发明名称 Method for production of safety element with optically variable structure, involves providing substrate with marking structure with many flat markings and relief structure with many reflex relief elements
摘要 Method involves providing substrate (40) with a marking structure with many flat markings(24,26) and with relief structure with many reflex relief elements (22) whereby marking structure and relief structure are combined such that different information are visible from different reflection directions. Optically variable structure (20) having individualized character is produced with contact less procedure or print process on solid printing block. Independent claims are included for the following: (1) Safety element; and (2) Application of safety element.
