Realizing the digitalization of printing production is a major trend in the printing industry. In order to meet the needs of market competition, Yangcheng Evening News 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 News Group began to apply the desktop typesetting system and the laser phototypesetting system as early as 1988. With the rapid development of computer technology, the newspapers in 2000 have been able to run newspapers, advertisements, distribution, finance, etc. on the Internet. Office business. The reporting process was first run on the network, and the grouping process in the computer workshop of the printing factory was changed to the editor's own responsibility. This reform made the whole process reasonable and smooth, greatly improved the efficiency, and made the printing out of the newspaper comprehensive development. Paved.
In 1998, the newspaper group began to introduce CTP equipment, in order to explore new technologies for the new printing center, so that the production process can be integrated into the network and controlled in order to make the network and new equipment, New technologies are better at realizing their true value in production. In 2001, the new printing center was put into use, and the group took the lead in the large-scale use of CTP plate making in China, completely abandoning the traditional plate making process. It has been applied for 3 years now and has achieved a win-win situation in terms of economic and social benefits.
High-capacity new printing center
The new printing center was built in the period of the fierce competition in the newspaper industry. At that time, the overall situation of the Guangzhou newspaper industry was basically fixed. Between 1985 and 1998, although the printing capacity of the printing house was constantly expanding, it was far from being able to adapt to the requirements of the expansion of the layout and the color layout of the advertisement. More than 30 layouts and more than 800,000 copies of color printing per day. A small number of units capable of printing double-sided color can only be completed on time for more than 20 hours per day. It can only be printed on the outside or printed in advance. In case of mechanical failure, it is even worse. . The lack of its own has caused the passive situation of the advertising market, greatly reducing the absorption of advertising, the serious lack of printing capacity and the lag of the release time has become the main reason for the sharp decline in newspaper income. Therefore, the printing capacity of the new printing center is expected to be 10-15 years of planning, the highest 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 problem of high timeliness is to use double-speed high-speed and two-way reporting, which not only solves the aging effect, but also uses the least number of personnel to achieve the highest efficiency in one or two shifts.
After the completion of the new printing center, the old factory equipment is reserved for printing and printing newspapers and newspapers. Clearing the time period of the printing period ensures the timeliness of reporting, which not only plays the role of the old equipment, but also avoids the extra expenses of handling and disassembly.
Practice has proved that at present, one third of the workshops used by the Printing Center have installed three sets of 13 double towers. Every day at 6:30 am, the "Yangcheng Evening News" is printed in the order of D, C, B and A. At 14:30, all the printing was completed. In addition, before and after the printing of the evening news, the Hong Kong Commercial Daily, the color layout and the large-volume advertising special issue were arranged. The average daily printing volume is 8.2 million pairs, the equipment is running for 10 hours, and the second class is arranged. It is relatively easy to complete, and there is also ample time for equipment maintenance. Therefore, there has been no report of aging due to equipment failure for 3 years. phenomenon. New and old factories have been adjusted and added equipment, and the color printing capacity has been greatly improved, but the number of personnel has not increased, and the benefits have been significantly improved. In the future, if the business develops again, you can increase the equipment to adapt to your needs at any time.
Full use of CTP technology to benefit
In the first phase of the project, 7 stations were installed at the first location, and 7 stations in the second phase were reserved. By the year 2000, the lithographic silver salt plate making technology was fully mature, and the newspaper decided to adopt CTP technology completely in the plate making process. After repeated calculations, three Polaris 200 models, two Polaris 100 models, three LINA automatic punching platesetters and conveyor lines were deployed, and the Peking University Boheng management system was formed to form the largest CTP system in Asia at that time. The production capacity reaches 720 four-page editions/hour, that is, the number of editions required for 12 printing towers can be made in one hour, and the speed is quite fast, which is very suitable for the publication requirements of "Yangcheng Evening News" "Looking for the day of the day". The three-year production practice proves that it can be squeezed out for one hour every day in the plate making process, which brings a lot of room for maneuver to the editor. The amount of information on the day increases, ensuring that the readers in Guangzhou are seeing the latest news. Therefore, the A version of the news is always new, new technology is indispensable, CTP technology makes the Yangcheng Evening News truly achieve a win-win situation of economic and social benefits. Nowadays, CTP technology is more mature and widely used, and the selection range of photosensitive and heat sensitive is larger, which is more conducive to the development of high quality and high speed.
Using CTP technology, the author believes that high cost, high efficiency, high quality, high return, must have feasible conditions, urgent needs, scale, in order to give full play to the superiority of high technology and automation, in order to benefit. [next]
Prerequisites for adopting new processes
CTP is an important part of the printing industry's entry into data. First of all, in the newspaper publishing process, it is stipulated that the journalists, editors, and duty editors all run on the network, each has its own authority, and it operates according to the statute of limitations of the process, and may not be changed at will. The pictures to be used in each layout must be notified to the printing factory according to the time, specifications, requirements and layout. According to the printing requirements, after processing, they will be placed on the server library for backup. The editorial department shall not change or handle the procedures themselves. .
Each layout (including advertisements) is formatted in an array according to each edition. After the group version, the seal is issued to the printing company's distribution group by the editor in charge, and the relevant advertisement layout is serialized according to the core specification. After approval, it is transmitted to the printing center CTP plate printing through special optical fiber.
With four-page layout, the versions are separated by about 5 minutes because the process is time-limited for each layout. It is convenient for CTP equipment to be continuously published, and the printing workshop can be printed from time to time. It is not necessary to wait for the adjacent layout to be published, and the advantages of automatic continuous publishing and punching and bending can be fully utilized. After canceling the middle seam, the four-opening version is enlarged by 10mm to the left and right, and the total layout is increased by 5mm.
Try to use the same specifications of plates and consumables, which requires consistency in the purchase of equipment. For example, the specifications of the blankets used are all 1143mm × 830mm, and the specifications of the 13 printing towers of the new factory are all 383mm × 577mm. This enables the automatic plate making system to produce continuously and accurately, and to achieve high speed and accuracy. Of course, the various specifications recommended by the equipment supplier are feasible, but the supplier does not consider the effects of including conversion, adjustment time and accuracy. It is often necessary to adjust these aspects, which will inevitably make the speed and precision greatly reduced. If the use is not smooth, the effect will not be obvious, and there is no traditional process.
High cost, high efficiency, high quality and high return
The costing should consider the comprehensive cost. In the past three years, the new printing center has been producing the same amount of accounting.
According to the report process of "Yangcheng Evening News", an average of 40 color editions per day, the advertisements are delivered one day in advance, divided into 4 prints, and a total of 160 sheets of 40 color films (40 sets) are required, each set of 15 minutes. It takes 10 hours in a row and 1408 sheets (off 704 sheets), each of which takes 1 minute and takes more than 11 hours. There are nearly 60 versions in 2 days a week, which takes longer. At most 1,700 copies per day. According to this calculation, the traditional process requires about 35 people. To meet the aging requirements, it is necessary to configure 3 to 4 sets of photo-discharge, punching, printing, and imposition equipment, occupy a large area of ​​the site, use the necessary auxiliary materials, and use a large amount of electric energy. At the same time, workers have high labor intensity, high probability of error, and difficult quality control. The same workload, the use of CTP process as long as 4 to 5 people, a shift, each round of printing with 45 minutes can be completed, without auxiliary materials, electricity consumption is only 1/3 of the traditional process, quality is stable. In particular, the overprinting is accurate, the time to start the printing, the amount of ink control is greatly reduced, and the workers work easily. The maximum effect can save 1 hour time for the editor to grab the news, and the news of the evening newspaper has played a decisive role. Its economic and social benefits cannot be estimated.
At present, CTP equipment and plates are expensive, which is the biggest obstacle to its promotion. Therefore, it must be scaled up, continuous production, and can not be mixed with traditional processes, otherwise it must be high cost. At the same time, equipment failures may occur during use, and it is not difficult for the operator to be promptly eliminated after being skilled. After a certain scale is formed, even if there is a problem with an individual machine, it will not cause much impact. However, the laser head is a key component and must have spare parts and frequently check, adjust, and minimize the failure rate.
When conditions permit, use logistics automation as much as possible, such as automatic ink supply, automatic paper supply, automatic bundled distribution system for distribution, etc. This is necessary to improve efficiency, improve technical level, and achieve digital integration of printing and international trends. the road.
