U.V Switch™

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.
