What is in currency ink?

Currency ink typically contains a combination of dyes, pigments, and special additives that give it unique properties. These inks often include security features such as ultraviolet (UV) reactive elements, magnetic materials, and color-shifting pigments to deter counterfeiting. Additionally, they may contain elements like carbon black for black ink or various organic compounds for vibrant colors, ensuring durability and visibility on banknotes. The specific formulation can vary between countries and denominations for added security.
