Back in the workshop, Vijay was inspecting the anti-counterfeiting measures for the printing of currency.
To combat counterfeiting, a combination of complex designs and special colours, created using multiple dyes, was employed to distinguish genuine notes from counterfeit ones. Security threads and holograms were also integrated into the currency. These holograms, printed on paper, offered an additional layer of protection, visible only under specific lighting conditions. Metallic threads were woven into the currency during manufacturing, further complicating counterfeiting attempts. Fortunately, advancements in machine tools enabled the mass production of these thin threads, heightening the complexity of counterfeiting.
