发明名称 Security document with security feature
摘要 A security element (9) for a security document (10) comprises a first, second, third and fourth line grid (R1, R2, R3, R4) which contrasts in each case with the substrate surface (0) and is assigned in each case to a pattern (M1, M2, M3, M4) comprising an embossed structure (P1, P2, P3, P4) of the substrate (9). A first, second, third and fourth pattern angle (phi1, phi2, phi3, phi4) differ from one another. A first security information item (I1) is coded as a localized distribution of the first and the second pattern (R1, R2), and a second security information item (I2) is coded as a localized distribution of the third and the fourth pattern (R3, R4). The first and the second security information item overlap here. By way of an arrangement of the first and the second pattern (R1, R2) in first grid cells (RZ1) and by way of an arrangement of the third and the fourth pattern (R3, R4) in second grid cells (RZ2), and by way of an alternating arrangement of the first and second grid cells, specific intensity distributions which can be used for examining the authenticity result from different viewing directions (A, B, C, D) of the security document.
