Multiply printing refers to the process of producing multiple copies of a document or image using a printing press or digital printer. This method allows for efficient and cost-effective reproduction of materials, making it a popular choice for businesses, schools, and individuals. It involves creating a master copy and then using it to create identical copies through a series of mechanical or digital steps. Multiply printing has revolutionized the way information is disseminated and has made it possible to distribute large quantities of materials quickly and accurately.
