice de réfraction du matériau permettant de reproduire l'image multispectrale lorsque le matériau est éclairé; et - générer les variations de valeur d'indice de réfraction dans le matériau.
