Banknote Production and Security Features​

​"Banknotes are legal tender for all debts, public and private" Therefore, in order to maintain its reliability as medium of exchange, "banknotes" are to be produced with particularly anti-counterfeit features. Banknote patterns are specially designed with distinctive characteristics in the hope that people can easily recognize.

Three easy-to-follow methods to distinguish genuine national banknotes from counterfeit ones include FEEL, LOOK and TILT.

FEEL​

1. The Banknote Paper  

The Banknote Paper is made of special paper manufactured from cotton fiber which makes it tougher and more durable. The thickness of each banknote denomination is differentiated allowing the distinctively tactile feel to the touch.​

2. Raised Print

This happens when the specially designed printing press comes into contact with the banknote paper and the ink is forcibly drawn from the plate onto the paper under very high pressure. This process, called Intaglio, results in raised print and produces high quality clearly defined images. Intaglio printing is suitable for printing some areas requiring raised print such as the portrait of His Majesty the King or the numbers identifying value.

Raised prints can be easily sensed in the area of the royal emblem, the word “รัฐบาลไทย” (Thai Government), denomination in words and numerals .
