With the strengthening of environmental awareness, green printing is not a short fashion, but an inevitable trend of development. The so-called green printing refers to the printing to protect the environment consciousness, to strengthen the printing company attaches importance to the idea of environmental protection, and vigorously promote the conservation of resources and energy, the implementation of circular economy, adhere to Scientific Outlook on Development, to eliminate the harm due to environmental problems caused by the printing, and create a good living space for the purpose of human being. So how can we achieve green printing? This problem has been plagued by the majority of the printing business, and now we have explored through this has a lot of insights. We can improve the printing materials such as printing ink is the world recognized environment-friendly printing materials, because the water is a polar material, according to the characteristics of polar compounds with polar material compatibility, water-based ink does not contain or only a very small amount of organic solvent, therefore, the maximum water ink is the advantages of reduced the emission of VOC, so as to avoid the volatile organic pollution, improve the printing operation environment, beneficial to human health. In addition, it can also reduce the fire hazards caused by static and flammable solvents, reducing the surface of the printing ink residue odor. Secondly, the use of environmentally friendly technology for the treatment of waste gas, waste of waste generated in the printing process of special collection of, for which the price of paper and other items for recycling, on film, plastic film and other refractory environmentally hazardous substances, waste recycling by unified recycling processing resources or sanitary landfill. At present, because of technology and other factors, also had to use various printed materials with the pollution, such as oil, oily, oily ink coated on the other, harmful and toxic gases are produced in the process of using, can exhaust adsorption, recovery, catalytic combustion device for processing, reduce the concentration of harmful gases in the work environment, reduce the harm to the human body, but also reduce the pollution of harmful gas to the environment. The optimization design of the concept of green packaging design packaging design should follow the ecological, harmless, reduction, from material selection, structure and function, production process, packaging, storage, product use and waste treatment and other aspects of a comprehensive assessment of the use of resources, environmental impact and solutions.
