Watermark
Description
A watermark is an image in a banknote. It can be a figure, a pattern, or a denomination of the banknote. We can normally not see a watermark directly but have to use transmitted light through the paper. Watermark is a long-lasting tool for checking the authenticity of a banknote and its global recognition.
There are two processes of making a watermark: the Dandy Roll process and the Cylinder Mould process. The Dandy Roll process was created by John Marshall in 1826, the technique uses a wet dandy roll that rolls along a banknote for drawing a figure. Meanwhile, the Cylinder Mould process was created a little bit later in 1848, and it can create three dimensional hologram in order to increase the security of a banknote. This technique was also widely used before digital watermark became popular.
Since the making process is a very expensive and high-required technology, it is not easy to personally reproduce a watermark, hence this provides a good security for a banknote. Moreover, as it is embedded in a banknote, it is very permanent and long-lasting during the (economic) life of a banknote.
