Gravure ink as a dispersed phase of pigments and again the links as a continuous phase of a solid coarse dispersion system. Which give color to ink pigment, links, supply the necessary ink transfer and drying performance. Color performance, flow property, ink drying performance is the most basic and most important performance. Ink in addition to the main agent, there were various enhancers as additives, to improve the performance of the ink for printing eligibility and so on.
 
Resolution of gravure ink quality factors, there are two: (1) the choice of raw materials. Raw material is the basis of the ink components. The selection of raw materials, cooperate and quality of raw materials, is the basic factor resolution ink quality. (2) the combination of raw materials. Ink is a multiphase dispersed system. Ink in liquid medium material, the interaction between the liquid - liquid relations; Between the pigment particles interact with each other, that is, solid - solid relationship; Liquid medium material and pigment particles, the interaction between the solid - liquid. Among them, the pigment is also the final resolution between printing ink raw materials combined with how an important factor that effect the selection of pigment is equally important.
