Background

Printing is a technique of transferring ink to the surface of a material such as paper, fabric, or leather by performing processes such as plate making, inking, and pressing on an original such as characters, pictures, or photographs, thereby mass-transferring the contents of the original. Printing in the simple sense is the process of transferring the graphic information on an original to a substrate using a printing plate or other means, and may also be understood as a reproduction process using an analog or digital image carrier to transfer a colorant/pigment (e.g. ink) to the substrate.

The components of the ink are complex, and the skinning phenomenon can easily occur in the printing process. The skinning phenomenon of the ink means that: the surface layer of the packaging printing ink is contacted with air in the printing process due to drying such as normal-temperature oxidation, permeation, volatilization, evaporation and the like, and the oxidation of vegetable oil or the volatilization of an organic solvent causes the gel formed by the polymerization and other actions of an ink system. This phenomenon causes much annoyance to printing companies and operators of printing presses. During the printing process, the ink needs to be continuously stirred to prevent the occurrence of the skinning phenomenon. The prior technical scheme is that ink is generally conveyed from an ink supply barrel to an ink tank through a booster pump, and then the ink flows back to the ink supply barrel through a pipe or a tank, so that the ink can circularly flow, and the ink is prevented from being crusted, but the ink is viscous liquid and has low fluidity in the ink tank.
