Imitation metal etching printing, also known as matte printing, is a new process that has only emerged in recent years. The surface of the printing product produced by this process can produce a uniform, such as mechanical sandblasting convex material, especially printed on metal cardboard can produce a special gloss effect of the metal after corrosion, greatly improved Product grade.
Imitation metal etching printing process is mainly using UV light curing special ink, using screen printing process to obtain the etching effect. The ink material is colorless or multi-color translucent. After printing on the metal cardboard, the high-gloss portion is covered so that a subtle contrast between the weak gloss effect formed at the ink and the bright gloss at the non-inking region is formed. At the same time, the feel of the printed product is matte, and the overall effect is very elegant if the metal is etched. It should be pointed out that the choice of printing paper bottom paper is very important. The metal glossiness and flatness of the bottom paper are good, and the surface effect of the printed product is better, and vice versa. Plate-making screens can generally use 180 mesh/inch (1 inch = 2.54 cm) and fine patterns can use 250 mesh/inch. When printing, the ink must maintain a certain degree of viscosity, not too thick, and cannot be mixed with other inks. The UV light curing device preferably has a light source power of about 10 kW. It is recommended to install 3kW 3pcs or 5kW 2pcs. The substrate should be cured within 3~5s in the light area. Therefore, the distance that the printed product passes should be considered. At the same time, it should also be equipped with cooling and cooling devices.
