The development status and trend of CTP technology
1. See the development trend of CTP from Drupa
Since 2007, CTP has begun to install large capacity in China, but in the European market, it has been a very mature technology, reaching more than 90% of the installed capacity. Therefore, unlike China's exhibition, CTP is no longer the protagonist at Drupa 2008. However, according to the domestic development situation, we still summarize some of the CTP products on Drupa. The following six aspects will explain the future CTP development direction.
Start the battle of environmental protection supplies
Environmental protection has become the responsibility and obligation of human beings, and this time in Druba, environmental protection plates have become a trump card played by many manufacturers.
Agfa
Agfa launched a number of environmentally friendly chemical-free CTP plates at the drupa, including the thermal plate Green Star: azurats and the purple laser plate: aspire. Green Star Edition: azurats is: azura's upgraded product. Upgraded: azurats can significantly increase the production capacity of each heat-sensitive plate-making machine by combining a glue cleaning unit and a more sensitive coating. : aspire is a chemical-free plate produced by Agfa this time for the purple laser CTP. Violet laser CTP has gradually entered the market in the past two years because of its low energy consumption. The introduction of chemical-free plate materials has increased the environmental protection of the purple laser CTP and will further promote the development of the purple laser CTP technology.
Fujifilm
Fujifilm demonstrated the environmentally friendly chemical-free purple laser version of the brilliant HD pro-v at this year's drupa, and it also showed the brilliant HD series of thermal-free processing materials at its booth.
Chengdu New Map
The most worth mentioning is that Chengdu Xintu Company, which went to the exhibition in China, exhibited a fit eco non-preheated physical environmental protection thermal negative CTP version. The reason why it is called physical environmental protection is because many chemical-free plates still need to be glued or washed at the end of the production process, and this plate also completely eliminates these two processes, and does not produce any waste liquid in the entire plate-making process. .
Kodak
Kodak also exhibited an environmentally friendly thermal direct printing plate without preheating positive plate technology.
Speed ​​to a higher level
Speaking of the speed of plate making, Kodak is the star of Drupa's CTP. Kodak introduced the fastest magnus 800 plate-making machine for the newspaper industry at this year's drupa-capable of producing 60 8-open plates per hour. It uses a brand-new thermal imaging head, which can increase the laser emission power to twice the original. When processing Kodak thermal direct processing-free plates, the speed of magnus 800z can reach 35 plates / hour.
Highlights of power saving
ECRM CTP has always been a model of energy saving and consumption reduction. At this year's drupa, ECRM launched the new purple laser CTP plate-making machine MAKO CTP, whose energy consumption is only equivalent to three 100w bulbs. For some commercial printing companies, using an ECRM plate-making machine can save more than $ 1,000 in energy consumption per year.

Inkjet CTP-the emerging darling of plate making
In this drupa, inkjet plate making has also become a fashion. Jetplate Systems demonstrated the iseter series products on site. The jetplate CTP system is developed on the basis of the epson stylus color 3000 inkjet printer. It improves the transmission device so that the positioning accuracy of the printing plate reaches ± 0.05mm, and is printed on the printing plate with a special plate-making ink called liquid light. Graphic, this plate-making ink chemically reacts with the coating applied to the aluminum plate base to be fixed on the aluminum plate. After development, the non-graphic part of the coating is removed, and then the plate fixing process is obtained to be used. Machine-printed printing plate. The imaging resolution of the jetplate CTP system is 2880dpi, which is equivalent to 175 lines / inch. It can print 15 editions per hour. After two baking editions, the printing resistance can reach 100,000 impressions.
In addition, British FFEI company and Indian technova company both showed inkjet CTP plates in their booths.
Chinese independent brand CTP unveiled at Drupa
At this year's drupa, China has a number of independent brand CTP debut. Corey Laser demonstrated the "Lei Pa" CTP system available for its chemical-free plates with independent intellectual property rights, Founder showed its "Diaolong" purple laser CTP, and Huaguang Precision also showed the latest CTP products.

Bigger, faster and more environmentally friendly
Heidelberg is the world's largest manufacturer of complete printing equipment and the only manufacturer that provides customers with a full range of printing solutions. A new version of Speedmaster CTP was launched on Druba this year, and its largest format is Speedmaster 162. The new generation of Speedmaster CTP has greater production capacity, more flexible operation, and is equipped with many new functional modules. The new laser diode used has increased its power by nearly 60%, and its maximum plate-making speed can reach 38 sheets per hour. [next]
2. In 2008, China's CTP equipment was mixed
At the 11th International Printing Information Exchange Conference, the latest set of data on China's CTP (Computer Direct Platemaking) status quo statistics: As of September 2008, China's total CTP installed capacity was nearly 1,500, and the total amount of CTP plates used It is 10 million square meters, and the average plate-making volume of each machine is 14,400, and the average daily publication volume of each machine is 48. Looking into the data, we can see that the current status of CTP application in China is mixed. The good news is that this year's CTP has grown steadily compared to last year, but it has not ushered in the expected "explosion growth", and the actual application effect is not good.
Low penetration rate and low operating efficiency
It is understood that the total number of 1500 sets of this data also includes CTP equipment for testing, demonstration, and teaching. Except for the proportion of these non-commercial uses, it is also necessary to consider the final results affected by the discrepancy of statistical data. According to the estimate of Xiang Jianlong, chairman of Hangzhou Kelei Electromechanical Industry Co., Ltd., in fact, there are currently 1200 CTP equipment in China in normal operation. For an average of 48 publications per machine per day, "this data is relatively low," Xiang Jianlong said at the current International Printing Information Exchange Conference. He said: "For a standard commercial CTP, 20 plates per hour is a standard data. It is conservatively estimated that if a printing factory calculates with the workload of an 8-hour work shift every day, a CTP device There are at least 160 copies of plate making. "
Therefore, Xiang Jianlong summed up the current status of China's CTP application: "CTP equipment has a very low operating efficiency, and China's use is still quite backward. Many CTPs only exist as concept machines; they have not reached the actual application stage. The existing CTPs on the market if With normal use, the production capacity will be doubled. "The CTP ownership of 1500 sets is only about 1.5% of the 100,000 printing enterprises in China, which is far from the developed countries.
According to reports, in 2006 the penetration rate of CTP in the United States reached about 75%, 70% in Europe, and 50% in Japan. China's CTP penetration rate is low, operating efficiency is low, and the application area is narrow. In addition to the high price of the plate material, which is the main factor affecting the CTP utilization rate, there is also a mismatch between the business volume of the installed enterprise and the production capacity, and the application technology is not mature The lack of technical talents and other reasons.
Large demand gap in the next five years
According to speculation by relevant experts, China ’s CTP penetration rate will reach 70% after 5 years. In terms of plate usage, there will be 60 million square meters of printing plates to be transformed into CTP plates in the next 5 years, and how many units will be needed by then The CTP equipment industry is also difficult to conclude. According to Xiang Jianlong's calculation plan, if it is based on the current 48-unit CTP application, about 7000 CTPs are required, and if it is calculated according to the normal 160-unit CTP capacity standard, only about 2,000 CTPs are required. Others argued that there will be 10,000 CTPs in China in 10 years. In addition, some people have proposed to realize the utilization rate of “one factory and one unitâ€. Decide.
When CTP is fully developed in China, what percentage of each type of CTP will occupy, which technology will become the leader? As of September this year, the CTP equipment of the three mainstream technology types of thermal, photosensitive, and PS plate-making directly accounted for 63.59%, 28.30%, and 6.35% of the total holdings, respectively. From these data, thermal CTP occupies the top of the list, photosensitive CTP also has a large market advantage, and the market share of the PS version of the direct plate is not enough to have a great influence.
Some insiders said that various technologies have their own advantages. Thermal and photosensitive technologies have developed and matured, while the PS plate-making technology has become a "dark horse" in the CTP arena, opening up more opportunities for CTP applications. A wide range of new fields.
Plate prices become a bottleneck restricting development
Faced with the technical disputes between these three, Xiang Jianlong's personal view is that the CTP directly made by the PS version is the real CTP, because the original intention of the CTP concept is to transition from CTF to CTP and cancel the film.
The promotion of PS plate-making directly is mainly restricted by the three major problems of equipment cost, plate-making speed and plate-making quality. Xiang Jianlong believes that with the rapid promotion of purple laser technology in the civilian field and solving the light source problem, the speed of plate making and the quality of plate making have been greatly improved, and it has reached the standard of ordinary CTP; For small and medium-sized enterprises that operate printing presses, 40,000 sheets per year are used as the standard. If traditional PS plate-making technology is adopted, the cost of the film can be saved directly, and one million yuan can be saved in one year. Will be very attractive to customers.
However, Teng Fangqian, director of the second glue factory of Lucky Group, said that at present, there are not too many domestic PS version production lines changed to CTP production lines, because the conventional PS version can be compatible with small batch jobs, only when mass production Only need to transform or build a new special production line. Therefore, whether the direct plate-making technology of the PS version can suddenly emerge and dominate the CTP cannot be clearly stated. Everything still has to be verified by the market and practice. The emphasis on the cultivation of professional technical personnel, etc., the comprehensive upgrade of China's pre-press industry and the popularization and application of CTP and digital processes will certainly be realized.
