Title (EN) MULTI-COLORED SYMBOLOGY METHOD AND APPARATUS
(FR) PROCEDE ET APPAREIL POUR SYMBOLOGIE MULTICOLORE
Abstract:
(EN) Multiple colors are used in connection with one or more encoded symbols to increase the information density of the encoded symbols. The multiple colors can be used to form linearly independent encoded symbols that are overlayed on top of each other to form a composite encoded symbol. The linearly independent encoded symbols may be used to designate different types of information, or can designate separate levels of information in which certain levels can have restricted access. Alternatively, the multiple colors can be used to form a single linearly dependent encoded symbol in which the selected combination of colors defines data states of corresponding elements of a one or two dimensional matrix. Registration marks are used to insure proper print registration of the differently colored elements to insure linear dependency. In either embodiment, the colors can be distinguished using electro-optical imaging techniques.
(FR) De multiple couleurs sont utilisées en liaison avec un ou plusieurs symboles codés en vue d'accroître la densité informative des symboles codés. Ces couleurs multiples peuvent s'utiliser pour former des symboles codés à indépendance linéaire, qui sont superposés pour former un symbole codé composite. Ces symboles codés à indépendance linéaire peuvent s'utiliser pour désigner différents types d'informations, ou bien peuvent désigner des niveaux séparés d'informations dans lesquels certains niveaux peuvent faire l'objet d'un accès restreint. En variante, les couleurs multiples peuvent s'utiliser pour former un unique symbole codé à dépendance linéaire, dans lequel l'association choisie des couleurs définit des états de données d'éléments correspondants d'une matrice uni- ou bidimensionnelle. Des repères d'alignement sont utilisés pour assurer un alignement d'impression correct des éléments colorés différemment, et ce, en vue de permettre la dépendance linéaire. Dans chaque mode de réalisation, les couleurs peuvent être distinguées à l'aide de techniques d'imagerie électro-optiques.
