Maturation is done to speed up the curing of the glue between the materials. When printing, gravure printing is used, which means that the characters and patterns on the original are made into plates, ink is applied on the surface of the printing plate, and the image on the printing plate is transferred to the surface of the printed material by pressure. , the same print as the original is reproduced accurately and in large quantities. The cutting is also done by cutting the printed and composite materials into the specifications required by the customer.
