One type of ink can be named differently according to different classifications, but common classification methods include: 1. According to the type of solvent in the ink, it can be divided into: water-based ink, solvent-based ink, UV-curable ink. 2. According to the classification of substrate materials, it can be divided into: paper ink, fabric ink, plastic ink, metal, glass, ceramic ink, leather ink, wood ink, circuit board printing ink. 3. According to the characteristics of the ink, it can be divided into: fluorescent ink, metallic ink, magnetic ink, conductive ink, gloss ink, matte ink, transfer ink, etc. 4. According to the drying method, it can be divided into: volatile drying ink, oxidative polymerization ink, two-component reaction ink, heat-curing ink, light-curing ink. Second, the function of ink The main function of screen printing ink is to form a graphic composed of printing material on the surface of the substrate through the screen printing process, which has strong adhesion, corrosion resistance, and decorative appearance after drying. Therefore, ink is not composed of a single variety or a single component, it is a mixture of several ingredients. Chapter Two: .
