SHEET HAVING A REFLECTIVE ANTI-COUNTERFEITING DEVICE

摘要

A method for the manufacture of a sheet element 1 e.g. a security document or bank note having a reflective anti-counterfeiting device 2 comprises the steps of applying a continuous band of a foil material in the form of a repetitive pattern to a portion of the surface of the sheet element and over- printing at least a part of the foil material with a security tint 3. Hot foil stamping or a similar method such as a transfer process applies a metallic foil or similarly reflective film on to a surface of the material to be used for printing a security document.
