After the awareness of environmental protection has gradually penetrated the hearts of the people, accelerating the development of green printing has become a fashionable topic. To this end, the General Administration of Press and Publication and the Shanghai Municipal People's Government jointly opened the first green creative printing demonstration park in Jinshan, Shanghai in October 2010. The printing industry emphasizes that the road to green environmental protection is undoubtedly the progress of society, and it is also a correction for the fact that printing is a green industry for quite some time.
Compared with the high pollution and high energy consumption of the paper industry, the printing industry is a low pollution, low energy consumption industry, but it is definitely not in the green category. There are noise, waste gas and waste water discharge in the printing production process. It has a certain impact on the normal life of the surrounding residents. Promoting the greening of the printing industry can reduce the negative impact on the environment and the responsibility of the printing industry to protect the environment.
Going green and environmentally friendly
Printing production needs to be green, related to machinery manufacturers, related to material suppliers, and related to paper production... because efforts to reduce the noise generated by friction of production equipment can help improve the production environment of workers and reduce external emissions of noise. The use of non-toxic and harmless raw and auxiliary materials not only helps the health of production workers, but also effectively reduces the disposal of waste products. More importantly, it can also give users peace of mind. As for the increase in the proportion of recycled paper, it can effectively reduce the deforestation of the forest and prevent the earth from accelerating warming.
Today, the road to green production and environmental protection in printing production should be said to have basic conditions. Equipment suppliers, especially overseas high-end equipment suppliers, have done a very good job in the continuous improvement of equipment, the energy level of equipment is constantly improving, the noise is declining, and large-scale enterprises through centralized gas supply and centralized ink supply. The noise emitted by the air pump is greatly alleviated, and the amount of solid waste such as ink tanks is reduced; the promotion and use of soybean ink, the promotion and use of professional detergents, and the introduction of flush-free CTP plates are all green for printing materials. The road provides the possibility; although the total use of recycled paper in production has not been large so far, there are no obstacles in the production and use of recycled paper.
The added cost cannot be left alone
If there is any bottleneck in promoting green printing, who is going to pay for the printing cost increase caused by the green printing road?
The current situation proves that the cost of using environmentally friendly equipment and raw and auxiliary materials is higher than that of ordinary materials. In order to prevent the leakage of exhaust gas, it is better to have two combustions in the oven. In the second non-drying combustion process, the harmful substances that are volatilized are burned out as much as possible to reduce the emission to the atmosphere. But there is no doubt that the procurement cost of equipment has increased, and the production costs of enterprises have also increased.
In the printing process, the use of soy ink to replace the commonly used ordinary ink, or the use of a central ink supply system to replace the currently widely used small can ink, the solid waste to be treated must decline, but also face the problem of increased cost. Replace the ordinary CTP plate with a flush-free CTP plate and replace the steam oil with a professional cleaning solution... All of this can be done. The key is because the environmental protection is strengthened. Who will pay for this new cost?
In developed countries, it is only natural for consumers to bury themselves. Because taking the road to environmental protection is a good thing for the benefit of the country and the people, although it increases the cost of purchasing products for consumers, it reduces the expenditure on the state's governance environment, and citizens can accept it. In foreign countries, the same products are environmentally friendly and not environmentally friendly because of the different materials used. Many consumers prefer to buy environmentally friendly products at high prices without buying non-environmental products. Obviously, the standard of living and the level of thought of the people in our country have not yet reached this realm.
The most typical case is that the work of smoking bans in public places during the 11th Five-Year Plan has had little effect. Is it that smokers do not know that smoking is harmful to their health and will also affect the health of passive smokers? But the object of smoking is far from being to take responsibility for reducing environmental pollution. Now, everyone wants to strengthen environmental protection and improve the living environment, but they all hope that the government will pay the bill, or in other words, they hope that after strengthening environmental protection, they will not increase their personal expenses.

Take the green printing road to start from reality
In 2010, Shanghai selectively tried to print environmental protection textbooks, still using ordinary printing paper, and printing equipment to traditional offset printing for flexographic printing. The result book is out, and the social response is also very good, but the cost of teaching materials is almost doubled. In the middle, there are factors such as the small size of the printing flexo device, which increases the cost of binding, but the use of relatively environmentally friendly equipment and The fact that materials lead to rising costs is an objective fact.
Regarding the question of who will pay for the increased cost, the parties involved in this work have been pushing each other for a long time. It is finally determined that the government subsidizes a part, the publishing house has more parts, and the printing factory takes over part of it. If a book can still be handled this way, after the printing of environmental protection textbooks is greatly increased, who will pay for this part of the new cost? If the printing of ordinary books is also changed to environmentally friendly materials, will readers further reduce the purchase of books? What?
In the past few years of reform and opening up, the rapid development of the printing industry has already led to greater production capacity than market demand, and the wages continue to decline. The book printing industry, which faces the challenges of the Internet and digital printing, has a weaker viability and has already entered the meager profit channel. The cost of taking the green printing road to the printing factory to bear the burden is obviously not available; after the textbooks were revised by the government in 2006, the profit of the publishing house is controlled within 5% of the code ocean, and it is not realistic for them to pay the bills; The government will pay more for this bill.
Moreover, if some people have changed to flexographic printing, what is the capacity of the original offset printing equipment? Further, the textbook itself is in a turbulent period of whether it is replaced by electronic paper books. The Shanghai Municipal Education Commission has already proposed Within five years, the use of e-books will be gradually promoted to replace the timetable of traditional textbooks. After the textbooks are converted into flexographic printing, once students use electronic paper books, will it not cause a large number of flexo printing machines to idle?
In short, it is a good thing to take the green printing road, but this should be a gradual development direction, and should not be wavered, and can not expect to be completed overnight. Grasping the work should also be in the right direction, persevere, and can not be keen to cater to the market hotspots. This year, one will be caught and one will be caught next year. As a result, the bears and the sticks will not achieve anything. The company expects everything to proceed from reality and move forward step by step.
