Screen printing refers to the use of silk screen as a plate base, and a screen printing plate with graphics and text is made by a photosensitive plate-making method. Screen printing consists of five elements, screen printing plate, squeegee, ink, printing table and substrate. Printing is carried out using the basic principle that the mesh of the screen printing plate can penetrate the ink, and the mesh of the non-graphic part cannot penetrate the ink. When printing, pour ink at one end of the screen printing plate, apply a certain pressure to the ink part on the screen printing plate with a scraper, and at the same time move towards the other end of the screen printing plate at a constant speed. Part of the mesh is extruded onto the substrate.

Cosmetics and cosmetics packaging materials bronzing process

The process of bronzing includes:

Hot stamping preparation → plate loading → pad plate → determination of hot stamping process parameters → trial hot stamping → sample signature → formal hot stamping.

Hot stamping is a special printing process without ink. The so-called hot stamping refers to the process of hot stamping anodized aluminum foil to the surface of the substrate under a certain temperature and pressure.

The pictures and texts of the packaging anti-counterfeiting anodized aluminum hot stamping show a strong metallic luster, the colors are bright and dazzling, and never fade.
