What are the characteristics of water-based ink environmental protection safety?
Water-based ink is dissolved water as the carrier, so the water-based ink has a safe, non-toxic harmless, non-combustible, almost no environmental safety characteristics of volatile organic gases, it mainly displays in the following two aspects.

1. Do not pollute the environment
VOC (volatile organic gas) is recognized as the world one of the main sources of air pollution, solvent-based inks will emit a lot of low concentration VOC, because of the water-based ink dissolved water as carrier. So it is almost impossible to release volatile organic gases (VOC) into the atmosphere, whether it is in its production process or when it is used for printing. This is incomparable with solvent - based ink. Solvent - based ink in the process of production, emitting a large amount of low - concentration VOC. According to the estimation, the volatile loss of organic solvents accounts for 0.3% ~ 1% of the ink production if the general solvent ink manufacturing plant adopts the production equipment that is not completely closed. In addition to the treatment of low concentration VOC, in addition to a few ink factories, such as activated carbon adsorption and other high cost processing methods. Most of them go straight into the atmosphere. Not only that, in the printing process, solvent - based ink organic solvents are almost completely dry and volatile. In addition to the printing press at the top of the high concentration of VOC used as catalytic combustion or microbial treatment technology, diffuse in the printing workshop low VOC concentration in the air is often directly discharged into the atmosphere, if according to the proportion of organic solvent in solvent ink is 25% ~ 35%, the number of VOC directly discharged into the atmosphere environment is quite amazing. And water - based ink just overcomes this shortcoming. This unique characteristic of air pollution is being favored by more and more printing enterprises.
Reduce residual pests
Ensure food hygiene and safety. Water-based ink completely solves the toxicity of solvent - based ink. The absence of organic solvents has greatly reduced the amount of toxic substances remaining on the surface of printed matter. This characteristic is more reflected in the strict packaging and printing products of tobacco, alcohol, food, beverage, medicine and children's toys. Nowadays, as people pay more and more attention to food safety, the hygienic safety of food packaging has been concerned, and the residual amount of harmful substances in packaging materials and packaging is also strict. The use of solvent - based printing ink to achieve food hygiene safety requirements is very difficult, and this for the use of water-based ink printing. It's a breeze.
