Establishing standards is a double-edged sword to promote China's green printing

1) The basic principles and framework for my country to formulate environmental protection standards for printing　　The implementation of green printing in our country is still a new thing. We mainly draw on the experience and practices of developed countries and combine our country’s actual conditions to formulate standards, monitoring methods, and some related measures that meet our national conditions. The basic principle is: adhere to the scientific development concept, protect the rights and interests of consumers, in line with the people-oriented tenet, while drawing on and absorbing foreign standards, pay attention to the actual situation of our country; gradually improve the environmental protection standards of various printed materials, and steadily promote the development of logo products. The scope of application is to promote the structural adjustment and technological upgrading of the printing industry, reaching and approaching the level of developed countries in a relatively short period of time.　　 Standard Framework: Taking the environmental protection standards of printed products as the starting point and end point. Formulate environmental protection standards for printed matter, including requirements for heavy metal content, materials, auxiliary materials, and processing techniques in printed products, as well as pre-press, in-print, post-press, material treatment, waste water (including various chemical syrups, car wash water), waste (cleaning cars) Cloth, PS version), exhaust gas emission, finished product recycling, etc. Specify the qualifications and inspection methods of inspection agencies.　　The formulation and implementation of standards are carried out under the leadership of the government, which means that the government issues standards and specific implementation methods. The Ministry of Environmental Protection and the General Administration of Press and Publication jointly signed a green printing strategic cooperation agreement, led by the China Printing Technology Association, specially established the "Green Printing Promotion Office of China Printing Industry" (referred to as "Green Office"), responsible for related research and standard drafting , Publicity and promotion, and actively participate in the formulation and promotion of green printing standards by the Ministry of Environmental Protection.　　 (2) The steps and process of formulating technical standards for printed environmental labeling products.　　 The standard kick-off meeting was held from June to July 2009 to set up a standard preparation team to determine the direction, scope of application and reference basis for standard formulation.　　 From July 2009 to March 2010, the compilation team organized experts to conduct on-site investigations in Beijing, Shanghai, Guangzhou, and Jinan, and finally formed a draft of the standard.　　 In February 2010, the Ministry of Environmental Protection and the General Administration of Press and Publication held a meeting in Beijing on green printing and printing environmental label standards, and discussed the significance of the implementation of the standards and the impact on society.　　 The establishment group and expert group meetings were held in March 2010. The draft standard was approved in principle and suggestions for revision were made. From May 12 to 14, 2010, the Environmental Certification Center of the Ministry of Environmental Protection and the China Printing Association organized industry experts and Heshan Artos, China Business (Hong Kong) Company, Junsi Group, Apex Group, Tianjin Dongyang, Fuji Star, Jindong Paper, Wende Xiangchuan, Heidelberg [Product News Space], Shanghai Meiji, China Banknote Credit Card, Shanghai Yanyin, Changde Jinpeng, Shanghai Zijiang Color Printing, Zhejiang Dongxiang New Oriental, Jiangsu Caihua, Wuhan Red Golden Dragon, Shenzhen Jinjia , Guanxingyu Banknote Special Anti-counterfeiting, Dongtian Transfer, Xinjintuo Exhibition, Zhuhai Letong, Zhongshan Songde, Yuncheng Plate Making, Shaanxi Beiren, Guangzhou Tongze, UPM, Donggang Security Printing, Xi'an Xizheng, Shanghai 34 participating companies including Yinuoer, Shanghai Sun Machinery, Beijing Zhongyin Zhoujin Technology, Guangdong Guanhao, Sichuan Xincai, Zhejiang Mozhihua, Yichang Dachang, and Fujian Hongbo Co-edited Enterprise Technical Experts to carry out the standard sentence by sentence Confirmation of the word revision, and submit a draft standard for comments, and submit it to the Ministry of Environmental Protection. After full re-investigation and repeated revisions from June to August, the draft for comments was widely solicited by the Ministry of Environmental Protection in September 2010. At the same time, the relevant participating enterprises will be technically verified in mid-to-late September. It is expected that the draft will be approved by the end of the year. Promulgated and implemented by the Ministry of Environmental Protection.　　 (3) The standard is mainly aimed at and the problems to be solved.  1. Solvent contamination problem.　　Solvent-based inks need to add a large amount of solvents when they are on the machine. Domestic printing companies generally do not consider the recovery of solvents when printing, which causes the pollution of large organic volatiles; 2. Environmental issues of ink. The environmental problems of inks have gradually been paid attention to by everyone. Due to the lack of effective environmental protection laws and regulations in China, there is no basis for discrimination when choosing ink products, resulting in harmful residues in printed materials; 3. The choice of printing material. Except for a small part of the printing materials provided by Party A, most of the materials are prepared by the printing company. The choice of printing materials is basically based on price as the main criterion, without considering environmental issues, causing environmental hazards to printed materials.　　 Therefore, it is very necessary to formulate environmental labeling standards in the printing industry. Improve the certification methods and procedures for green printing companies and printed products, improve the functions of certification bodies, and gradually expand the scale of green printing companies and the proportion of green printing processes. Formulate policies and measures to encourage printing companies to develop a low-carbon economy, strengthen environmental protection measures, and develop green printing. Organize the "Green and Environmental Printing System Construction Project", and drive the industry's green, environmental protection and low-carbon development with green environmental protection projects. With primary and secondary school textbooks, government procurement products and food and drug packaging [Wikipedia] as the focus, we actively coordinate environmental protection, education and other relevant administrative departments to carry out multi-level and multi-faceted cooperation, and vigorously promote the development of green printing in China. Promote the development of packaging and decoration printing in the direction of reduction, reuse, recycling and degradability (3R+1D). Actively promote the application of flexographic green and environmentally friendly printing, and promote the research and development of low-energy processing, waste liquid treatment equipment, and green printing equipment and materials such as water-based inks and water-based coatings to provide support for sustainable development. Continue to improve the production capacity elimination and exit mechanism after the printing area, clarify the elimination criteria, quantify the elimination indicators, increase the elimination efforts, and eliminate a batch of production capacity with serious pollution, backward technology and equipment, low production efficiency, and high resource and energy consumption as soon as possible. Significance of standard formulation and implementation After the three standards are promulgated, they will have a significant impact on my country’s printing industry, which can greatly help and promote my country’s printing industry to achieve the goals of energy conservation and emission reduction and the development of a low-carbon economy, and to improve and enhance my country Environmental protection level of the printing industry.　　Because many printing companies continue to use traditional printing technology, the printing industry still has some environmental problems in some production links, such as the volatilization of solvents that are toxic and harmful to humans and cause air pollution, damage to water quality, and discharge of waste water that pollutes soil. The promotion of environmental labeling standards can play a major role in the following aspects:  reduce the use of highly polluting inks.　　Reduce the use of fountain solution containing isopropanol.　　 dampening solution is a necessary condition to ensure that the blank part of the printing plate forms a hydrophilic salt layer. At present, the isopropanol dampening system is used on the offset printing machine. Since the alcohol vapor produced by the volatilization of isopropanol is toxic and will have harmful effects on human health, many developed countries stipulate that the threshold of isopropanol in the workplace is only 200-400ml/m3. Through the implementation of this standard, the use of isopropanol can be reduced, and it will eventually be completely replaced in the printing industry.　　 Promote the application of CTP system.　　 At present, most of the printing industry in our country still uses the phototypesetting machine to produce a PS plate for printing on the machine. The film is a silver salt photosensitive material, which contains silver ions, and the waste fixing solution after fixing also contains a large amount of silver ions. These substances directly enter the environment and cause harm to the water environment, while the development, fixing and washing waste liquid contains a large amount of organic matter , Belongs to hazardous waste, the country prohibits direct discharge, but there are certain shortcomings in the environmental management of domestic enterprises, and some enterprises do not pay enough attention to them, and gradually strengthen environmental management through environmental signs to achieve corporate environmental progress.　　 Through the formulation of environmental label printing standards, in the four life cycle stages of design, manufacture, use, and disposal, not only the process control of design and production is rushed, but also clear quantitative requirements are put forward for the use and disposal of printed products. Improve the technological level of my country’s printing industry, promote the structural adjustment, transformation and upgrading of my country’s printing industry, grow bigger and stronger into an excellent large and medium-sized environmentally friendly printing enterprise, eliminate serious polluting "small workshop" type low-quality enterprises, and promote my country The realization of the goal of transforming from a “printing power” to a “printing power”. Green printing has become an important starting point for the government authorities to adjust the industrial structure. Some printing products that are directly related to the health of the people should be assigned to enterprises that meet environmental protection standards for production by administrative means, so that outstanding enterprises can quickly become stronger and have certain conditions. For those companies that do not know how to make progress, they will be eliminated through continuous expansion of green printing varieties, and finally the industrial structure will be optimized. Recently, the General Administration of Press and Publication has organized People's Education Press, People's Music Press, People's Fine Arts Press, Beijing Normal University Press, Education Science Press, Shanghai Education Press, Shanghai Foreign Language Education Press, and Beijing Meitong Printing Co., Ltd. , People's Education Publishing House, Beijing Jingshi Printing Co., Ltd., Sichuan Xinhua Printing Factory, Sichuan Xinhua Color Printing Co., Ltd., Sichuan Jinzhu Printing Co., Ltd., Sichuan Lianxiang Printing Co., Ltd., Chengdu High-tech Zone Longjiang Color Printing Plant, Shandong Linyi Xinhua Printing and Logistics Group, Shanghai Zhonghua Printing Co., Ltd., Commercial Press Shanghai Printing Plant and other units have launched a pilot program for green printing of textbooks in the fall of 2010. The entry point is the environmental protection requirements for the printing of textbooks in primary and secondary schools, involving 7 publications. The society’s 100 textbooks and more than 14 million copies have been printed, covering 20 provinces (regions and cities). After the environmental protection standards for printing are officially promulgated, some printed products, such as textbooks for primary and secondary schools, government-purchased printed matter, and children’s books, will be strictly enforced; the next step will be extended to beverage packaging, puffed food packaging, pharmaceutical packaging, health care product packaging, etc. Cosmetic packaging and other printed matter, and gradually expand the variety category, and finally achieve full coverage of green printing.
