Valuable Document, Method For Producing Same And Printer

Patent No. EP3459758 (titled "Valuable Document, Method For Producing Same And Printer") was filed by Gieseckedevrient Currency Technology on Sep 19, 2018. The application was issued on Nov 9, 2022.

Patent Summary

Method for producing a document of value, such as a banknote, using magnetically orientable effect pigments. The method involves applying a magnetic field to selected areas of the pigment coating while it is in liquid form, thereby changing the orientation of the magnetic particles. The magnetic field is generated using a dynamic optical modulation device, such as a digital micromirror device (DMD), liquid crystal on silicon (LCoS), or liquid crystal display (LCD), which can produce high-resolution patterns of magnetic field intensity. The resulting document features security elements with effects that depend on the viewing angle, which cannot be reproduced even with modern copiers.
