UV: Wrap a layer of varnish (bright, matte, etc.) on a picture you want to print, mainly to increase the brightness and artistic effect of the product, protect the surface of the product. It has high hardness, corrosion resistance and friction resistance, and is not easy to scratch. Some laminated products are now UV coated, which can meet the environmental requirements, but UV products are not easy to bond, and some can only be solved by local UV or polishing.
Stamping: It refers to heating the embossed version made of the desired gilding or silver stamping pattern, and then placing aluminum foil paper of the desired color on the printed matter. After pressing, the aluminum foil is attached to the printed matter. There are many kinds of bronzing paper materials, including gold, silver, laser gold, laser silver, black, red, green, etc. This process can make the pattern on the surface of the printed matter clear, beautiful and dazzling, and the product itself is also wear-resistant.
Concave and convex embossing: the use of concave and convex molds, under a certain pressure, makes the printed substrate plastic deformation, thus performing artistic processing on the printed surface. Various embossed embossed figures and patterns show different patterns in depth, with a distinct sense of relief, enhancing the stereoscopic sense and artistic appeal of the printed products.
