Microprinting is a security feature used in various documents, such as banknotes, passports, and checks. It involves printing tiny text or patterns that are difficult to see with the naked eye but can be viewed clearly under magnification. This technique helps prevent counterfeiting and forgery by making it challenging for unauthorized individuals to replicate the printed material. The microprinted text often includes specific information, such as serial numbers or security messages, which can be verified by authorities. Because of its small size, microprinting is an effective way to add an extra layer of security without altering the overall design of the document.
