First, the overall development level of the plate
1. Development focus
At present, the overall trend of China's offset printing plate market is "the output of PS plate is increasing rapidly, the supply of aluminum plate base is insufficient, the new varieties of CTP plate materials are constantly emerging, and the market competition is more intense." The development of offset printing plates is focused on CTP plates, while the current development focus of CTP plates is free of processing plates and UV-CTP plates.
1.1 thermal processing plate
The process-free thermal CTP version has become a key research direction, and new solutions are being introduced. In addition to Fujifilm's purple laser-free processing plates, almost all of the plate manufacturer's process-free CTP plates are based on thermal technology. of. Its new technologies include: polarity conversion technology, laser ablation technology, substrate inking technology, and hot melt technology.
1.2 violet laser free processing plate technology
The violet laser CTP plate is made of photopolymerizable resin plate. At present, the purple laser diode of 30mw, 60mw and 100mw can be used to expose the plate. However, the current purple laser-free processing plate is only free of chemical reagent treatment, and still needs clean water cleaning. In October 2005, Fujifilm exhibited the violet laser chemical-free printing plate Brillia Pro-V in Europe.
1.3 inkjet CTP plate processing technology
Inkjet CTP plate is a new form of CTP-free plate. It has attracted many attentions in the industry due to its simple process, no chemical treatment, no pollution to the environment, low cost and so on. At present, there are two main lines in the development of inkjet CTP plate technology. One is to spray the printed image onto the ordinary PS plate with special ink, which can play a role in shading, and the portion of the PS plate that has not been covered by the ink after exposure is developed. The publication base forms a hydrophilic blank portion, and the ink cover portion is a printed graphic portion; the second is to spray the ink onto the aluminum plate base which has been subjected to graining and anodizing treatment, and the photosensitive layer is not coated, and only needs to form a graphic image. The ink layer is cured and can be printed on the machine. At present, many companies at home and abroad have developed inkjet CTP equipment and plates, such as Jetplate Systems in the United States, Kodak & Jensen in Denmark, Technova in India, Fujifilm in Japan, etc., domestic Beijing Huali Zhicheng, Pu Reiter and others are developing related products.
1.4 smart resin and uniform particle free processing plate technology
This is the technology proposed by Fujifilm. Brillia LH-NN, made with "smart resin material", is a non-thermal technology that can be imaged over a wide spectral range, from UV to IR. Fujifilm is also researching Brillia LH-PJ plates based on "uniform particle technology."
In addition, Heidelberg's Saphira chemical-free plate uses a new latex coating technology called microspheres. The coating does not need to be ablated. The microsphere latex can be bonded to the metal through the 830nm thermal laser of the Super CTP system. On the basis of the plate, the plate is exposed at the same time.
1.5 photopolymer free processing plate technology
The photopolymer technology may use a red laser or a violet laser as a light source to initiate a hardening reaction of the sensitizer. The Kodak negative thermal Direct plate, Agfa N91v Chemfree plate has adopted photopolymerization technology.
Fujifilm's Brillia LP product is a polyester version with high resolution and high sensitivity, and is also developing the Brillia HD PRO-V violet laser polyester version.
1.6 UV-CTP plate
UV-CTP plate refers to CTcP plate material, and its consumables cost is only half of that of other types of CTP plates. It can be used for bright room operation, stable supply of consumables, and attractive market prospects. At present, domestic Lekai Erjiao has launched Huaguang UV-CTP plate.
2. Development level
According to statistics, the total production capacity of national offset printing plates in 2008 was about 360 million square meters, and the total production capacity was 279 million square meters, which was 55% higher than the 180 million square meters in 2006 and 15.38% higher than that in 2007. A record high. The statistics again show that China's offset printing plate has entered a period of rapid development, and China has become one of the world's largest producers of offset printing plates.
2.1 PS version
The PS version of the industry continues to grow and its production capacity continues to expand. In 2007, the production capacity was 300 million square meters, with an annual growth rate of 15%. In 2008, the PS version produced 218 million square meters, an increase of 5.59% over 2007 (see Table 1). The PS version of the industry is gradually transitioning from an extended development to a connotative development, which is conducive to the healthy and steady development of the industry.
2.2 CTP plate
Since 2007, China's CTP plate production has achieved rapid development. According to statistics, in 2007 China produced a total of 35.6 million square meters of CTP version, an increase of about 92%. In 2008, the production volume of CTP version was 61 million square meters. In 2007, the growth was about 72.2%.
Fujifilm, Kodak, Agfa's three major plate suppliers have launched a number of plate production lines, and domestic Sichuan Juguang and Lekai two plastics have increased their development efforts. The CTP plates they produced have achieved good results in the market. . There are also a large number of production plants are actively exploring the development of different types of CTP plates.
2.3 Market conditions
In 2008, the actual total sales volume of offset printing plates in China was 269 million square meters, an increase of 11.72% over 2007. The sales volume of the PS version was 211 million square meters, an increase of 5% over 2007. The sales volume of the CTP version was 58 million square meters, an increase of 71.36% over 2007. The annual sales of plate materials was 8.458 billion yuan, an increase of 15.86% over 2007. The sales of PS version was 5.482 billion yuan, and the sales of CTP version was 2.976 billion yuan. The total profit is about 350 million yuan, and the average profit rate of the whole industry is about 4%. The profit of CTP plate is much higher than that of PS.
In 2008, despite the huge impact of the international economic crisis, the offset printing plate industry maintained a growth rate of more than 15%, which benefited from the rapid growth of sub-exports. The annual export volume of offset printing plates was 101 million square meters, an increase of 22% over 2007. The PS version exported 65 million square meters, basically the same as in 2007. The CTP version exported O.36 billion square meters, an increase of 103.93 over 2007. %. It can be seen that the export volume of the CTP version has increased more. The growth of the traditional PS version, whether it is domestic consumption or export volume, has a very low growth rate. This shows that the demand for high-end plates at home and abroad is getting bigger and bigger, and the production capacity of domestic CTP plates is getting stronger and stronger.
From the perspective of industrial distribution, China's offset printing plate manufacturing industry is developing towards large-scale and regionalized development in the direction of the world's printing plate processing plants.
In terms of large-scale development, international brand photographic materials companies have taken the lead. Fujifilm, Agfa and Kodak have formed a production capacity of about 70 million square meters per year in China, reaching 100 million in 2009. Square meters. Domestic Lekai Erjiao has an annual production capacity of 60.3 million square meters of offset printing plates in 2009.
In terms of regional development, at present, the number of reel plate production lines in the country has actually reached more than 80. It has formed the Central Plains offset printing plate industry belt with Lekai two rubber as the leader, and the Chuanxiu offset printing plate industry led by torchlight. With the belt of the Bohai Sea offset printing plate industry centered on Beijing Dongyan Suburb, and the Yangtze River Delta offset printing plate industry belt including Suzhou and Wuxi, the dream of China becoming the world's printing plate processing factory has become a reality.
Second, problems in development and development proposals
Despite the rapid development of China's offset printing industry in recent years, the production capacity, production volume and sales volume are maintaining rapid development. However, the quality and technical level of domestic plate production are still far from international manufacturers. At the same time, despite the rapid growth of the industry, the overall profit margin of the industry is not high, and the continuous decline in the profit margin of the entire industry may have a negative impact on the healthy development of the industry. In particular, the PS version of exports continued to grow faster, and the price was welcomed by the market. However, low-price competition will not only cause the loss of corporate profits, but also trigger anti-dumping problems in the international market, ultimately jeopardizing the interests of the entire industry.
1. PS version of production conditions and quality levels need to be greatly improved
1.1 aluminum plate quality is unstable
In recent years, the price of aluminum ingots has risen, and some of the quality of domestically produced aluminum coils are unstable, which affects the apparent quality of aluminum plate bases and the quality of electrolytic sandblasts. Domestic aluminum plate-based surface black bars and bright spot defects are more common. Therefore, as a version The main raw material for the production of aluminum, the quality of the aluminum plate needs to be greatly improved, and the electrolytic properties and apparent quality of the aluminum plate still need to be improved.
1.2 production conditions are not strict
Some plate manufacturers have problems in the production conditions, the production workshop is not well sealed, the air is not purified, and the ground is floating, which seriously affects the product quality.
1.3 production equipment level is not high
Many domestic plate production lines have too low a speed, and the control precision is not high, which affects the quality of the plate and the production efficiency. Many of the cutters installed on the production line are not required. There are many burrs on the edge of the plate, and the cutting size error is large, which affects the use.
1.4 lack of plate production standards
Standardized control of products still requires a large amount of production site management, otherwise the quality of the products will not be improved.
2. Increase the development of CTP plate materials and develop high-end products
The development, development and production situation of China's CTP plate material is still grim. Although the plates of Lekai Erjiao and Sichuan Juguang have gradually gained a certain market share, their status has not yet been consolidated. In addition, there are still seven or eight companies in China claiming production. CTP plate, but there are no mature products on the market.
At the same time, the matching problem between CTP plate and CTP equipment also needs to be paid attention to. Each type of plate has different special properties. If you rely on a certain supplier or a brand of plate for a long time, it limits the user's choice and For plates of the same type and with the same wavelength, the plate should be adapted to more models.
All plate manufacturers should make full use of the excellent situation of reform and opening up, strengthen international cooperation, actively participate in technical exchanges at home and abroad, actively absorb and absorb advanced technologies at home and abroad, and improve the quality of their products as soon as possible.
3. The scale of the company is uneven and the competitiveness is not strong.
The scale and strength of domestic plate production enterprises are uneven. Many manufacturers' products are in short supply. There are also a few enterprises whose products are of unstable quality, equipment is not closed, funds are not well-circulated, production lines are shut down and even stopped. In addition, domestic companies have patented technologies, especially brand-name products with independent intellectual property rights. Many companies do not pay attention to the development of new products and the improvement of traditional products.
Third, the development forecast of the plate
1. Technology development forecast
1.1 The 1PS version will still be the mainstream plate-making method, and with the improvement of equipment performance and print grades, different requirements are placed on the performance of the PS version. For example, newspaper printing hopes that the printing plate has the characteristics of short printing time and high printing durability. Fine printing requires high resolution of the photosensitive layer of the printing plate, good reproducibility of the dot, and uniformity of the large-area flat net. This requires the PS plate to be in Stabilize and improve its versatility while considering the particularity of the user.
1.2 China's application of CTP plate technology will be further accelerated. Due to the continuous expansion of domestic CTP plate production capacity, most of the world's mainstream brands of CTP plates can be produced in China. The variety of sources and variety diversity is affirmative to users, and the promotion of production enterprises is self-evident.
●CTP plates will be developed in the direction of multiple types, multiple varieties, multi-purpose, easy operation, time saving, stable quality and more environmental protection. This variety, multiple varieties is a dynamic balance.
● The multi-variety situation of the plate will exist for a long time. Due to the variety of printing methods, printing quality and publishing time requirements, people will choose equipment and plates as needed, and all kinds of plates will have their own markets.
● The process-free plate technology will further mature. As the country attaches importance to environmental issues and sustainable development, the free-process plates will be of concern to more plate manufacturers and users. The reliability, stability and printability of the process-free plate itself will be further enhanced with the development of technology.
1.3 Increased likelihood of 3PS plates entering the CTP system
In recent years, the world's major plate manufacturers have introduced high-sensitivity plates for UV-CTP plate making. With the increasing sensitivity of 365nm, 375nm laser heads and traditional PS plates, UV-CTP will become the mainstream CTP technology. one.
In addition, CTdP (Computer To Digital Plate) has recently appeared in the industry. Longma Aluminum uses a 405nm single-beam optical laser from the Lausanne digital plate-making equipment in Switzerland to directly plate the PS plate.
2. Market development trend
2.1 The 1PS version will continue to be the main force in the offset printing plate market, but the use of CTP plates will continue to grow. From 2006 to 2008, the domestic consumption of CTP plates accounted for 8% of offset plate consumption. , 13%, 14%. According to statistics, the consumption of CTP version in developed countries has reached more than 70%. Compared with the changes in the consumption of domestic plates, coupled with the decline in the price of CTP equipment and plates, the PS version still dominates the market in 2009, but its proportion has decreased with the increase in the number of CTP plates.
2.2 The development of new printing technology will affect the growth of offset printing plate consumption. As the demand for personalization grows, digital printing will compete for a portion of the offset printing market, which in turn will affect the consumption of the PS version and the CTP version. Therefore, whether the total consumption of offset printing plates will continue to grow will remain to be seen.
2.3 The export volume of 3 plates will continue to grow. China's PS version of production has grown year after year, and there has been a situation of oversupply. More and more international manufacturers have increased their investment in producing CTP plates in China. Some manufacturers have already opened 8 editions in China. At the same time, domestic plate producers are also stepping up the development and production of CTP plates. In the future, if there is no major fluctuation in domestic export policies and exchange rate levels, offset printing plates will continue this strong growth momentum for some time. Foreign markets have become an important fulcrum for the development scale of China's offset printing plate industry. At the same time, offset printing plates have become the leader in China's printing equipment industry to explore the international market and occupy the international market on a large scale. Of course, we must have a clear understanding of this: on the one hand, we must continue to nurture and care for this market and make it develop healthily; on the other hand, we must always pay attention to the development trend of the world economy and the policy direction of domestic import and export commodity taxation, and adjust the marketing of enterprises at any time. Strategy. In terms of exports, we must pay special attention to increasing the production of CTP plates with high technology content and high added value.
Under the leadership of the development of the plate, ink and paper industry, although the industry and the industry have been affected by the international economic crisis since the second half of 2008, the domestic printing equipment industry has achieved a total output value of 31.2 billion yuan, an increase from the previous year. 12.7%. Among other printing consumables, printing rubber rollers still increased compared with 2007, and printing blankets and anodized aluminum decreased compared with 2007.
We should see that there is still a considerable gap between China's printing per capita consumption and developed countries. This shows that China's market has great potential for development. In the future, China's printing equipment should not only improve product output, but also pay more attention to improving product technology. To adapt to the needs of today's multi-color, high-speed, fast-drying, pollution-free and low-consumption modern printing.
