First, the status of home-made sheetfed offset presses In China, offset printing has accounted for about 80%, many printing departments, printing has all offset printing, and, in addition to newspaper printing, in offset printing, sheetfed accounting Most of them. Therefore, the sheet-fed offset press occupies an important position in the printing industry.
China has been producing sheet-fed offset presses since the mid-1960s. After more than 30 years of hard work, sheet-fed offset presses have grown from scratch, from single-species to high-, medium-, and low-grade products of different specifications. From only a few manufacturers can produce them. Sheet-fed offset presses have developed to a considerable number of companies capable of producing offset presses. In recent years, the annual output of four-fold offset presses has reached 1,000 units, and the annual output of offset presses is also over 2,000 units. In addition to the most advanced sheet-fed multicolor offset press, the domestic offset press has been able to meet the needs of China's printing industry. At present, the installed capacity of sheetfed offset presses in China is about 20,000, of which more than 80% are domestic machines.
The performance of domestic sheetfed offset presses already has a high level. In terms of speed, we have been able to produce 15,000 sheets per hour of machinery that has reached the international advanced level. Judging from the printing performance, some domestic offset presses have approached or reached the international advanced level. In terms of automatic control, the world’s most advanced advanced and practical technologies, China has been able to produce most of it and equip our country’s printing industry. A few have already been working on research and will soon meet with users.
Although domestic sheetfed offset presses have made great progress, there are still many gaps from the international advanced level. Mainly in the machine's stability, reliability and automation of intelligent control. In recent years, there are some new technologies that have emerged in the world and we have not mentioned the agenda. Such as digital offset press, ink emulsifier emulsification printing technology, seamless printing roller without shaft drive technology.
Second, at the turn of the century, the domestic sheet-fed offset press will face the development of a knowledge-based economy and the integration of the global economy. At the same time, China will soon join the WTO and accelerate the integration of domestic and foreign markets. Under such circumstances, how to develop a domestic offset press has attracted the attention of colleagues in the printing industry. Entrusted by the Economic and Trade Commission, the China Printing and Equipment and Equipment Industry Association proposed the development guidelines for China's printing industry before 2010. The development direction of printing is “multi-color, high-efficiency”, that is, “promotion and application of one-time printing can print multiple colors. The printing process and high-efficiency equipment will improve the proportion, quality and efficiency of color printing.“In a variety of printing methods, offset printing will still dominate,” “The development focus of printing presses is still multi-color offset printing presses,” Sheet offset press, first of all will be a multi-color offset press to improve the quality and grade on the basis of forming a complete series of products. Proper development of multi-color offset printing presses and multi-color offset printing presses suitable for small-batch printing on demand.
Based on this, I believe that domestic offset printing presses should be developed in accordance with the domestic specific conditions, combined with the development of domestic and foreign technologies and markets.
Sheet-fed offset multi-color offset printing press has a large quantity and a wide range, and should be developed as a key point. First of all, we will form a complete series of products based on the improvement of quality and grade. That is to develop a series of offset presses of high, medium, and low grades that are suitable for market needs and that conform to international standards, from monochrome to multi-color, and can be configured with various functions according to market needs. The medium and high-grade multi-color offset printing machines are the most important ones. According to market demand, properly develop multi-color offset presses and multi-color offset presses suitable for small-lot print on demand. The product performance and quality goals are: Some products are close to or have reached the international advanced level at that time, and general products have reached the mid-range utility, gradually eliminating low-end products.
The focus of the development of sheet-fed multicolor offset presses is to increase the level of automation, digitization and intelligent control. The focus should be on the compression aid time and improve the stability and reliability of the machine to increase the efficiency of practical printing. To this end, it is necessary to first solve the internationally advanced and applicable technologies, domestic technologies that are not yet fully cleared, and that should be developed as soon as possible to make them practical, stable, and reliable. Such as print specifications, automatic dry adjustment, automatic register, print quality and fault display, diagnosis and automatic adjustment, semi-automatic and automatic version. And according to market demand, the development of supporting and auxiliary equipment, such as light, drying and turnover devices.
Our country has been able to produce offset presses with a speed of 15,000 sheets/hour. There is no need to work harder on speeds, because even though speeds may increase further, it will greatly increase manufacturing costs, but it will not necessarily bring greater advantages. At present and for a considerable period of time, it is necessary to concentrate on solving the practical problems that still exist in order to achieve the specified operating speed, so that they can be reliably and reliably achieved. At the same time, the structure and measures for shortening the auxiliary time can be operated stably and reliably. The speed of actual operation has gone up, the auxiliary time has come down, the stability and reliability have been solved, and the user can get the benefit before accepting it. For a large number of mid-range and low-end machines, the actual operating speed should be about 10,000 sheets/hour, and the stability and reliability problems should be solved at the same time. This can lower the cost of the machine, lower the selling price, and benefit both users and manufacturers. For machines with a speed of less than 5,000 sheets/hour, they should be determined to upgrade and renovate their performance and quality so as to meet the needs of market development.
3. Some Suggestions From the perspective of long-term development, with the development of reform and opening up, accession to the WTO, and economic globalization, we will further promote the development of our country's printing industry and offset press technology, and enable our country's printing industry and offset press manufacturing technology. Get closer to and catch up with the world's advanced level faster. However, at present, due to the reduction of tariffs, foreign products will accelerate the occupation of the domestic market, impact the domestic offset press market, and accelerate the reorganization of offset printing companies. After pain and hard work, our country's offset printing manufacturing industry will develop better.
Faced with this situation, what should our company do? Relevant people think that should proceed from the following aspects:
1. Accelerate product structure adjustment Develop mid-range, stable, and low-price products to adapt to market changes. That is to say, firstly stand firm on the mid-range machine and withstand the impact after China's entry into the WTO. At the same time accelerate the development of high-grade multi-color offset press, so that high-performance, high-quality multi-color offset press truly pass. In this regard, there is still a lot of work to be done.
2. Increase investment in science and technology and improve technological innovation capacity The important reason why our product quality, performance, and quality do not go up is that our investment in science and technology is too small and we have not placed scientific research and technological innovation in an important position. For many years, we have mainly depended on others. Learn without own things. Domestic qualified enterprises should concentrate on certain qualified and experienced scientific researchers and create conditions for them to concentrate on conquering new technologies that are advanced and practical and that we have not yet closed, to make them truly stable, Reliable, practical, and on this basis, create their own unique technology.
