Advantages of water-based inks in printing costs

Plastic water-based ink is composed of water-based resin, additives, pigments, water and other raw materials. When selecting materials, all need to meet the requirements of environmental protection. In the production process, pure water is used instead of organic solvents. Water-based ink is non-flammable, non-explosive, odorless and non-toxic. It is the world's most environmentally friendly printing ink.

Water-based ink environmental advantages

Plastic water-based inks use water as a solvent, and there is no organic solvent (VOC) volatilization and no odor during the printing process. There is no pollution or damage to the environment or to the printing operator's body. Water-based ink products will not burn themselves, and will not cause fire due to static electricity and short-circuit of wires, etc. Water-based inks will be used for printing, and the printed products will not have any residual solvent. It meets the environmental protection requirements for food packaging and other packaging in any countries and regions in the world. .

Advantages of water-based inks in printing costs

With water-based ink printing, first it does not need to be diluted with any organic solvent, only with clear water. The printing industry often says "how much solvent can be added", such as adding 30% to 50% of the solvent in the ink, and mistakenly believe that the more solvent the better, the lower the cost. In actuality, the added 30%-50% of the solvent is added during the entire printing process, which is due to the volatilization of the solvent causing the viscosity of the ink to change. The quicker the printing speed is, the faster the volatility of the formulated diluent is, and the more times the solvent is added, which means that the printing cost is constantly increased. Therefore, it is not until the 10KG ink is added with 5 KG solvent that printing starts. According to industry standards, inks have high color concentrations and low viscosity (except for screens, etc.).

This relates to the raw materials selected by the ink manufacturer, such as the molecular weight of the resin, the formulation, and the production process. The amount of solvent added in the printing process is different from the closed printing room, and the rest will be changed due to factors such as temperature, wind force, etc. The addition of thinner to the ink is only to reduce the viscosity of the ink, making it suitable for printing, such as excessive When added, the color density of the ink will be reduced, and the amount of the binder will be reduced at the same time so that no good product can be printed. Therefore, water-based inks only add pure water, and they are added at one time (prepress). In the printing process, it will not cause the color change due to the change of viscosity, and it will not be like the ink, due to the waste generated when the diluent is added during the printing process, which greatly improves the pass rate of the printing product and saves The cost of the solvent reduces the appearance of waste, which is one of the cost advantages of waterborne inks.
