Zero pollution, pure water based ink has successfully developed, will be put into operation by the end of 2014. At the appointed time, the pollution caused by the ink on the packaging of milk, cigarette paper, medicine and so on will be greatly reduced. 

Ink is the basic material of printing, but also the key to the implementation of green printing. Beijing Institute of printing printing and packaging engineering college dean weixianfu told reporters a few days ago, "gravure printing technique is currently used in most of the domestic printing, gravure printing solvent based inks due to the presence of heavy metals and volatile organic solvents (VOC), for food, medicines, children's toys, packaging of goods caused by pollution and endanger the health of users. 

However, the successful development of the Beijing Institute of Graphic Communication, "pure water" ink to solve this problem. Wei Xianfu said, "pure water" ink because of no volatile organic solvents, that is, VOC content is zero, the proportion of heavy metals also greatly reduced, basically achieved zero pollution". The technology is expected to be put into operation by the end of 2014, in 2015, the estimated annual output value of up to. 

Application of low pollution or even "zero pollution" ink, China is a key step in the implementation of green printing. Green printing refers to the use of environmentally friendly materials and processes, printing process, pollution, low energy consumption, waste products easy to recycle, the impact on the ecological environment of small print. 

Professor of mechanical and electrical engineering, Beijing Institute of Graphic Communication professor Wang Yiming introduction, "green materials" is one of the most direct application of green printing. Last year a total of 2 million copies of autumn of middle and primary school textbooks using green printing, accounted for 29% of the proportion of total printed materials to ensure at least one person a "green materials; Beijing green materials on a higher proportion of about 42.55%. 

Government released the 2012 implementation green pressworks achievement report "shows that since 2010, China's implementation of green printing. About 1.5% of annual emissions of volatile organic compounds, the energy consumption and material loss and cost per year reduction of about 5 billion yuan. State Press and Publication Administration of radio, the Ministry of education, the Ministry of environmental protection has jointly issued a notice: 2015 years ago, the country all primary and secondary school textbooks will be implemented green printing, and stamped on behalf of the green status of the ten ring seal. 

At present, there are more than 300 enterprises in the country to obtain green printing certification. The only print publications are being built in Beijing Institute of printing green quality inspection center, all printed materials, and paper can be here for testing to see whether the target is expected by the end of this year will be officially put into use.
