The intaglio method is a printing technique used to create high-quality images on banknotes, stamps, and other important documents. It is commonly used for printing currency due to its ability to produce intricate designs and high levels of security features that make it difficult to counterfeit. In the intaglio printing process, the design to be printed is etched or engraved into a metal plate, usually made of steel or copper. The plate is then coated with ink, and the excess ink is wiped away, leaving only the ink in the engraved areas. The plate is then pressed onto the paper, transferring the ink and creating the final image. The intaglio printing process allows for very fine lines and details to be reproduced accurately, resulting in a high level of quality and security. Additionally, intaglio printing produces an embossed effect, where the ink is slightly raised above the surface of the paper, which can be felt when running your fingers over the note.
