The stamping sheet (1) produces documents by means of lamination and/or surface stamping. The stamping process produces recessed structures (3, 7, 8, 9) and raised structures (4, 5, 10, 11) relative to a highly polished surface (6), which serves as a reference zone. The recessed structures are produced in other single-stage this truck during process, which does not affect the surface of stamping sheet not involved in the process. |
