Background

Ink is an important material for printing packaging materials, which presents patterns and characters on a printing material by printing, and includes a main component and an auxiliary component, which are uniformly mixed and repeatedly rolled to form a viscous colloidal fluid. Is prepared from pigment, binder and assistant. It is used for printing books, periodicals, package decoration, building decoration, etc. As social demands increase, ink varieties and yields also expand and grow accordingly. With the steady development of offset printing market in China, offset printing ink is rapidly developed, and the quality level of the offset printing ink is basically close to or reaches the international advanced level. According to incomplete statistics, the proportion of offset printing ink in the ink market of China is increased to 50% -60%, and still occupies the dominant position, and the proportion does not change greatly in a long period of time in the future.
