Abstract

L'invention concerne essentiellement un procédé de fabrication d'un code à barres couleur bidimensionnel comprenant un agencement d'éléments structurels de base colorés codant au moins un élément d'information,ledit procédé de fabrication comprenant les étapes suivantes :- détermination (E304), par des moyens de traitement de données, d'un ensemble d'éléments structurels de base colorés correspondant audit au moins un élément d'information, au moins un élément structurel de l'ensemble comprenant un motif, et- formation (E308) dudit au moins un élément structurel de l'ensemble sur un support, afin de créer l'agencement,dans lequel :- le support comprend une matrice comprenant une pluralité de pixels (226), chaque pixel (226) comprenant au moins deux sous-pixels (228) de couleurs différentes, la couleur étant formée par un dispositif de diffraction de la lumière etet- la formation dudit moins un élément structurel de base coloré comprend une modification du support au niveau d'au moins une partie d'au moins un sous-pixel d'au moins un pixel de la matrice, ladite modification permettant d'obtenir la couleur et le motif dudit au moins un élément structurel de base.The invention essentially relates to a method of manufacturing a two-dimensional color bar code comprising an arrangement of colored basic structural elements encoding at least one element of information, said manufacturing method comprising the following steps: - determination (E304) , by data processing means, of a set of colored basic structural elements corresponding to said at least one information element, at least one structural element of the set comprising a pattern, and- formation (E308) of said at least one structural element of the assembly on a support, in order to create the arrangement, in which:- the support comprises a matrix comprising a plurality of pixels (226), each pixel (226) comprising at least two sub-pixels (228) of different colors, the color being formed by a light diffraction device andand- the formation of said at least one colored basic structural element comprises a modification of the support at least a part of at least one sub -pixel of at least one pixel of the matrix, said modification making it possible to obtain the color and the pattern of said at least one basic structural element.
