The thickness of the ink refers to the degree to which solid powdery substances such as pigments and fillers mixed in the connecting section are dispersed.

The thickness of the ink is also an important quality index, because it is not only related to the application performance of the ink (including tinting power, hue, stability, etc.), but also related to the rheological performance of the ink and economic benefits. If the ink is too thick, it will cause defects such as ink stacking and pasting, and the tinting power and hue of the ink will also become worse. If the ink is too thin, the fluidity will be great, and it will flow after printing. This flow will cause the dots to expand and affect Print quality. In addition, the thickness of the ink also affects its dispersibility. When the dispersibility of the ink is not ideal, its printing performance will not be satisfactory, as the surface of the printed matter is not smooth, smooth, and soft, and it will produce a "blocky" feel, which greatly reduces the printing effect.

In actual printing, you can choose different thickness inks according to specific requirements. When printing printed matter with thin screen lines and high precision, the fineness of the ink should be higher; when printing the prints or field prints that do not require high accuracy, the thickness of the ink can be appropriately reduced. Reduce costs and increase economic benefits.
