Problems solved by technology

[0002] Neutral ink is mainly composed of three main components: dye paste, solvent, and additives. It is generally used in office book writing, printing and other fields. There are many problems in the use of existing inks, and inks are usually due to the configuration materials. Determine the quality of the ink. When the existing ink is in use, some ink needs to be oxidized with air for a long time to show the color when it is printed or written on paper. It is extremely inconvenient for some workers, and the ink Generally, the concentration of the ink will be uneven, which will make the color of the ink uneven after use, which will affect the quality of printing. In the process, it seeps into areas that should not be reached, resulting in waste of paper, waste of resources and pollution of the environment, and different materials need to be replaced with different inks for printing, which is troublesome
