Development and Prospect of Screen Printing Industry in the Mainland


The development and prospects of the screen printing industry in the Mainland Overview of the development of the screen printing industry in the Mainland In the fifties, the gap between China's screen printing technology and foreign countries is not large. Has been able to produce their own screen printing machine and some auxiliary equipment. In Beijing, Shanghai and other places, there are professional screen printing factories to undertake various screen printing business. In the early days of the liberation of Shanghai, there was a special printing factory in Shanghai. It was a screen printing professional factory. It is said that this factory also trained many screen printing professionals abroad. For a variety of reasons, only a few screen printing plants have been revoked. Since then, the development of screen printing technology has been slow, not only lagging behind those of Europe, the United States and Japan, but there is still a gap between Hong Kong and Taiwan.

According to the survey, in the 1980s, there were about 100 screen printing and processing plants (including workshops and work teams) in the 1980s, and currently more than 200, with about 1/3 of the Chinese camps, and about 2 collectives and individuals. / 3, employing about 3,000 people, with an annual output value of about 18 million yuan. The screen printing products produced by these manufacturers include: advertisements, paper boxes, enamel decals, glassware, knitwear printing, bed sheets, towels, self-adhesive labels, circuit boards, signs, plastic products, lottery tickets, and thermal transfer printing. Paper, film circuits, soft film buttons, panels, mirror printing, guide printing, souvenirs, etc. In the screen printing equipment industry, Beijing is currently able to produce semi-automatic platform screen printers, multi-function screen printers and large format screen printers of 1.5 x 3 meters. In terms of materials, it has been able to provide the market with photosensitive emulsions, screen printing pastes and various coatings, and screen printing inks. Most of these screen printing equipment manufacturers and their products appeared in the late 80's.

The 1980s, especially in the mid to late 1980s, was an important milestone in the development of mainland modern screen printing. In the area of ​​screen printing, the diazonium sensitive photoresist developed by the Beijing Institute of Printing Technology in 1984 was put on the market. This led to a change in the traditional screen printing method in the Mainland, and the hand-made plate of the laminating film was sensitized. The plate-making method was replaced, and the toxic dichromate ammonia + PVA adhesive was replaced by a non-toxic, higher-resolution diazonium salt + PVA + PVAC photoresist. As the photochemical plate making method gradually replaced the traditional manual engraving film and manual drawing plate making, the plate making speed, plate resolution, and printing rate were improved, and the yield was also greatly increased. Screen printing plate technology has been increasingly improved, not only screen printing on the ground and lines, but also able to produce high-quality color version, printing quality has reached a considerable level. In August 1983, Beijing Institute of Printing Technology and the Swiss screen printing industry expert Mr. Akermann jointly produced a four-color screened parrot painting (70 lines/inch to 350 mesh/inch).

In the 1990s, it was the era of professional development and automation of the screen printing industry in China. There were more than 200 screen printing equipment and equipment manufacturers distributed in 17 provinces, municipalities, and autonomous regions throughout the country, and most of them began to take shape. There are more than 300 equipment and equipment sales outlets nationwide, and the supply and demand channels are basically open. There are also nearly 10 scientific research units engaged in screen printing technology, and the conditions for the smooth flow of information and technical exchanges have also been met. What is more important is to cultivate a large screen printing technology team. China's modern screen printing integrated support has gradually formed, and it has its own industrial base and service system.

Overview of Screen Printing Machinery Equipment Produced in the Mainland
With the continuous expansion of the mainland screen printing market and the increase in demand, the number of manufacturers engaged in the development and production of screen printing machinery equipment has increased rapidly. The existing screen printing machinery manufacturers nearly 100, begun to take shape, the formation of a certain amount of production capacity of more than 40. From a variety point of view, there are 8 electronic special screen printing equipment manufacturers, 2 multi-function screen printers, 5 pad printers, 4 thermal transfer printers, and other general-purpose screen printing equipment, with 7,180 employees, 95 production capacity. About 5,000 units (excluding manual platform), sales of 20169 million yuan. Imported machine sales amounted to about 150 million yuan. It is mainly distributed in Guangdong, Shanghai, Beijing, Jiangsu, Zhejiang, Fujian and Hebei provinces and cities. There are more than 40 product varieties, pneumatic, semi-automatic, three-quarters of automatic, fully automatic, monochrome and multi-color, plane and surface machines. Multifunctional machine. From the model point of view, there are many domestic screen printing machines and pneumatic lifting. Basic equipment for plate-making equipment, manual, pneumatic, fully automatic net machine, various specifications and models of aluminum alloy frame, various specifications of the dryer, various light sources and different types of printing machine, etc. Low grade, can basically meet the needs of domestic screen printing. Domestic large-format long-length screen printers began to be marketed, large-scale projectors have been prototyped, and desktop color publishing systems tend to be perfect. There are many types of peripheral equipment such as pad printers, heat transfer machines, and trademark machines, and their output and quality have been continuously improved.

Domestic screen-making screen
The use of medium and low grade screens in plate making in the Mainland has basically met the current market needs. With the development of the screen printing industry, the demand for screens is increasing and the quality requirements are higher. In the 1980s and early 1990s, the Shanghai Screen Factory produced 300 mesh/inch polyester monofilament plain weave by introducing advanced equipment, equipment and raw materials, which provided domestically-made screens for high-precision screen printing. The factory also produces silk, nylon, polyester and metal mesh, more than 100 varieties of specifications. There are also more than 50 companies in Jiangsu Wuxi, Zhenjiang, Suzhou, Taicang, Zhangjiagang, Zhejiang Huangyan, Xiaoshan, Tiantai, Wenzhou, Ganzhou and Henan, Anhui, Hebei, and other places are also engaged in screen production. It has begun to take shape with about 15 companies and about 1,000 people. The annual production volume is about 15 million square meters, of which 70% is of low and medium order, basically meets the domestic market demand, and has a small amount of exports. A large number of screens produced in China are low and medium mesh nylon screens and polyester screens. Polyester mesh has only five plain and 10 square-frame specifications. Its variety and internal quality have not yet reached the technical level of similar foreign products. High-mesh screens of 300 mesh/inch or more are still blank. A large number of imported medium and high-grade silk screens and special wire meshes, and the annual sales of imported screens amounted to approximately 120 million yuan.
