What kinds of ink are there in screen printing?What are the characteristics?
Screen printing ink is a kind of printing ink, its variety is various, and the classification method is also various. But the main classification methods are as followsAccording to the characteristics of ink classification: can be divided into fluorescent ink, bright ink, fast fix ink, magnetic ink, conductive ink, aroma ink, UV drying ink, sublimation ink, transfer printing ink and so onAccording to the state of ink classification; colloidal ink, such as water-based ink, oily ink, resin ink, starch paste, etc. solid ink, such as electrostatic screen printing toner
The features of screen printing are summarized as follows:Screen printing can use a variety of types of ink, namely: oil, water, synthetic resin, emulsion type, powder and other types of inkThe layout is flexible. The screen printing is flexible and has a certain elasticity. It is not only suitable for printing on soft articles such as paper and cloth, but also for printing on hard objects, such as glass, ceramics, etc.Screen printing has little printing force, and it is suitable for printing on the breakable shopping because of the little pressure in printingThe ink layer is thick and strong covering powerLimit and area size restrictions and is not affected by the surface shape of the substrate. By the foregoing, screen printing can be printed on the plane, but also can be printed on the surface or sphere; it is not only suitable for small object and printing, but also suitable for printing on large objects. The printing mode has great flexibility and wide applicability.
According to the classification of printing materials:The paper with ink ink, water-based ink, high gloss ink, light ink, semi volatile drying inks, natural drying ink, ink, paint paper plastic synthetic paper ink and paper board box type printing ink.Fabric ink: water-based ink, oily ink, emulsion ink and so onWood ink: water ink, oily inkMetal ink: aluminum, iron, copper, stainless steel and other metal specific ink. Leather ink: printing leather special inkGlass ceramic ink: glass instruments, glass crafts, ceramic inkPlastic ink: polyvinyl chloride ink, styrene ink, polyethylene ink, acrylic ink and so onInks for printed circuit boards: electrically conductive inks, corrosion resistant inks, resistance to electroplating and fluorine and alkali resistance inks
