Security printing refers to the specialized process of printing documents and items that require protection against forgery, counterfeiting, or unauthorized reproduction. This technique is commonly used for items like banknotes, passports, and identification cards. Security printing employs advanced technologies and materials, such as watermarks, holograms, and microprinting, to create unique features that are difficult to replicate. The primary goal of security printing is to ensure the authenticity and integrity of important documents. By incorporating various security elements, such as UV inks and optically variable devices, security printing helps to deter fraud and maintain trust in official documents and currency.
