A substrate comprises a first layer of material and at least a first opaque layer (3) of material covering partially or totally the first layer of material. The first layer has at least two adjacent zones (1,2) of a different color. The element further comprises a pattern (4) formed by a partial engraving of said opaque layer (3). The pattern (4) extends at least partially on each of said zones (1,2) so that the pattern (4) comprises adjacent parts of different color in perfect register apparent through said opaque layer (3).

L'invention porte sur un élément de sécurité pour un support de données tel que des billets de banque, des titres, des chèques, des cartes de crédit, des cartes d'identité et autres documents identiques. Un substrat comprend une première couche de matériau et au moins une première couche opaque (3) de matériau recouvrant en partie ou en totalité la première couche de matériau. La première couche présente au moins deux zones adjacentes (1,2) de couleur différente. L'élément comporte aussi un motif (4) formé par gravure partielle de ladite couche opaque (3). Le motif (4) s'étend au moins en partie sur chacune desdites zones (1,2) de manière que le motif (4) comprenne des parties adjacentes de couleur différente dans un registre parfait visible à travers la couche opaque (3).
