Screen printing originated in our country to print. As early as in the Qin and Han dynasties 2000 years ago, there was a method of printing and dyeing batik, and during the Sui Dynasty, there was a process in which the silk screen was stretched over the frame to be printed, becoming the earliest screen printing technique. China's modern screen printing is an emerging technology that has been continuously developed with the reform and opening up in the 1980s. Its printing materials include: metals, plastics, ceramics, glass, paper, fabrics, and regardless of plane, surface, thickness can be screen printing, so people call it "universal" printing technology. Screen printing has a wide range of applications and can be used for printing in many industries such as light industry, electronics, machinery, automobiles, textiles, chemicals, commerce, fine arts, advertising, architecture, packaging, and many other industries. In decorative products. The beautification of people’s lives, commercial advertising, and electronics industry technologies have played a role that cannot be replaced by other printing methods. At present, screen printing has developed into a relatively complete industrial system. Screen printing and printing are both at home and abroad. Convex and concave printing is one of the four printing methods.
I. International Screen Printing Technology and Economic Market
The international screen printing industry has developed rapidly with the development of photolithography technology since the early 1940s. In the 1960s, due to the emergence of emerging industries and a large number of high-tech products, it also promoted the full development of screen printing technology, professional materials and equipment, enabling it to develop rapidly. In the 1970s, due to the further development and application of screen and photo-sensitive plate materials, the world's screen printing industry also made a leap. Since the 1980s, the characteristics of the development of the international network printing industry: First, the proportion of screen printing in the entire printing industry is increasing; second, the field of screen printing is getting wider and wider; third is the wide range of screen printing and printing The use of computer technology; Fourth, screen printing machinery to automation, materials to many varieties of high-quality direction.
In the world today, the printing industry in Europe, the United States, and Japan is more developed. In the late 1980s, the development of online printing was rapid. There were about 5,000 companies engaged in screen printing, with an annual output value of 3 billion US dollars, accounting for 10% of the total output value of the US printing industry. %about. The output value of screen printing in Japan accounts for about 15% of the total output value of the printing industry, with an annual growth rate of about 10%; France's Dolby Ink Factory, Italy Wanlinglong Sublimation Series Factory, Sweden's Sivia Screen Printing Machine Factory, Swiss Saifa Screen Manufacturing Co., Ltd., German Screen Printing Machine Manufacturing Co., Ltd. and Murakami Screen Co., Ltd. (producing photosensitive materials) are all world-famous manufacturers of screen printing equipment and materials.
In recent years, the development of the screen printing industry in Southeast Asia and Hong Kong and Taiwan has also attracted attention. China's Taiwanese screen printing has taken up a significant proportion in the printing industry. According to relevant information, Taiwan's printing industry has 12% screen printing, 75% offset printing, 11% relief printing, and 2% gravure printing. There are about 240 companies engaged in screen printing equipment production and supply, and about 400 companies engaged in screen printing processing services. There are about 1,000 companies and companies engaged in screen printing in Hong Kong, mainly accounting for about 150 to 200 electronics companies. Others are the textile, garment and card industries.
In the past decade or so, international screen-printing technology and equipment materials have been updated faster than people expected. The new products and information provided at the European FESPA International Screen Printing Exhibition 1999 and the US SGIA International Screen Printing Exhibition in 1999 showed that the computer prepress processing system, color desktop publishing system, and digital computer plate making. Electronic imaging and other technologies have been widely introduced into the screen printing industry. The application of screen printing technology has also been extended to silk screen printing and combination printing. Large-format screen printing thermal transfer, electrostatic printing and other fields. This thermal transfer technology has been applied to outdoor advertising, posters, signs, flower paper, textile and other industries. This development trend has brought new vitality and a broad economic market for the screen printing industry. Nowadays, the electronic circuit boards in Japan are all made using computer technology. The Imperial ink factory in Japan uses computer control from the production process to the operation and management. In Europe, equipment materials, large-scale rotary screen printers, and multi-color screen-printed linkages programmed by microcomputers have been used in screen printing companies. Water-based UV photocurable ink series. High mesh mesh. High-resolution photosensitive adhesives (films) have been commonly used. It is worth noting that some countries with relatively advanced technologies are becoming increasingly saturated. Some countries, such as the United States, Japan, and Italy, are looking for partners in China and establishing "three-funded" enterprises and distribution agents. This is conducive to accelerating the development of China's screen printing industry. We should seize the opportunity.
Second, the status quo and development of domestic screen printing
In the new form of China's reform and opening up, the screen printing industry has made great progress since the Ninth Five-Year Plan. It has a wide range of printing. Thick ink layer. Bright color. The advantages of simple technology, low investment and quick results have been recognized and adopted by more and more industries and fields. Although it has a relatively small proportion compared with plain, convex, and gravure printing, it has not been comparable to flat, convex and gravure printing since the 1980s. The growth rate is 8 to 10%, while the annual growth rate in China is more than 15%.
(1) The area of ​​screen printing continues to expand, and manufacturers and personnel are rapidly growing.
Since the reform and opening up, China's screen printing technology has developed most rapidly in the southeastern coastal areas. Influenced by the development of the screen printing industry in Hong Kong and Taiwan, Guangdong Province started off as the first step, and then extended to Jiangsu, Zhejiang, Shanghai, Anhui, and Beijing. Some of these companies rely on the advantages of taking the lead and relying on regional and financial advantages. They have introduced some foreign advanced technologies and equipment through fund-raising and attracting foreign capital. They have strong technical force, certain advantages and strong competitiveness, and are the industry's leaders. It is a backbone team that develops the screen printing industry in China. Some township enterprises and individual enterprises have also emerged. It is developing from the coast to the interior, from the south to the north, from the east to the west. Jinan, Shijiazhuang, Zhengzhou, and Taiyuan are the leading silk screen printing markets in Shanxi, Hebei, Shandong and Henan provinces. They have been developed and are infiltrating into various industries. Central and southern provinces such as Hunan, Hubei, Chongqing and Hebei, which are centered on Hubei, are becoming popular. Shaanxi, Fujian, Chongqing and Chongqing are developing. Cities such as Dalian, Shenyang, Harbin, Qiqihar and Daqing in Northeast China are driving the development of the screen printing industry in Northeast China. Northwest and southwestern provinces are emerging. Many township enterprises and state-run printing factories in various regions have launched a number of equipment, materials companies, and screen printing plants. They are forming a development base for the screen printing industry. According to incomplete statistics, there are already 10 000 screen printing companies across the country, of which more than 30,000 have begun to take shape. There are more than 250,000 employees registered for industry and commerce. From the perspective of scale and distribution ratio, large, medium and small enterprises are generally 1:4:5; Guangdong's southeast coast accounts for 40%, Jiangsu, Zhejiang and Shanghai account for 30%, northern market accounts for 20%, and other regions account for 10%.
With the continuous increase in the number of screen printer manufacturers and practitioners, the number of screen printing operators has also increased sharply. The fastest growing companies are Sino-foreign joint venture companies and foreign product agents. They have a certain scale and strength. Some domestic backbone equipment manufacturers have also established distribution and sales outlets throughout the country and formed their own sales networks. According to incomplete statistics, the nationwide screen printing equipment distributors (including foreign-funded enterprises) have already reached a scale of about 500, with about 5,000 practitioners, mostly concentrated in the southeastern coastal areas and Beijing, Tianjin, Shanghai and some provincial capitals. Big city. There are already 24 printing material companies from various provinces and cities that have begun to operate screen printing equipment and equipment.
(B) Screen Printing Equipment and Materials and Printing Development
1. Equipment - The number of manufacturers engaged in the development, manufacture and production of screen printing machinery equipment has increased rapidly. Currently, there are nearly 200 screen printing machine manufacturers in China, which have begun to take shape and form a certain production capacity of more than 40 employees with 6,000 employees. In 1999, the production volume was approximately 5,000 units (excluding manual platforms). Sales of 200 million yuan, 150 million yuan in the purchase of imported machines. Generally distributed in Guangdong, Shanghai, Beijing, Jiangsu, Zhejiang, Fujian and Hebei provinces and cities. There are more than 40 product varieties, including pneumatic and semi-automatic. Three-quarters of automatic, fully automatic, monochrome and multicolor, flat and curved machines. Judging from the model, there are many domestic screen printing machines, and there are also pneumatic lifting and pulling. Platemaking equipment basic support, including manual. Pneumatic, automatic stretching machine, a variety of models of dryers, various light sources and different specifications and models of Shai Banji, etc., can basically meet the needs of domestic screen printing. Domestic large-format 2m×4m screen printers and large-scale projection printers have been installed and are welcomed by large-format advertising companies. Peripheral equipment, such as pad printers, heat transfer machines, and trademark machines, are quite numerous, and their output and quality are constantly increasing.
2, ink - screen printing ink from scratch, from less to more. At present, there are more than 100 domestic manufacturers of screen printing inks, 30 of which have begun to take shape, and about 130 kinds of production products (including printing pastes and special screen printing inks such as luminous, fluorescent, and reflective etching), with about 5,000 employees. In 1999, the output was 15,000 tons, and the output value was about 300 million yuan. Four-color ink. UV inks, electronic industrial printing materials, etc. still rely on imports. In 1999, the sales volume of imported ink was about 250 million yuan. The domestic production of spot color screen printing ink, plastic screen printing ink is welcomed by domestic screen printing manufacturers. In recent years, our country has accelerated the development of UV inks. At present, UV printing paper inks developed by Tianjin Ink Company and UV ink printing inks developed by Wuxi Husong Ink Factory have been put on the market. Compared with solvent-based inks, water-based screen printing inks are non-toxic, odorless, non-polluting and meet the requirements of the national environmental protection law. The research and development of water-based screen printing inks has attracted the attention of screen printing material companies and screen printing processing companies.
3, screen - China's low-grade screen has been able to meet the current domestic market needs. With the development of the screen printing industry, the demand for screens is increasing and the quality requirements are higher. In the early 1990s, the Shanghai screen factory produced 300 mesh polyester monofilament plain weave screens by introducing advanced equipment and raw materials, which met the domestic needs. There are also more than 30 companies in Jiangsu Wuxi, Zhenjiang, Suzhou, Taicang, Zhangjiagang, Zhejiang Huangyan, Xiaoshan, Tiantai, Wenzhou, Zhangzhou and Henan, Hebei and other places are also engaged in the production of nylon, polyester mesh, there are a variety of specifications. The annual production capacity is about 15 million square meters, 80% of which are in the low-to-medium range and can basically meet the needs of the domestic market. China's production of wire mesh has few specifications, and its quality has not yet reached the technical level of similar foreign products. More than 300 meshes of nylon, polyester, and stainless steel meshes are imported annually, with annual sales of 180 million yuan.
Several major factors affecting the development of our country's silk screen: First, China's screen printing production started late; Second, it is restricted by imports of raw materials and special equipment; Third, technical equipment is relatively backward, so the product specifications are small, high density, high strength, low elongation silk Mesh, antistatic wire mesh, calendered mesh, nickel-plated wire mesh and other specially treated meshes still need to be developed; Fourth, lack of technical research, quality testing methods still need improvement, quality supervision and arbitration institutions vacancies; The network production enterprises are scattered and the quality of products varies. The use units lack the means of measurement, control, and inspection. In recent years, with the rapid development of the screen printing industry and the surge in the demand for wire mesh screens, wire mesh companies across the country have started production. With the implementation of the national quality standards and production license systems, poor quality screens have flown into the market. There have even been some fake and shoddy products that have caused damage to users.
4. Photosensitive adhesive—The development and production of photosensitive materials is relatively fast. At present, there are 50 photosensitive material manufacturers in China, 10 of which have begun to take shape, and employ about 2,000 people. The annual output is about 2,500 tons, and the sales amount is 200 million yuan. Basically meet the needs of the domestic market, some sold to the Southeast Asian market. Domestic diazo film printing photosensitive adhesive, developed in 1984 and put on the market. DS series diazo photosensitive adhesive produced by Beijing Taipingqiao Printing Material Factory, SF series diazo photosensitive adhesive produced by Zhejiang Jiangshan Chemical Coating Factory, and water and solvent resistance produced by Wuxi Chemical Research and Design Institute and Wuxi Paper Products Factory. Nitrogen photo-sensitive adhesive with excellent performance, is widely used in plastics, paper, signs, metals, glass, ceramics, instruments, leather, enamel, textile printing and dyeing and other industries, is currently the ideal screen sensitive adhesive. The non-diazo SBQ single liquid type photosensitive adhesive and SP type series photosensitive adhesive produced by Beijing Murakami Screen Co., Ltd. are sold nationwide and in Southeast Asia and Europe. It is an ideal photosensitive adhesive for producing high-precision circuit boards, and is also the future development direction. The annual output of film made by film is about 30,000 square meters, and the sales amount is about 750,000 yuan. At present, some high-precision screen printing companies and flower paper, electronic screen printing
