The Czech National Bank has upgraded its 100 and 200 koruna banknotes, including a colour-shifting security thread featuring Louisenthal’s Pole® anti-counterfeit feature.
The design of the new 100 and 200 koruna banknotes are based on the previous versions first issued in 1993. However, improved security features have been included to enhance each notes’ security and protect them against counterfeiting.
The key change includes a new 3mm wide windowed colour-changing thread, turning from orange to green when the banknote is tilted. The thread features Pole®, a covert security feature by Louisenthal, which is visible with a special polarised filter.
The thread also contains microtext of “CNB” plus the note’s denomination.
Other changes include an update to the watermark which consists of a portrait of Charles IV but now includes the denomination of 100 or 200 as well as a royal orb. The notes also include Omron anti-copy yellow circles, an offset pattern which, when detected by a digital imaging device such as a photocopier, causes the scanning function to cease.
The 100 koruna banknote was previously upgraded in 1995 and 1997, whilst the 200 koruna banknote was previously upgraded in 1996 and 1998. Both the upgraded versions of each banknote will continue to remain legal tender.
