Advantages and precautions of water-based ink in plastic printing

plastic water-based ink is composed of water-based resin, additives, pigments, water and other raw materials. When selecting materials, it is necessary to meet the requirements of environmental protection, and use purified water instead of organic solvents in the production process. Water based ink is non combustible, non explosive, tasteless and non-toxic. It is the most environmentally friendly printing ink in the world at present

environmental protection advantages of water-based inks

plastic water-based inks have no organic solvent (VOC) volatilization during the printing process due to water as a solvent, which is also good for avoiding metal fatigue and has no smell. There is no pollution and damage to the environment and the body of the printing operators who will have some small problems. The water-based ink product will not burn itself, nor will it cause fire due to static electricity, short circuit of wires and other reasons. When printed with water-based ink, the printed matter will not have any solvent residue, which meets the environmental protection requirements of food packaging and other packaging in any country and region in the world

advantages of water-based ink in printing cost

using water-based ink for printing, first of all, it does not need to be diluted with any organic solvent, and only water can be used. The printing industry often says how much solvent can be added, such as adding 30% - 50% solvent to the ink, and mistakenly believes that the more solvent is added, the better, and the lower the cost. In fact, 30% - 50% of the added solvent is added in the whole printing process, which is due to the change of ink viscosity caused by the volatilization of the solvent. The faster the printing speed is, the faster the volatility of the diluent to be prepared will be, and the more times the solvent will be added, which means that the printing cost will continue to increase. Therefore, it is not the 10kg ink that starts printing after adding 5kg solvent. According to the standards of the ink industry, the ink with high color concentration and low viscosity (except silk, etc.) is a good ink

this is related to the raw materials selected by the ink manufacturer, such as the molecular weight of the resin, formula, production process, etc. In addition to the closed printing workshop, the amount of solvent added in the printing process will change due to factors such as temperature and wind to enhance the comprehensive development of children. The addition of diluent in the ink is only used to reduce the viscosity of the ink and make it suitable for printing. If it is added excessively, the color concentration of the ink will be reduced, and the amount of connecting material will be reduced at the same time, so that good products cannot be printed. Therefore, only pure water is added to water-based ink, and it is added at one time (prepress). In the printing process, it will not cause color changes due to the change of viscosity, and it will not be like the waste products generated when diluents are added during printing, which greatly improves the qualification rate of printing products, saves the cost of solvents, and reduces the appearance of waste products. This is one of the cost advantages of water-based inks
