U.V. Switch is a unique innovation that we have developed for threads and surface applied features. Threads, patches and stripes are some of the most easily recognised security features. There are relatively few paper mills that can incorporate them into the paper and for this reason they're usually reserved for high value documents such as passports or bank notes.
U.V. Switch thread provides an instantly recognisable and robust anti-counterfeiting feature. The combination of fluorescent coloured images, which can combine or 'switch' under transmitted and reflected U.V. light, makes this ideal for windowed or fully embedded thread.
Until now you've had a limited choice of embedded threads and the market has tended towards the use of more expensive windowed threads. U.V. colour switch thread is readily seen from both sides and although less expensive than it's counterpart, it retains a high degree of security and user appeal.prev: planchettes next: starlites
