KURZ opens a window onto the banknote sector

KURZ is a pioneer in the use of smart windows as key security elements for banknotes.

KURZ is a pioneer in the use of smart windows as key security elements for banknotes. The latest generation of banknotes has raised the bar for our technologies.

The demands made on providers like KURZ are stringent and constantly evolving. Security elements must protect currency from sophisticated counterfeiting attempts, and at the same time harmoniously fit into banknote design. They must also be attractive and conspicuous enough to be easily checked for authenticity, and to be used as a means of payment.

As far back as 1994, KURZ began researching technology for smart windows in cooperation with the Deutsche Bundesbank. The original idea of punching out an opening as a window in a paper substrate to insert a security feature that appears when illuminated with light was successfully realized in the early 2000s. KINEGRAM REVIEW® foil strip technology has now been utilized for the portrait of the Goddess of Europe in the second euro banknote series.

Our unique KINEGRAM REVIEW® technology allows for different effects on the front and back of the foil, depending on the angle which the banknote is viewed from. A portrait, for instance, thus becomes visible on the front side of the smart window, while the monetary value appears several times on the back.


Our solutions for even greater counterfeiting protection

KURZ's innovative response to the ever more challenging demands made by central banks around the world today is to focus on versatile application and metallization methods such as KINEGRAM® APL (Applied Patch Label) and KINEGRAM ZERO.ZERO®.

In 2018 KURZ introduced the revolutionary KINEGRAM® APL technology for paper and composite substrates. This, for the first time, enabled production of bank notes with a foil patch in the smart window instead of a strip. The patch can now be applied directly at the banknote printing house, instead of only during the paper manufacturing process as before. Moreover, the opening for the smart window can be punched in any geometric shape.


KINEGRAM ZERO.ZERO® allows for filigree lines down to 40 μm in a single design, and for precise coordination of optical effects and metallization. This foil technology is particularly suited to projects requiring seamless integration into the overall banknote design.


Did you know…

  • ...that Foil-Over-Window technology was used on the 19-złoty bank note to commemorate the 100th anniversary of the founding of the Polish Security Printing Works (PWPW) in 1920? Manufactured with the new metallization technology KINEGRAM® High Definition Metallization (HDM), the banknote boasts remarkably precise metallic shapes and an impressive grayscale picture. 


  • ...that the Swiss banknote printer Orell Füssli introduced an unusually beautiful corporate banknote in three different versions for the 500-year anniversary of its founding? One of them bears a KINEGRAM® APL on the front side with a futuristic-looking snail emblazoned on the back with KINEGRAM REVIEW®.



  • ...that the Hungarian bank-note printer HBPC has designed and produced two sample banknotes to commemorate scientist Herman Ottó and his passion for birds, insects, and spiders? (Design by GYÖRGY PÁLINKÁS)

    Using KINEGRAM® APL and KINEGRAM COLORS®, a beautiful butterfly was applied to a smart window in a banknote, with the front showing off different colors. The other banknote shows a realistic illustration of a spider using KINEGRAM® APL, with demetallization performed by KINEGRAM ZERO.ZERO®.
