Ultraviolet lamps are used to detect forged banknotes by highlighting security features that are only visible under ultraviolet light. These features can include fluorescent inks and fibers that are embedded in the genuine banknotes but absent in counterfeit ones. By shining ultraviolet light onto the banknote, these features become visible and aid in distinguishing between genuine and fake currency.

The inks used in the printing of banknotes are specially formulated to include security features that prevent counterfeiting. These inks often contain unique pigments, color-shifting elements, and fluorescent properties that are difficult to replicate.

This combination of features helps maintain the integrity and trust in the banknote system.
