Several problems in the development of gravure printing machine (2)

3) gravure printing is seriously polluted

among the three main printing methods of offset printing, flexographic printing and gravure printing, gravure printing causes the most serious pollution of digital display. In order to reduce pollution, foreign printing industry has taken effective measures and achieved good results. For example, the carbon paper corrosion gravure plate making process with severe pollution has long been eliminated; In the process of pre-processing the cylinder body of the printing plate, spraying glue to corrode the gravure plate and making electronic engraving gravure plate, the treatment of waste liquid is strengthened to reduce the pollution of gravure plate making; In Xiuban printing, gravure water-based inks have been successfully developed in the mid and late 1990s. All paper printing uses gravure water-based inks, and plastic film printing also does nothing as scorecard inks. This is the main reason why foreign gravure printing cannot maintain a 15% market share at present

at present, the waste liquid treatment in the process of plate cylinder pre-processing and gravure production has developed slowly in China; In printing, whether paper gravure printing is not plastic film gravure printing, because the price of salivary ink is too high, solvent gravure printing ink is basically used

solvent gravure printing ink is an important pollution source of gravure printing. For example, chlorine hydrocarbons are released during the production of the ink to pollute the atmosphere and destroy the ozone layer of the earth; Toxic substances are discharged during use, which is harmful to human health, and there is a risk of flammability and explosion; The organic solvent remaining on the surface of the printed matter will be directly polluted by seeping into the package. For this reason, the replacement of solvent based gravure printing ink with water-based gravure printing ink has become the basic requirement for gravure printing in the world today, especially for the printing of tobacco, alcohol, drug packaging and food packaging, the use of solvent based printing ink should be prohibited. It can be seen that it is urgent to promote the use of water-based gravure printing ink

The year 2002 is the first year of China's entry into WTO. China's entry into WTO provides opportunities for the development of gravure printing technology in China, but it also brings new challenges. In particular, China will allow foreign wholly-owned enterprises engaged in packaging and printing to enter the Chinese market. They have advanced technology and equipment, abundant funds and scientific management, which will bring great pressure and impact to the domestic gravure market. For this reason, we must vigorously carry out the organizational adjustment of the enterprise, avoid low-level repeated construction, increase the investment in the research and development of new products and materials, and provide the domestic gravure printing market with much-needed gravure printing equipment and materials. Therefore, it is suggested to do the following work well

1. pay close attention to the organizational adjustment of enterprises

in the coming period, the organizational adjustment of gravure printing enterprises in China should focus on two aspects:

1) solve the large and comprehensive production mode of enterprises, and develop professional and socialized production

the organizational structure of gravure printing enterprises in China, especially gravure machine manufacturing enterprises, mostly belongs to the olive model, that is, the middle is heavy and the two ends are light: the production of parts and components of products is almost all produced internally by the enterprise, accounting for an excessive proportion; However, the ability of product research and development, marketing and after-sales service, which determine the life of enterprises, is too weak and accounts for a small proportion. In this way, the competitiveness of products will inevitably be weakened. After organizational adjustment, the olive business model should be transformed into a dumbbell business model, that is, the enterprise only completes the production and product assembly of a few parts, and turns the production of parts with a large proportion to the society, which is undertaken by socialized and professional manufacturers, focusing on strengthening product research and development, marketing and after-sales service, so as to enhance the competitiveness of the enterprise

2) realize enterprise merger, reorganization and association, and form three small enterprises

at present, three enterprises in the domestic printing machine industry have preliminarily completed enterprise mergers, reorganizations and alliances, namely, beiren group, Shanghai printing and packaging machinery company acquired Akiyama company of Japan, and Lianqiang printing machine group, which was jointly established by Jingdezhen printing and packaging machinery company, Weihai printing machine company, Tangshan Yuyin and Changchun printing machine factory. This is the first step of enterprise organization adjustment. After a period of practice, we will continue to sum up experience and improve it, and we will certainly receive good results

at present, there are about 20 domestic manufacturers of gravure printing machines, which are basically large and all small and all inclusive production modes, and there are low technical level and repeated production conditions to varying degrees. If the necessary enterprise mergers, reorganizations and alliances are advanced according to their respective advantages, and the three small enterprises are gradually formed, namely, small and specialized, small and refined, and small and strong enterprises, the product technology level can be greatly improved, the production scale can be expanded, and the market competitiveness can be enhanced

2. Research and develop medium and high-grade gravure printing equipment, and limit the three basic configurations of low-grade gravure intellectualization: mainframe, microcomputer, and printer printing machine production

on the whole, at present, China's domestic gravure printing machines and several products are close to the medium-grade technical level, and most of them belong to medium and low-grade products. From the perspective of market demand, domestic low-grade gravure printing machines are surplus, while medium and high-grade gravure printing machines are insufficient. In order to change this situation, the following three suggestions are put forward:

1) encourage the research and development of medium and high-grade web gravure printing machines

in order to slow down the passive situation that the medium and high-grade web gravure printing machines mainly rely on imports, the state-owned and relevant departments should give encouragement and support to the enterprises developing such products in policy, so as to gradually increase the market share of domestic medium and high-grade gravure printing machines

2) necessary restrictions on the production and use of low-grade gravure printing machines

among the packaging and printing enterprises, a considerable number of small and medium-sized enterprises in China now have backward equipment, low printing quality and serious pollution, especially the working environment of many enterprise workers is very poor. Such enterprises that waste materials, consume energy and cause serious pollution are detrimental to both the country and the people. At present, many domestic enterprises have gradually begun to implement ISO14000 international standards, and strictly restrict the production and use of such products

3) strengthen the research and development of sheet fed gravure printing machine

paper container printing is one of the main markets of gravure printing, especially the packaging printing of high-end tobacco, alcohol, drugs, cosmetics and other commodities. Most of them are typical examples of small batch, multiple varieties and high quality. Sheet fed gravure printing machines and combined gravure printing machines combined with offset printing or flexographic printing are the best choices for this kind of products. Therefore, increasing the investment in the development of sheet fed gravure printing machine will play an important role in stabilizing and expanding the gravure printing market

3. accelerate the pace of research and development of gravure water-based inks to adapt to the new situation after China's entry into the WTO

as mentioned above, it has become an inevitable trend for the development of gravure printing to replace solvent based inks with water-based inks. If we can't supply the water-based ink needed by gravure printing market as soon as possible and still use solvent based ink for printing, these prints can't enter the international market, and the existing domestic gravure printing market will also be impacted by foreign sole proprietorship. Therefore, to develop gravure printing technology in China, we must accelerate the pace of research and development of gravure water-based ink

at present, there are more than 300 ink factories in China, including 6 manufacturers with an annual output of more than 5000 tons of CPLD (complex programmable logic device). In 2001, the total output of ink in China was 200000 tons. Although the research and development of gravure water-based ink has begun, it has not yet formed a certain production scale. According to the current market share of gravure printing, the country needs about 20000 tons of gravure printing water-based ink every year. Therefore, the task of eliminating solvent based gravure inks and promoting and using water-based inks is still very arduous. As long as the insiders pay attention, increase R & D investment and carefully organize, they can provide the water-based ink needed for the gravure printing market and make an important contribution to the development of gravure printing technology in China
