Analysis on the current situation of China's offset printing plate industry

at present, the general situation of China's offset printing plate market is that "the output of PS plate is increasing rapidly, new varieties of CTP plate are emerging, the market competition is more intense, and the supply of aluminum plate base is insufficient". This paper will use more detailed figures to analyze the current situation of printing plates in recent years, hoping to provide useful reference for the insiders and entrepreneurs

ps edition industry pays attention to quality while putting on new lines

production and sales of PS edition in 2003 30 ~ 94hrg

at present, there are about 30 PS edition manufacturers (mainly those with reel type PS edition production lines) in China. In 2003, 2 ~ 3 new PS edition factories were built, with a total of more than 10 new PS edition production lines. The speed of the new PS version production line is generally more than 10 m/min, including 1 production line of 60 m/min, 2 production lines of 30 m/min and 1 production line of 20 m/min. Only these four production lines operate at full capacity, the annual production capacity of PS version in China can be increased by 45million square meters. Even if the output is increased by 1/3, the total output of PS version in 2003 can be increased by 15million square meters on the basis of 80million square meters in 2002. According to incomplete statistics, the total output of PS version has exceeded 100million square meters. If the output in 2003 is 95.5 million square meters, the output of PS version has been increasing by 20% ~ 30% in recent years, as shown in Figure 1

the growth rate of PS version output in the past two years was significantly higher than that in the previous two years. The growth rate from 1999 to 2001 was less than 20%, while the growth rate from 2001 to 2003 was 30%

the continuous growth of PS version output has also intensified the competition in the PS version industry. On the surface, the inventory of each PS version manufacturer is small, but in fact, price competition has always existed. At present, the aluminum plate price has been rising again and again, but the PS version sales price has been stable or even declining, which shows this point; In addition, some manufacturers have experienced insufficient operation and low equipment utilization

fortunately, the number of exported PS versions has increased to a certain extent; In 2002, China exported 4.25 million square meters of PS version. In 2003, the output of PS version was 7.17 million square meters. The export growth rate reached 68%

pay more attention to product quality

in July 2003, it was learned from the Symposium of some printing plants held by the printing equipment branch of China printing and equipment industry association that users reported that the quality of the plates of most plate factories now in use has been improved to varying degrees, and there are few plate changes due to quality problems. The plates are mainly faced with more subtle and specific process problems in the use process. For example, the photosensitive speed of the plate, the tolerance of development, the convenience of operation and whether the after-sales service is in place. At present, the larger plate manufacturers pay more attention to the quality and performance of products. For example, they have increased the rough surface treatment process and primer process in the production process, improved the color difference changes before and after the plate exposure, and made the printing operation more scientific and simple, and the quality more stable and reliable

progress of CTP plates

with the popularization and application of CTP technology, the installed capacity of CTP equipment is increasing, and the domestic voice for domestic CTP plates is also growing. According to statistics, the installed capacity of CTPs in China was 61 before September 2001 and 226 in September 2003 (the latest statistics of the printing manager department in September 2003). Although the absolute value of this figure is small, and the total number of versions used cannot be compared with the number of PS versions, it has attracted great attention of PS version manufacturers. Domestic lucky group took the lead in launching thermal preheating negative CTP plates, and then expanded to other forms of CTP plates; The Institute of physics and chemistry of the Chinese Academy of Sciences has started to establish a production line after the successful pilot test of silver salt CTP plate; In April2003, Shanghai Institute of printing technology launched a non silver photopolymer CTP plate for laser direct plate making, which is another type of CTP plate after silver salt CTP plate and thermal CTP plate, marking that three major direct plate making plates in the world have been successfully developed in China. These achievements will promote the popularization of CTP technology in China in the future

at the same time, China's CTP market has also attracted famous foreign photosensitive material manufacturers to settle in China one after another and participate in the competition in the plate industry

after Fuji Xingguang Co., Ltd. was jointly established by Fuji company of Japan and China Institute of Printing Science and technology, the original production line 1 was first technically transformed, the speed was increased from the original 15 m/min to 18 m/min, and devices such as coating the rough air guide layer were added. Not long ago, the high-performance VP and vps-a new PS version were launched, and their market share was rising. Now the second production line with a speed of 30 m/min adopts the advanced technology of Fujifilm company of Japan, which can produce high-quality PS and CTP plates. In the spring of 2004, the company will also launch a thermal positive CTP version suitable for various direct plate making machines such as Creo, big Japan screen, Heidelberg, Agfa, etc., and will launch a photosensitive violet laser CTP version suitable for Fujifilm's vx-9600ctp, v-9600ctp, v-6000ctp and other models at the end of 2004

in order to meet the needs of CTP printing plate market, Agfa has built a printing plate factory in Wuxi, China. Since breaking ground in Wuxi New Development Zone in 2002, it took 18 months to complete in september2003. The newly built plate production line can run at a speed of 60m/min, with a maximum annual production capacity of 25million square meters, and can produce ordinary PS plates and CTP plates

although Kodak poly optics has a small factory in Tianjin, it has its own characteristics. It is very simple to provide users with the whole roll of PS or CTP plates produced abroad after cutting and packaging in China

the three major photosensitive material companies in the world, Kodak Polaroid, Fuji and Agfa, have established plate production bases in China in different forms, which will further promote the development of plate manufacturing technology in China and promote better seismic performance; The higher degree of prefabrication and assembly, the application of CTP technology in China, increases the output of high-quality PS plates in China, and inevitably adds high-level competitors to the booming PS plate industry in China. Therefore, the domestic plate industry will face a test of reshuffle

problems faced by offset printing plate industry

offset printing plate is an important part of printing equipment. At present, we should actively promote the development of high and new technology, vigorously improve the grade of products, strengthen the supporting of raw and auxiliary materials, and create an orderly competitive environment

new PS production lines should be carefully built.

in view of the fact that the production capacity and output of PS have exceeded the demand, it is not appropriate to build more PS production lines in the future. The development of PS version should strive to improve the quality, grade and variety, and strive for more products to reach the level of international or domestic famous brand products. To expand the scale of enterprises, we should proceed from the reality, from the technical strength, talent strength and new product development capacity, and consider the market capacity, so as to avoid waste caused by insufficient construction

seize the development opportunity of CTP

with the progress of printing technology, the number of manufacturers using CTP plates is increasing year by year. The increase of CTP plates will inevitably lead to the decrease of PS plate consumption. Although the installed capacity of printing press and printing equipment will increase every year, we can not live up to the trust of the majority of users and will never develop at a rate of 30% like that of PS version. At present, CTP plates mainly have three types: thermosensitive resin plate, photosensitive resin plate and silver salt composite plate. It will take some time to realize large-scale production

accelerate the development of supporting materials

both PS and CTP versions need aluminum plates as the plate base. At present, the production capacity of PS version in China is close to 100million square meters, while the supply of aluminum plates is less than 30000 tons, that is to say, more than half of the aluminum plates need to be imported. In addition to the insufficient quantity, the quality of domestic aluminum plates is also deficient. If relevant fields can seize the opportunity to improve the quality and output of aluminum plates from the perspective of equipment and technology, it will undoubtedly promote the development of printing plates

ps version of other supporting materials, such as photosensitive adhesive, sulfonyl chloride, resin, solvent, dye and packaging materials, should also make its products gradually become brand-name and large-scale, and stabilize product quality. PS version manufacturers can divide the work properly to make a product more refined

calmly deal with the domestic and foreign markets

ps version should not only focus on the domestic market, but also actively explore the international market. To participate in international market competition, we should abide by the principles of foreign trade, not only consider the price factor, but also emphasize the quality and variety, so as to enhance the brand's competitive awareness and win with reputation. At present, some enterprises' export prices are too low and compete at low prices, which not only disturbs the normal plate export prices, but also is not conducive to the domestic PS plate market moving towards the international market
