Security threads - embedded authentication solutions with multi-level counterfeit protection
Security threads are a highly effective and good value long-lasting security feature. Widely recognized by the public, security threads are extremely complex to produce to ensure protection against counterfeiting. During cylinder-mould paper making, security threads are either fully embedded into a banknote or appear as evenly spaced window threads on its surface.
Security threads can be used in a wide range of applications and are versatile in design. Hologram and ColourShift design effects are both popular and eye-catching, providing quick and easy authentication for the public. Security threads incorporate multi-functionality including holograms, de-metallization, UV luminescence, and machine-readable properties, all within a thread typically up to 5mm wide.
Louisenthal has a long experience of producing security threads. As Louisenthal is also a producer of banknote substrates, all of our threads are optimized for embedding into currency paper.
