Patent ID: 8137899

Claim:
A data carrier with an optically variable structure comprising: an embossed structure and a print contrasting with the surface of the data carrier, the embossed structure and the print being so combined that at least parts of the print are completely visible upon perpendicular viewing but concealed upon oblique viewing so that a tilt effect arises upon alternate perpendicular and oblique viewing, wherein the total area provided with print and embossed structure is divided into partial areas, wherein the partial areas divide the embossed structure into partial embossed structures, wherein different partial areas are provided with different partial embossed structures, wherein the partial embossed structures comprise embossed lines having flanks that are visible upon certain viewing angles, and wherein the print is a line screen that is constant across all partial areas, wherein the partial areas form two dimensional matrix of visually recognizable partial areas, the partial areas being visually recognizable due to a visual effect of the different partial embossed structures with respect to the print, the matrix having m partial areas in a horizontal direction and n partial areas in a vertical direction, the partial areas of the matrix being directly adjacent, where m, n≧1 and at least one of m and n>1.
