What is the advantage of water-based ink?

What is the advantage of water-based ink?Because of water as a carrier for dissolution, water-based ink has significant environmental safety features: safe, non-toxic and harmless, non-flammable and non-explosive, almost no volatile organic gas generation, the advantage of water-based ink mainly in the following three aspects.

1.The biggest advantage of water based ink is not pollute the environment

 VOC (Volatile Organic Gas) is recognized as one of the major sources of global air pollution today. Solvent-based inks emit large amounts of low-VOCs due to the water-based ink being dissolved in water. So whether in its production process, or when used in printing. Volatile organic gases (VOCs) are rarely emitted to the atmosphere. This is unmatched by solvent-based inks. Solvent ink in the production process, emitting a large number of low concentrations of VOC. According to estimates. General solvent-based ink manufacturing plant. If not fully enclosed production equipment, volatile organic solvents account for about 0.3% ~ 1% of ink production. For the treatment of low concentration of VOC, in addition to a handful of ink factory using such as activated carbon adsorption and other high-cost processing methods. Most are directly discharged into the atmosphere at high altitude. Not only that, in the printing process, the organic solvent in the solvent-based ink is almost completely dried and quickly volatilized out. In addition to the high concentration of VOC above the printing press is used such as catalytic combustion or microbial treatment process, the concentration of low concentrations of VOC in the air of the printing plant is often directly discharged into the atmosphere, if the solvent-based ink in the proportion of organic solvents 25% ~ 35% of the calculation, the amount of VOC directly into the atmosphere is quite alarming. The water-based ink just overcome this shortcoming. This unique feature of the air pollution-free environment is being more and more printing companies are optimistic about

2. The second advantage of water based inks is that they reduce residual toxic substances

Water-based ink completely solve the toxicity of solvent-based ink. Due to the absence of organic solvents, the residual toxic substances on the printed surface are greatly reduced. This feature. In the tobacco, alcohol, food, beverages, medicines, toys and other health conditions demanding packaging and printing products also reflects the good health and safety. Nowadays, human beings pay more and more attention to food safety. Has been concerned about the health and safety of food packaging. The packaging materials and packaging printing of harmful substances in the residual amount of strict requirements. The use of solvent-based ink printed matter to achieve food hygiene and safety requirements quite difficult. This is for printed matters that use water-based inks. It is a breeze.

3.The third advantage of water based ink is to reduce the cost of consumption

Due to the inherent properties of water-based ink & mdash; It can be deposited on a thinner ink film. Therefore relative to solvent-based inks. Its coating amount (amount of ink consumed per unit of printing area) is less. After testing. Compared with solvent-based inks. A coating amount of about 10% is reduced. In other words, print the same number and specifications of the print. Water-based inks consume about 10% less solvent-based inks. Not only that, due to the need for frequent printing plate cleaning. Therefore, the use of solvent-based ink printing. Need to use a lot of organic solvent cleaning fluid, and use water-based ink printing. The medium to be cleaned is mainly water. From the perspective of resource consumption, water-based ink is more economical and in line with the theme of a conservation-oriented society advocated by the world today.
