After the ink is stored for a period of time, the upper part of the ink appears thin in the container, the viscosity is small, and the color and concentration are relatively poor; The lower part is thick, the viscosity is large, and the color and concentration are also relatively good.
Intaglio printing inks are thin and have a small viscosity, because the pigment is poorly dispersed in the connecting material; Excessive density of pigments or fillers; It is easy to precipitate after long-term storage.

Even after fully shaken, without affecting the use of the conditions, this state of the ink will give customers a bad impression, while increasing the burden of workers.
