Bird bath are mostly made of porcelain, because apart from pecking at rice, bird bath are more convenient for birds to drink, so porcelain bird bath are the most suitable materials for all. Because the ceramic is heavy, it is not easy for birds to turn over when they step on it. It is better to find wide than high.
The first is to establish a complete and efficient digital process. For instance, Yangcheng Evening News used 6 AG-FA CTP platesetters to achieve a fully digital workflow and become a model for printing in the national newspaper industry. The China Business Printing Company in Shenzhen used three Creo CTP platesetters to achieve a full digital flow of books and beautiful pictures.
The second is to simplify the process and shorten the production cycle. CTP technology eliminates the need for film, printing, and rinsing processes in traditional platemaking methods, reducing human error, improving the quality of printing plates, and providing high resolution, strong network points, and accurate positioning. For instance, the Yangcheng Evening News reduced the number of people in the traditional plate making process by 60. The deadline for writing each day was delayed by 40 minutes, which greatly improved the timeliness of newspapers.
The third is to greatly expand the scope of business. Adopting CTP technology not only improves the quality of conventional printing products, because it uses broadband network transmission and can accept customer electronic files, which greatly expands the business scope. China Business Printing Company is an excellent example.
Fourth, due to the increasing maturity of digital proofing technology, digital proofs have been recognized and praised by customers.
Achieving a fully digital workflow signifies that the printing industry is moving toward the information age. It is not only a technological revolution, but also a change of management mode and business model. The promotion and application of CTP technology is the core of the digital workflow.
In general, although Guangdong Province has a leading position in the application of CTP technology in the country, it is speculated that the CTP still has a large room for growth in China. The total output value of the printing industry in Guangdong Province accounts for about one-third of the country's total output value, but its CTP holdings account for 57% of the country's total. This shows that there is still much room for the promotion of CTP in other provinces; and CTP is also far from Guangdong. It has not reached the level of popularity, but the installed capacity of CTP in China accounts for only 2% of the total CTP installed capacity in the world, which shows that CTP still has great potential for growth in China.
The advanced nature of CTP technology is undoubted, but why is it not yet fully popular? The main technical hurdles are:
One is that the plates are expensive. The plates used by Guangdong's printing companies that use CTP are AGFA's silver salt version and KPG's thermal plate, and a small amount of two-ply thermal plates. For example, Yangcheng Evening News has used AGFA's silver salt version for approximately 160,000 square meters a year. Due to the large volume of purchases, AGFA bears half of the import tariffs, and the total amount of each version is 38 yuan, which is 10 yuan more than the ordinary version. However, imported media used by a number of companies have to be around 60 yuan, which is about twice as high as the prices of domestically produced media. Take the newspaper industry as an example, a medium-sized plant with a better CTP technology will consume 5-10 million sheets per year. If 50,000 sheets are used to calculate, if a plate is 20 yuan more expensive than a regular PS plate, the whole year It is necessary to increase the cost of printing materials by 1 million yuan. Printing companies with good economic returns are unbearable, and other printing companies are even more difficult to accept.
The second is that the supporting flushing fluid required by the domestic thermal plate of the Second Glue Factory cannot be used with the KPG rinsing fluid, which brings inconvenience to users.
Third, there are three types of plates: heat-sensitive, silver salts, and photopolymerization. There are also three types of platesetters: platform, outer drum, and inner drum. Although each has its own advantages and disadvantages, it also has users in the country and has accumulated some experience. However, various manufacturers still have great differences on the selection views, which also affects the speed of promotion.
Fourth, the industry lacks communication and information blocking for the application of CTP technology.
CTP has undergone fierce market competition from its inception to development, thus forming the current market structure. How to guide CTP applications to a more reasonable and scientific direction requires a lot of work. We do not advocate a one-on-one approach and do not advocate conservative or exclusive technology. All decisions should be based on the actual production conditions, economic strength, and technological level of each company, but the general trend is rising. To promote the use of CTP on a large scale, localization of plates is imperative. Domestic printing sensitized material manufacturers and scientific research departments should take effective measures to accelerate the research progress and vigorously develop CTP plates and related equipment components.
In addition, we must strengthen information exchange, strengthen media publicity, and promote the popularization and improvement of CTP technology.
Domestic CTP equipment is also working hard for SMEs on the road to CTP, and has achieved initial results. Such as Shenyang Boji Technology Development Co., Ltd. and Beijing Commodity Making Co., Ltd. launched. The inkjet CTP has been adapted to the needs of small and medium-sized printing companies; the CTP equipment developed by Peking University Huatong Co., Ltd. is in line with China's national conditions, and the quality has also been affirmed by users, but there is still a certain gap compared with foreign imported equipment.
In terms of media, KPG, AGFA, and FUJI, three international suppliers of plates, have established factories in China; Henan Dijiao has made breakthroughs in the thermal and silver salt technologies, and is expected to achieve mass production; the Institute of Photosensitive Science and Technology, Chinese Academy of Sciences The Shantou Special Zone Daily reportedly cooperated to build a silver salt production plant in Shantou. Samples have been successfully printed on the Beijing Daily and Evening News; Beijing Normal University and Guangxi Yulin Jinlong PS Plate Printing Materials Co., Ltd. have also produced thermal plates; Shanghai Printing Photopolymer plates developed by the Institute of Technology have also been identified.
The above-mentioned new progress of domestic CTP equipment and plates will break the situation where foreign companies dominate the world, which will undoubtedly further promote the promotion of CTP technology.
