1. Precipitation of ink pigments. Before use, the ink in the ink tank should be evenly stirred. When printing, the ink in the ink tank should often be stirred to prevent the color of the printed matter from being different from the standard due to the precipitation of the ink pigment. An effective way is to keep the ink in the state of stirring and flowing under the operation of the ink pump through the fully enclosed scraper. 2. During storage and use, due to the volatilization of the stabilizer in the ink component, the pH value is reduced (tends to be weakly alkaline). In use, the stabilizer of water-based ink is volatile, so that the ink tends to be weakly alkaline, causing its surface tension to increase, but the adhesion to the surface of the printing plate decreases, affecting the transfer performance and drying speed (the more the ink tends to be alkaline, the more dry The speed is accelerated), which will cause the printing graphics and texts to be incomplete during the printing process, especially when printing the screen version, because the ink dries too fast, the printing dots are lost or the screen version is blocked. 3. Due to the volatilization of water in use of the ink, the viscosity of the ink increases and the flow performance decreases. The ink supply method of some printing equipment is a single blade system, which requires the ink to have a certain viscosity and fluidity, so that it is within a relatively suitable range. When the gap and fluidity of the ink in use exceed the requirements for printing, it will affect the transfer performance of the ink, and there will be "color difference" on the surface of the printed matter.
