However, when performing vacuum sealed stirring, the solvent in the water-based ink is not added completely at one time. Furthermore, during the stirring process, some additives need to be added according to the process requirements. At this time, if the sealing cover is opened directly, the vacuum environment in the stirring tank will be destroyed, which will have a certain adverse effect on the ink. Utility Model Content
