Since CTP was first exhibited in Druba, the domestic CTP market has been a battle for market competition for imported CTP suppliers. In the past two years, domestic CTP equipment has also quietly debuted. Since domestic CTP manufacturers have few large manufacturers, After the launch of CTP, it has not been as fanciful as Founder Diaolong. Although the domestic CTP is not only inferior in technical performance to foreign equipment, in fact, some are not really "domestic" or "CTP", but as a pioneer of domestic CTP They are also working hard for small and medium-sized printing companies to embark on the road of CTP application. This CTP device combines the actual situation in China, has its own characteristics, and has certain development potential.
The first to appear as a domestic CTP was the inkjet CTP. This kind of equipment just follows the concept of CTP technology. It is not the laser imaging of CTP plates, but only the inkjet equipment is used to directly transfer the original data information to the film, PS plate and paper. The main features of these devices are: high-precision inkjet printer is the main component of inkjet CTP system, the most "like" CTP is to spray images on the PS version, after some processing can also be printed on the machine. But compared with the real CTP, this can only be regarded as a toy.
Early suppliers of inkjet (manuscript data directly to film) CTP equipment active in the Chinese market include Beijing Stone Investment Co., Ltd. and Shenyang Boji Technology Development Co., Ltd. The "Sitong Inkjet Plate-making System CTP-2000" of Beijing Stone Investment Co., Ltd. is composed of input scanner, PC computer, Stone RIP software, and Epson inkjet printing machine. The consumables are bright room film, special PS version, special digital Proofing paper. This system uses micro-voltage technology on the basis of traditional printing, and uses inkjet equipment to output graphics directly to film, PS plate and paper, without the process of developing, fixing and washing the film. The average market price is 130,000 to 150,000 yuan, suitable for domestic small and medium-sized printing enterprises. In addition, Shenyang Boji Technology Development Co., Ltd. started from the purchasing power of domestic small and medium-sized printing plants. Since 1998, it has introduced a technology that directly coats a film on the film and directly prints the film using an Epson inkjet printer. Its characteristics are: Graft the graphic information on the ordinary PS version through the coating.
Another inkjet CTP system is to use an inkjet printer to transfer the graphic information directly to the aluminum plate. Beijing Shangpin Plate-making Co., Ltd. introduced this CTP system, which is mainly improved on inkjet ink and aluminum base plate. Inkjet ink is a special ink that can be printed on smooth coated paper and smooth On the aluminum plate, the curing speed is fast, there is no overflow, and the graphics will not change into flowers. The graphics printed on the aluminum plate have good ink affinity after curing, the blank part of the aluminum plate is hydrophilic, and the printed dots and digital proofing dots are completely Consistent. According to Wang Baizhi, general manager of Beijing Shangpin Plate Making Co., Ltd., investing in inkjet (to the aluminum version) CTP system requires about 500,000 yuan, 50 square meters of office conditions can replace the past film (exposure, display, fixing), manual proofing Printing, proofing PS plate, development, traditional proofing, manual printing plate, printing PS plate, development and other complex processes are very suitable for the needs of small and medium-sized printing companies.
Peking University Huatong's silver salt and thermal CTP
Domestic CTP equipment that belongs to the same technology type as foreign CTP products may be the earliest CTP equipment developed by Peking University Huatong. In 1997, Peking University Huatong established Xiamen Peking University Huatong High-Tech Industrial Co., Ltd. in a joint venture with the Peking University Physics Department according to the actual situation in China. Peking University Huatong avoids research risks as a starting point. In general, it focuses on the design of lasers and develops the BH-3000 type silver salt computer direct plate-making machine. From its inception in 1999 to the present, the BH-3000 has undergone a transition from 4 lasers to 32 lasers. On November 4, 2000, the product passed the product quality test of Beijing Electromechanical Product Experimental Station, and its technical indicators have reached the level of similar foreign products in the late 1990s. At the end of April 2000, the equipment trial printed about 200,000 copies of "Weapon Knowledge" magazine in Beijing Foreign Language Printing Factory. The quality was affirmed by users, and the accuracy and plate-making speed basically reached the expected requirements, but compared with foreign imported equipment There is a certain gap.
Silver salt CTP has always occupied an absolute advantage in the newspaper industry, while in the commercial market, thermal CTP is still playing the leading role. After accumulating silver salt CTP research and development strength and excellent team strength, Peking University Huatong began to enter the development stage of thermal CTP. In September 2002, Peking University Huatong High-tech Industrial Co., Ltd.'s work on China's first CTP equipment in line with international mainstream technology was nearing completion. The accuracy of the thermal CTP currently introduced by Peking University China is 2540dpi, the plate-making speed can reach 12 sheets / hour, and the number of scanning channels is 32. It can achieve semi-automatic versioning, which is basically the same as the performance of foreign equipment. Peking University Huatong pays attention to color reproducibility and resolution when developing thermal CTP, and the equipment performance can fully reach the high-end printing level.
Miao Yuan, head of the CTP project of Peking University Huatong High-Tech Industrial Co., Ltd., said: "CTP should be divided into two parts in terms of a project: One is the process part. The CTP equipment needs to have digital proofing, color management, and digital workflow. Unified coordination; Second, the equipment part, the equipment itself should have certain advantages, such as full dots, high printing resistance, accurate overprinting, fast ink application, etc. "In order to enable the target object to purchase domestic equipment, Peking University Huatong is ensuring its Under the premise of the same precision and the same scanning speed as the international equipment, the equipment structure is simplified as much as possible, the supporting use of automation equipment is reduced, and the product price is reduced to a level acceptable to small and medium-sized printing enterprises, so as to break the domestic The "noble, modern" CTP system is beyond reach.
CTP
In addition to Beida Huatong, the number of manufacturers participating in the development of domestic CTP equipment is increasing. As a supplier of printing equipment, Duoyuan Electric Group has been active in this field. At drupa2004, Duoyuan demonstrated the self-developed DYCTP600l thermal CTP system. According to the company's publicity materials, this is called "the first CTP product in China in the real sense, Poly Electric has launched its own domestically produced CTP equipment." The thermal CTP equipment introduced by Duoyuan Electric adopts 830nm laser, outer drum design and preheat-free thermal plate, which is in line with the current international CTP development trend.
CTP of Hanhua
At ChinaPrint 2005, the CTP systems produced by two domestic companies were exhibited, which aroused the strong interest of visitors. The two enterprises are Hangzhou Kelei Electromechanical Industry Co., Ltd. (hereinafter referred to as Kelei) and Shenzhen Han's Computer Plate-making Equipment Co., Ltd. (hereinafter referred to as Han's). According to reports at the time, "These two companies launched CTP equipment in the true sense this time, instead of the pseudo-CTP system that was previously mixed with fisheyes."
Han's Laser Holdings Yingkou Guanhua gained complete marketing channels in the printing industry and became a complete solution provider from CTP sheet, CTP plate making machine to color offset printing machine. Laser plate making and printing equipment have become another company's future growth. Highlights. However, Han's laser has not used CTP as the main product. Yingkou Guanhua Group sold 10 CTP plate-making machines to the United Kingdom, Russia, Philippines, New Zealand and other countries on drupa2004, and domestic CTP plate-making machines were exported.
Corey's CTP
Hangzhou Corey exhibited three devices at the China Print 2005 exhibition. Among them, phoenix Phoenix and python Python used 830nm thermal laser light source and 405nm purple laser light source respectively. These two light sources are also the mainstream CTP light sources in the international CTP market. In this sense, Cray's CTP products have already reached the international advanced level. The Silver Dragon Silong polyester version of the CTP system launched by Corey, the price of the whole machine is less than 200,000 yuan, which will greatly reduce the threshold for domestic enterprises to apply CTP technology. But these three CTP equipments are provided by High Water Company in the UK. Hangzhou Corey and High Water are long-term partners.
However, in Print China 2007, Leiba CTP equipment brought by Hangzhou Corey is a CTP product with independent intellectual property rights. "Our goal is to make the price of CTP equipment directly reach a reasonable level. Everyone knows that CTP technology is good, but if the company can't afford it, it can't be used. Even the best technology is in vain. We also fully considered this, Therefore, when formulating product prices, only a reasonable profit rate is pursued, not profiteering. "Indeed, together with the automatic loading device, on-line flushing device and workflow software, the overall quotation of a Leiba CTP system is only 50 Over 10,000 yuan, such a price makes domestic equipment competitive with foreign equipment. At Print China 2007, the heads of many well-known international CTP equipment manufacturing companies came to the Hangzhou Kelei booth. The content of exploring business intelligence was obviously more than the interest in the equipment itself. And these foreign companies really felt the competitive pressure brought by Chinese companies this time.
The first one was installed in Shandong on June 18, 2007. More than 20 units have been ordered in the two or three months since the start of accepting orders. The current Cray CTP price is around 550,000 yuan. The price is less than half of the import. And can already achieve mass production. According to his sales manager Mr. Xu Haijun, it is expected that its sales volume in the CTP market will reach 100-150 units in 2008. Leiba CTP system is completely independently developed by Hangzhou Kelei. Before the development and production of CTP equipment, Hangzhou Kelei was one of the major manufacturers of laser phototypesetters in China. It should be said that for the mastery of laser imaging technology, Hangzhou Corey did not start from scratch. But from film imaging to printing plate direct imaging, the difference between them is still very large. The main technical difficulties are first reflected in the design of the laser and optical path. When choosing the imaging method, Hangzhou Corey also thought about it. They finally chose the 32-channel optical fiber close-pack imaging system. "Lei Pa CTP is a thermal system. This CTP system requires very high laser energy. To ensure the plate-making speed of the equipment, we must ensure that there is sufficient exposure energy. After repeated testing, we finally chose the fiber optic density. Row imaging system. Our fiber optic dense imaging system is not GLV technology, but a fiber corresponds to a laser, 32 lasers have 32 lasers. Our laser and fiber system are from the top manufacturers in the United States, and the quality is very stable. Let customers rest assured that we also provide a 3-year warranty on these key components. "
The difference between Hangzhou Klei optical fiber close-pack imaging system and GLV technology. As mentioned earlier, the optical fiber close-pack imaging system is generally understood as GLV technology. But in fact, GLV technology is only one form of optical fiber close-packed technology. The biggest feature of GLV technology is that a laser beam can be evenly divided into multiple beams, that is, a single laser generator can achieve the effect that multiple sets of laser generators can achieve before. But this technology also has a certain problem, that is, the requirements for the laser generator are very high, because after the light is dispersed into multiple beams, the energy of each beam is reduced. In this case, if the printing plate is to be imaged, the rotation speed of the imaging drum needs to be lowered. The temperature-sensitive CTP equipment using GLV technology, the plate-making speed will not be very high, this is caused by the characteristics of GLV technology itself. The optical fiber close-packing technology selected by Hangzhou Kelei adopts a point-to-point method. Each laser generator corresponds to an optical fiber, and there is no loss of light in the transmission process. Therefore, the imaging drum of the Leiba CTP system of Hangzhou Corey has a higher running speed and a faster plate making speed.
Another difficulty in CTP equipment manufacturing is the imaging drum. CTP technology uses direct imaging on the printing plate. In terms of weight, the aluminum-based printing plate is heavier than the film, and the external drum imaging method is also used. It is much more difficult to solve the dynamic balance problem when the drum system is running. At the same time, the printing plate is not as soft as the film, and positioning is also a problem that needs to be solved. At present, people's requirements for CTP equipment are not only able to directly make plates, but people also hope that one plate making machine can meet the plate making needs of multiple devices at the same time. This variable format demand further increases the difficulty of manufacturing CTP equipment .
In order to make better use of the working efficiency of CTP plate-making machine, Hangzhou Corey also independently developed an automatic plate-making system. Although this loading platform is simple and inconspicuous, it truly realizes fully automatic loading and can automatically remove the backing paper. In terms of function, this boarding station is the same as those of the fully-automatic version box system in foreign countries, and it is the first in China. "In addition, Hangzhou Klein has also cooperated with other companies to develop an on-line printing device, which further improves the efficiency of Leiba CTP system.
Reiz Thermal CTP
It is also a Reiz produced by the rising star of the domestic CTP, Tian Rui Jingyi, whose price is around 600,000. Did not participate in PrintExpo 2007. The first one was sold and installed in 2006, and is used as an internship for students in the teaching and research room of Beijing Printing Institute. The second station afterwards was settled in Xinfeng Printing Factory, which is cooperating with the production work of the enterprise. As of the end of last year, the sales orders in 2007 were around 10 units.
Tianrui Jingyi was jointly invested by Tianbaolite Technology Co., Ltd. and Beijing Jiameng Ruipu Technology Development Co., Ltd. in 2005. Both of these enterprises have a high reputation in the industry, the former of which has a relatively high reputation. The prepress system agents with market share have rich sales experience and professional service system; the latter has unique advantages in high-end networking of electrical extensions and the development of prepress application software. Before the cooperation between the two parties, the two companies have been developing CTP. Until the end of 2005, Tianrui Precision Instrument Co., Ltd. was established, and its internal core department was composed of personnel from the Beijing Printing Institute. The main task was to carefully create the "Reiz Risetter" series CTP plate-making system. Each echelon is responsible for exclusive work, forming a complete R & D, market and service system around Reiz CTP.
At the 2006 All-India Exhibition in Shanghai, Tianrui Precision Instrument CTP made its debut for the first time and attracted extensive attention from exhibiting companies.
The first user of Reiz is listed as one of the key development enterprises in the 11th Five-Year Plan of Beijing Printing Industry-Beijing Xinfeng Printing Factory. The beginning of the cooperation stems from the long-term and friendly cooperation foundation and good reputation before the birth of CTP. This equipment was exhibited at the exhibition. Mr. Gu said very frankly that when we started the installation of Xinfeng, everyone's original intention was to keep on exposing problems and testing. Under the gradual improvement and good use, the second Reiz has settled in the practice center of Beijing Printing Institute for the purpose of training students. The installation requirements of the two Reiz CTPs are different, but so far the installation results have been different-the publication quality is stable.
Reiz CTP also faces the inevitable embarrassment of domestic machines. Reiz constantly finds problems and troubleshoots them, making them more confident about their CTP. In fact, before the official launch of Reiz, it has passed three or four years of repeated improvement time. At present, the major components and key parts of Reiz CTP are still the same suppliers as internationally renowned CTP manufacturers, such as lasers, guide screws, and electronic control parts, all from major international manufacturers. Non-essential spare parts are also manufactured by large domestic manufacturers. As a result, the threshold for enterprises to introduce CTP is greatly reduced for purchasing enterprises, and the cost of using CTP is also greatly reduced.
Since the Shanghai All India Exhibition in June 2006, Reiz CTP has already sold 8 sets.
CTcP of Ryoma Group
There is no doubt that CTP has a faster advantage. But looking at the manufacturers that have introduced CTP, CTF still dominates the actual production and publication statistics. Knowing from the printing company, CTP is still just an embodiment of a better service for the enterprise and a faster supplement. The appearance of CTcP has once again attracted everyone's attention. At present, the number of domestic CTcP installations is about 50, and the price is more than 1.4 million yuan. Due to the different imaging principles of CTcP and CTP, CTcP will have disadvantages in platemaking speed. Normally imported CTP with stable plate-making has a plate-making speed of about 20 sheets per hour, while CTcP will be reduced to 9-12 sheets. At the same time, in terms of the degree of cooperation of the software, because CTcP has not yet fully opened the market, there is relatively little matching software, so the lack of more matching software is also the same. At present, CTcP cannot cause greater CTP The impact of the bottleneck problem.
At PrintExpo 2007, Longma Group, whose leading product is PS plates, launched its first device, CTdP, during the exhibition. According to its technical staff, the core part of this CTdP is still CTP, which belongs to the German equipment imported by the agent; and as far as the entire system is concerned, the processing machine and the upper plate device at the back end of the system are produced by domestic manufacturers The system price is between 2 million and 3 million. Its competitive advantage is that Ryoma has developed unique plates for this set of equipment at a price lower than the price of CTP plates currently on the market. Ryoma added this system according to its "Dragon" English abbreviation d, and became CTdP.
Leopard's CTP
As early as 1998, Baochi acquired the shares of Zhongtianlong Company in "Tianlong Founder" and formed Leopard Founder. With this as its symbol, Leopard entered the CTP plate market. Cheng Kangying, general manager of Leopard Chi, found in his conversation with the customer that the customer's attention to the price of CTP plate material even exceeded that of the CTP equipment itself. "It's easy to proxy CTP equipment, but first we must break through the plate material bottleneck." Considering the unfamiliarity with the CTP plate market, Baochi found a partner, Founder, and invested heavily to start the development of CTP plates. After a full 4 years of hard work, in March 2002, Baochi Founder's negative thermal CTP plate material was officially released. At present, Leopard Founder has successfully developed a positive-heat-free CTP plate without preheating, and is working on the development of a patented no-rinse ultra-thin thermal CTP plate. "According to our understanding, there is no domestic manufacturer that is currently working on the development of such plates." Cheng Kangying said proudly.
Baochi chose Founder as a partner to enter the CTP market. On the one hand, it depends on China's leading level and overall corporate strength in the pre-press field. After several years of intensive research, Baochi Founder Group has successively obtained three technical patents, breaking through the monopoly position of CTP abroad.
Those who are familiar with CTP plate materials know that the key ingredient "dye" in CTP photoresist is very expensive, while the thermally positive CTP plate developed by Leopard Founder at the end of 2003, the main components of the photoresist are all Developed by the research staff of Baochi Founder, the cost has been reduced a lot. At the same time, the difference between the newly developed thermal CTP plate and other similar products is that in the plate coating process, the coating has been temporarily Cross-linked, the entire coating is insoluble in the developer before being scanned by the laser. After laser scanning, the scanned part is soluble in the developing solution, and the unscanned part is insoluble in the developing solution. Therefore, the thermal positive plate material developed by Baochi Founder has very good alkali resistance, high printing resistance, and good dot reducibility, and because the development cost of Baochi Founder is very low, it can be given to users for free. All self-produced intellectual property rights are the biggest advantage of Baochi Founder, and it also makes it possible for households to have the best cost-effective plate materials.
Now Founder also has CTP equipment with independent intellectual property rights, plus the CTP equipment developed by itself. It can be said that the CTP system with two wings flying together is more competitive.
In the CTP market that is in contention, China's CTP equipment will one day occupy the main channel.
