Several common processes are as follows:
Hot stamping:
The scientific name is anodized hot stamping. With the help of certain pressure and temperature, the printed matter and hot stamping foil are pressed against each other in a short time by using the template installed on the hot stamping machine, and the metal foil or pigment foil is transferred to the surface of the printed matter according to the pattern of the hot stamping template. At present, the widely used three-dimensional hot stamping technology makes the packaging of goods look high-grade, exquisite, gorgeous and full of personality. Printing bronzing technology is mainly used in greeting cards, bookmarks, trademarks, tobacco and alcohol packaging and various high-end packaging boxes.
Concave and convex:
Under a certain pressure, the printed substrate is plastically deformed, so that the printed appearance is artistically processed. Various relief figures and patterns present patterns with different shades, which have obvious relief feeling and enhance the three-dimensional sense and artistic appeal of printed matter. The concave-convex technology of Yunnan printing plant is mainly used for album covers, greeting cards and packaging boxes.
Braille:
When printing, when the ink is not dry, the lettering powder adheres, and after high-temperature melting and drying, the appearance of words or patterns forms a gelatinous substance, and the texture is embossed, forming a strong three-dimensional sense. Lettering and bump are easily confused by UV, and are generally used for lettering business cards. Other similar processes such as full-page and local UV, foaming, frosting, colorful, ice flowers, crystal lettering, etc.
Die cutting:
Commonly known as beer shape, the die-cutting technology of printing house is suitable for finishing all kinds of printed matter. Die-cutting quality directly affects the market image of the whole product. Mastering die-cutting indentation technology can effectively enhance the competitiveness of printing enterprises.
