Security Features
Louisenthal has developed a wealth of effective security features for banknotes. Combining counterfeit resilience with visual and aesthetic appeal, they are the result of sophisticated processes and precision engineering. And our secret ingredient: complete understanding of the entire cash cycle. After all, we’re a subsidiary of the high-tech security company Giesecke+Devrient. We help you analyse and define the circulation conditions of your notes and advise you on the best type for you. We work with you to determine the requirements you’ll need to meet for machine processing. Of course, our entire production processes are based on manageable sustainability aspects, which are outlined in our sustainability newspaper “Life of a banknote”.
Our holistic, integrated approach helps ensure that your security features stand the test of time. They span watermarks, secure windows and foil elements through to security threads, printed features and embedded covert security. Plus: Louisenthal’s security features can be used separately or synchronised so that they work together and communicate with each other. Our goal is to help you maximise security on every authentication level – public verification, cashiers, small POS devices and large processing systems. At the same time, we ensure that your banknotes are always extremely attractive and eye-catching. This combination offers you maximum flexibility in implementing the exact level of authentication you require.
Watermarks
Our three-dimensional, highlight and pixel watermarks can be used singly or combined – and we’re always working on new, advanced technologies that allow for a creative design. That results in higher protection and faster verification for everyone.
Security Threads
Our threads help the public to check their note is authentic. And security is not the only benefit: the gleaming threads are both attractive and eye-catching. They can also be equipped with functional properties to enable machine processing.
Foil Elements
Easy to recognize and available in different dynamic colours and effects, Louisenthal foils enable you to position striking designs across the banknote. They are based on exclusive and counterfeit-resilient origination technologies that bring your customer-specific designs to life.
Secure Windows
Louisenthal’s unique varifeye® windows are innovative security elements with surprising optically variable effects in reflection and transmission. They can be incorporated into a patch or a foil stripe and offer secure window effects as well as additional front-to-back verification.
Embedded Covert Security
Louisenthal’s innovative, covert security features can be integrated in security threads to boost a banknote’s functionality at different authentication levels.
Printed Security Features
Iridescent and colour-changing inks create alluring security effects, making them ideal for rapid authentication and very difficult to forge. Depending on the viewing angle, the printed elements are either visible, invisible or change colour when the note is tilted.
Unmatched counterfeit protection
To stay ahead of counterfeiters, we provide diverse and unmatched security features and cutting-edge technology. With our holistic feature strategy, we offer our customers the opportunity to provide their banknotes with a customised combination of optical and machine-readable security features.
