Digitization of printing production is a major trend in the printing industry. In order to meet the needs of market competition, the Yangcheng Evening Newspaper Group has been paying attention to the development of related technologies, actively adopting new technologies and new equipment, and benefiting from it. The Yangcheng Evening Newspaper Group began to use desktop publishing systems and laser phototypesetting systems as early as 1988. With the rapid development of computer technology, the 2000 newspaper office has been able to run newspapers, advertisements, distribution, finance, Office business. Among them, the reporting process was the first to run on the Internet, and the editing process in the computer workshop of the printing plant was changed to the responsibility of the editor. This reform makes the entire process reasonable and smooth, greatly improving the efficiency, and making printing out of the comprehensive development of the newspaper. Foreshadowing. In 1998, the Newspaper Group began to introduce CTP equipment, the purpose is to explore new technologies for the new printing center, so that the future production process can be integrated in the network and orderly controlled, so that the network and new equipment, New technologies better realize their true value in production. In 2001, the new printing center was put into use, and the Group took the lead in using CTP platemaking in China on a large scale, completely abandoning the traditional platemaking process. It has been applied for 3 years so far and has achieved a win-win result in economic and social benefits. New production center with high production capacity The new printing center was planned to be built during the fall of the fierce competition in the newspaper industry. At that time, the overall situation of the competition in the newspaper industry in Guangzhou was basically determined. From 1985 to 1998, although the printing capacity of the printing plant continued to expand, it was far from being able to meet the requirements of expanded layout and advertisements for color layout. More than 30 layouts per day, more than 800,000 copies of color printing, a few units that can print on both sides of the color for more than 20 hours a day still can not be completed on time, can only be sent out for printing or printing in advance, encountered mechanical failures, even worse . Its own shortcomings have caused a passive situation in the advertising market, which has greatly reduced the absorption of advertising. The serious lack of printing capacity and the lag in timeliness of publishing have become the main reasons for the sudden decline in newspaper revenue. Therefore, when the printing capacity of the new printing center is expected to be planned for 10-15 years, the maximum printing capacity is 6 million pairs / hour (full color). At the same time, according to the characteristics of 86% of the newspaper's printing volume, the solution to the outstanding problem of high timeliness is to choose double-format high-speed, two-way newspaper, which not only solves the timeliness but also can use the least staff to exert the highest benefits in 1-2 shifts. After the completion of the new printing center, the equipment of the old factory is reserved for printing on behalf of newspapers and outsourcing. The time period for printing and printing is clearly distinguished to ensure the timeliness of the report, which not only plays the role of the old equipment, but also avoids the additional expenditure of handling and disassembly. Practice has proved that the 1/3 factory building currently used in the printing center has installed three sets of 13 double-width towers, and starts printing "Yangcheng Evening News" in the order of D, C, B, and A from 6:30 a.m. until the afternoon. All the printing was completed at 14:30. In addition, before and after the printing of the Evening News, arrangements were made for the printing of the "Hong Kong Commercial Daily", color layouts, and large-volume advertising special issues. The average printing volume is 8.2 million pairs per day. The equipment runs for 10 hours. Arranging two shifts of staff is relatively easy to complete. At the same time, there is ample time for equipment maintenance. Therefore, there has been no report of aging due to equipment failure in the past three years. phenomenon. After adjusting and adding equipment in the new and old factories, the color printing capacity has been greatly improved, but the staff has not increased, and the benefits have improved significantly. After further business development, you can add equipment to meet your needs at any time, handy. Fully adopt CTP technology to benefit 5 units were installed at the 7 stations in the first phase of the project, and 7 stations were reserved for the second stage. By 2000, the lithographic silver salt plate-making technology was fully mature, and the newspaper decided to fully adopt CTP technology in the plate-making process. After repeated calculations, 3 Polaris 200 models, 2 Polaris 100 models, 3 LINA automatic punching bending machines and conveying lines were equipped, coupled with Peking University "Boheng" management system, forming the largest CTP system in Asia at that time. The production capacity reaches 720 quadruple editions per hour, that is, the number of editions required for 12 printing towers can be produced in one hour, and the speed is quite fast, which is very suitable for the publication requirements of "Yangcheng Evening News" "watch the same day". Three years of production practice has proved that it can be squeezed out for 1 hour in the plate-making process every day, which gives editors a lot of leeway. The amount of information increases that day, which ensures that the readers in Guangzhou see the latest news. Therefore, the A version of the news is always new, and new technology is indispensable. The CTP technology has made the Yangcheng Evening News truly win-win economic and social benefits. Now the CTP technology is more mature and widely used, and the selection range of photosensitive and thermal is larger, which is more conducive to the needs of high quality and high speed development. Using CTP technology, the author believes that it is high cost, high efficiency, high quality, high return, must have viable conditions, urgent needs, and scale, in order to give full play to the superiority of high technology and automation, and then to benefit. [next] Prerequisites for adopting new technology CTP is an important step for the printing industry to enter data. First of all, in the publishing process of newspapers, it is stipulated that journalists, editors, and editor-in-chief on duty all issue and print on the Internet, each with its own authority, operating in accordance with the time limit of the process, and no changes are allowed. The pictures to be used in each page must inform the printing factory of the time of use, specifications, requirements and the page where they are located. According to the printing requirements, after processing, they should be placed on the server library on time for backup. The editorial department must not change and handle it by themselves. Special circumstances require permission from the editor in chief. . Each layout (including advertisements) is divided into line array editions according to each edition. After the group edition, the printing is issued by the chief editor on duty to the printing factory transmission group, and the relevant advertising layouts are connected according to the specifications of the plate core. After approval, it is transmitted to the CTP plate making and printing through the special optical fiber. The four-plate layout is used for plate making. Due to the limitation of the time limit for each plate layout, the plates are separated by about 5 minutes. It is convenient for continuous publishing of CTP equipment, and the printing workshop can publish to the version at any time. It does not need to wait for the adjacent layout to publish. It makes full use of the advantages of automatic continuous publishing and fast punching and bending. After canceling the mid-seam, expand the quadruple plate center to the left and right by 10mm, and the total layout is 5mm larger than the original. Try to use the same specifications of plates and consumables, which requires the continuity of the purchased equipment. For example, the specifications of the blankets used are all 1143mm × 830mm, and the specifications of the 13 printing tower plates of the new factory are all 383mm × 577mm. In this way, the automatic plate-making system can continuously and accurately produce high-speed and accurate features. Of course, a variety of specifications recommended by the equipment supplier are feasible, but the supplier will not consider the impact of the time and accuracy including conversion and adjustment. It is necessary to adjust these aspects frequently, which will inevitably reduce the speed and accuracy. If the use is not smooth, the effect will not be obvious. I feel that it is not as fast as the traditional process. High cost, high efficiency, high quality and high return The cost accounting should consider the comprehensive cost. The new printing center has been accounting for the same amount of production for three years. According to the "Yangcheng Evening News" report process, an average of 40 color editions per day. The advertisement is submitted one day in advance and printed in 4 times. A total of 160 sheets (40 sets) of 4 color films are required, each set for 15 minutes. It takes 10 consecutive hours to print 1408 copies (704 copies), each one minute, a total of more than 11 hours. There are nearly 60 editions 2 days a week, which takes longer. At most, more than 1,700 copies are used daily. According to this calculation, the use of traditional technology requires about 35 people. To meet the requirements of timeliness, 3 to 4 sets of phototypesetting, filming, printing, and imposition equipment must be configured, occupying a large area of ​​space, using necessary auxiliary materials, and using a large amount of electrical energy. At the same time, the labor intensity of workers is high, the probability of errors is large, and quality control is difficult. For the same workload, it takes only 4 to 5 people in a CTP process, one shift, and the printing plate can be produced in 45 minutes per round. Without auxiliary materials, the power consumption is only 1/3 of the traditional process, and the quality is stable. In particular, the overprinting is accurate, the time to start the plate is adjusted, the time for controlling the ink volume is greatly reduced, and the worker works easily. The maximum effect can save an hour for editors to grab news, which plays a decisive role in the evening news. Its economic and social benefits are incalculable. At present, CTP equipment and plate materials are expensive, which is the biggest obstacle to its promotion. Therefore, it must be scaled, continuous production, and can not coexist with traditional processes, otherwise it is definitely high cost. At the same time, equipment failures may occur during use, and it is not difficult for operators to eliminate them in time after they are proficient. After a certain scale is formed, even if an individual machine fails, it will not cause much impact. But the laser head is a key component, and there must be spare parts and frequent inspection, adjustment, and minimize the failure rate. When conditions permit, it is necessary to adopt logistics automation as much as possible, such as automatic ink supply, automatic paper supply, and automatic bundling and distribution system for distribution. This is necessary to improve efficiency, improve technical level, and realize the integration of digital printing with international trends. the road.
