Printing and environmental protection are important topics for the sustainable development of the global printing industry

Today's world is full of green prints, not only embodies the printing elements that make humans more civilized, more progressive, more harmonious life, but also a vivid interpretation of the indissoluble bound of human life from death and printing. The printing industry is also spreading the human knowledge civilization, improving the quality of people's lives, promoting the development of industrial technology, and building a modern cultural industry. In the view of environmental protection, the author thinks that the development direction of China's printing industry can be summarized as follows.

First, relying on international standards to lead the market in the beginning of the new century, environmental protection has become a global hot spot. In the field of printing industry, the rise of IS014001 international environmental management system, the launch of the national environmental protection printing standard/printing environment marking technology establishment in 2009, the legal level requirements of the “Food Safety Law” for packaging and printing, and even the Shanghai Municipal Science and Technology Commission, Shanghai The “2009 Shanghai International Printing Week” co-sponsored by the Municipal Economic and Information Committee and the Shanghai Municipal Press and Publication Bureau “Expanding, Digital, Technology, Environmental Protection, and Creativity” to interpret the theme of “The future of the printing market” all show green Printing and environmental protection packaging have become the trend of the printing industry. In the market environment where print buyers are increasingly concerned about the use of environmental public goods for production, printing companies need to rely on international standards to actively adopt and adopt new technologies in order to win in competition, gain greater market share, and generate more profitable product profits. New technologies, especially environmentally friendly materials and inks, can truly meet the goals of the market and realize the users' goals of “safety, hygiene, and environmental protection” before they can truly rely on energy efficiency, emissions reduction, air pollution prevention, and water pollution prevention. Noise pollution will enable printing companies to go ahead of market demand and lead the development of the green printing market.

From the point of view of advanced printing companies that are at the forefront of environmental protection in China, the successful development and market expansion of these companies is the first to predict and understand the potential demand of international printing buyers for the environmental protection of printed products, and to establish prevention standards for environmental protection of various developed countries. To establish exclusive measures for technical barriers and trade barriers, and to respond to all aspects of product planning, process design, material screening, and environmental protection product description, so as to obtain initiative in the international and domestic markets, high value-added product returns, and Different from the core competitiveness of similar companies, it also began to lead the development direction of the printing product market and form a sustainable development trend.

II. Continuing technological innovation and increasing environmental protection value Under the background that global environmental protection concepts are increasingly deepening into people's hearts and integrated into the public's trip, the printing industry driven by typical market demand and technological development only has insight into the specific needs of consumers for green products. In line with the trend of environmentally-friendly printing products, advanced environmental protection printing equipment and materials can be used to achieve continuous technological innovation in accordance with the goal of environmental protection printing in the accumulated technology system, and to enhance the environmental value of printed products for the sustainable printing industry. Development creates conditions.

The continuous process innovation of printing companies must start from four aspects: product demand, equipment technology, material selection and job specification. In terms of product demand, printing companies must adopt new horizons to seek business and opportunities from the international printing market, research and develop environmental protection prints, competitive government orders and high-end food and pharmaceutical packaging orders suitable for specific industries, and form product mechanisms that serve high-environmental protection companies. In terms of equipment technology, a printing company can introduce some new equipment and new technologies at the right time, such as flexographic technology with excellent environmental performance, no film from CTP, and technology, and it can also enhance traditional technologies through the transformation and upgrading of traditional technologies. The environmental protection functions, such as offset printing technology from alcohol to non-alcoholic dampening, from water printing to waterless printing; post-press processing from hot to cold, coating film coating from volatile adhesives, water-based glue, Oily glazing to waterborne glazing. In terms of material selection, printing companies need to actively monitor the development trend of international and domestic printing materials environmental protection, grasp the development trend, and enhance the environment-friendly characteristics of printed products, such as the selection of paper or composite material without whitening fluorescent agent on printing materials. , Recyclable and environmentally friendly materials are selected; printing inks are selected as low or harmless water-based inks or soy inks; printing plate materials are selected from plate-washing plates; fountain plates are selected from low-alcohol or alcohol-free fountain solutions; Other auxiliary materials use low-pollution or non-polluting materials. In terms of job specifications, printing companies can establish a set of digital operation systems that comply with environmental protection requirements, high reliability, and high efficiency through self-construction or combination, and establish standardized operation rules for various printing production links to ensure the realization of various environmental protection goals. It also reduces energy consumption, material loss, and manpower loss through the improvement of work efficiency and reliability, and enhances the environmental value of the product and the profit value of the product itself. Therefore, the printing companies must go through the continuous process technology innovation, and go beyond the traditional formula of high-profit and low-cost environmental protection printing products as a whole, and realize new goals of high environmental protection, high value, and high corporate profits.

3. Reducing waste of resources and boosting efficiency of enterprises At the second “Green China” forum, Pan Yuezeng, deputy director of the State Environmental Protection Administration, pointed out that “Humanity is undergoing a new civilized transition and the rapidly developing Chinese economy is facing severe challenges, such as Without radically changing the pattern of high-consumption economic growth, it is very difficult for China to exceed this threshold of civilized transformation.” Although the printing industry is a metropolitan industry that does not possess the characteristics of high pollution, the economic changes caused by environmental protection will affect the printing industry. Renewable paper is widely used in trends such as newspapers and magazines.

In addition to paper, printers also consume a wide range of printed materials such as films, plates, inks, blankets, fountain solutions, washing solutions, and car wash water. The annual consumption cost for a medium-sized company can reach as many as one million. Above yuan, each one percent reduction in material consumption not only produces several times the environmental protection effect, but also increases the efficiency of the company by several million yuan. At present, under the new situation where the printing technology is continuously adopting digital technologies and new technologies, printing companies must take advantage of the environmental protection awareness of the entire people and the power of environmental protection activities, adopt a combination of production, education and research to convert new technologies, new methods and new technologies as soon as possible. In order to improve the production efficiency of printing companies, reduce the consumption of materials, and promote the power of green printing and environmental protection, such as the use of experts and research institutions to print related research results to design technical processes, select suitable printing materials, simplify the operation process and reduce scrap rate. The author once cooperated with many domestic printing companies in the cooperation of production, education and research. The influence of the printing production process alone cannot be ignored. Printing companies can only promote the real efficiency gains by reducing the waste of resources.

In the printing industry, paper is the most consumed material and the most wasted material. Paper is a product of the industrialization of the earth’s forests and is one of the main destinations for the deforestation. According to statistics, there is only one large-scale virgin forest with fewer and fewer trees in the world. In the past 40 years, 50% of the earth's forests (about 3 billion hectares) have been cut down, and only 20% of the rest have not been destroyed by humans. The global greenhouse effect triggered by this will lead to serious ecological disasters in the melting of icebergs in the north and south poles. As a result, the global printing industry has made waste paper recycling and paper recycling an important contribution to environmental protection. The recovery and reuse of waste paper by printing companies can start from technological innovation and waste paper separation and recycling. From the perspective of technological process innovation, printing companies must face the latest printing technology and actively introduce and digest advanced technologies to build their own unique products. The process system, such as the use of CIP3/4 technology, color management technology and CTP technology, has not effectively reduced the number of test papers and waste products, resulting in a dual effect of environmental protection and efficiency. From the perspective of paper sorting and recycling, Printing companies should consciously establish waste separation and collection systems for various processes according to product categories, collect and collect different types of paper, and lay a good foundation for paper recycling to reduce the use of chemicals and water consumption for deinking and pulp fiber separation. At the same time, the increase in the recycling price of classified papers has also contributed to indirect efficiency gains for printing companies. At present, the use of a certain proportion of recycled pulp or all recycled pulp to produce paper that satisfies different requirements has become a trend and a trend. For example, recycled paper is widely used in newspapers and magazines.

In addition to paper, printers also consume a wide range of printed materials such as films, plates, inks, blankets, fountain solutions, washing solutions, and car wash water. The annual consumption cost for a medium-sized company can reach as many as one million. Above yuan, each one percent reduction in material consumption not only produces several times the environmental protection effect, but also increases the efficiency of the company by several million yuan. At present, under the new situation where the printing technology is continuously adopting digital technologies and new technologies, printing companies must take advantage of the environmental protection awareness of the entire people and the power of environmental protection activities, adopt a combination of production, education and research to convert new technologies, new methods and new technologies as soon as possible. In order to improve the production efficiency of printing companies, reduce the consumption of materials, and promote the power of green printing and environmental protection, such as the use of experts and research institutions to print related research results to design technical processes, select suitable printing materials, simplify the operation process and reduce scrap rate. The author once cooperated with a number of domestic printing companies in the cooperation of production, education and research. Only through the digital control of the printing production process, the printing company can reduce the rejection rate by more than 10%, increase the operating efficiency by more than 20%, and reduce the harmful waste by 25% to 40%. %, the stability and reliability of print quality have improved significantly. The stable improvement of printing quality and increase of efficiency have strengthened the competitiveness and brand of the company, pushed the printing enterprises into a benign and sustainable development track with advanced technology, environmental protection of products and winning of the brand, and promoted the win-win situation of environmental protection and efficiency improvement of the enterprise.

4. Conclusions Printing and environmental protection are important topics for the sustainable development of the global printing industry. To achieve the goal of printing and environmental protection, it is necessary not only to strengthen the social responsibility of printing companies and the participation of printing employees, but also to rely on science and technology to promote environmental protection to promote the technical upgrading of printing enterprises. , The material consumption is reduced, the quality is improved and the benefit is doubled, and the sustainable development trend with high environmental protection and high profit is formed. Today, Chinese printing companies that face competition in the global printing product chain can only observe the development direction of printing and environmental protection from a global perspective, and use new technologies, new methods, and new technologies to strengthen their competitiveness. Only in this way can they reduce pollution and advocate environmental protection.
