So Clear - So Secure

The secure window in the banknote is a more recent security advance offering many visual and tactile options; it is difficult to counterfeit and very easy to recognize. The combination of different production steps offers outstanding protection against counterfeits.

Transparency, translucency and image transformation. Plus the existing substrate embedded security. Paper banknotes can offer the best of both worlds: Individual windows on a banknote that feature various foil effects or printed implementation, enable users to immediately check note authenticity. To seal the window, we use transparent laminate foils which present additional information when viewed from above, in transmitted light, or held at an angle.The technology and production process represent a high barrier against counterfeiting.


Benefits of Secure Windows

  • Can be quickly verified by users, and easy to authenticate

  • The production process is exclusive and not available in commercial print and paper technology

  • Paper- and foil-based visual effects in the applied strip also increase security

  • Attempts to counterfeit windows reprographically result in a black window
