Most of the lithographic printing uses offset printing, and the printed images are first transferred to a relatively flexible blanket cylinder and then transferred to paper, usually called offset printing. Since offset printing utilizes the characteristics of rubber, compared with direct printing from printing plate to paper, the printing life is long, the surface of the printed matter is compact, the latitude of the paper is large, the plate making is simple, the reprinting speed is fast, and the printing cost is low. Multi-color printing.
However, its printing characteristics determine the amount of ink transferred by the ink to the paper is small, the amount of ink transferred from the printing plate to the blanket is about 50%, and the transfer amount from the blanket to the paper is about 75% to 80%, that is, the printing. The amount of ink on the plate is only about 37% to 40% transferred to the paper, so the printing surface concentration is lighter, and because the use of water, the printing surface is not shiny.
At present, the major categories of blankets can be divided into ordinary type (field type) and compression type (air cushion type). Since the air-cushion-type blanket has a microporous oily cotton layer between the layers, the blanket itself is highly compressible and can exhibit its special features in high-speed printing.
First, foreign applications and development since the 1990s, with the development of offset printing technology, printing machinery, and the subdivision of the printing market, blankets have become increasingly important in the printing process, and people also hope that the shape and characteristics of the blanket Can meet more and more subdivided market demand. Due to the different industrial bases and the impact of economic values, the printing speed of developed countries is generally higher than that of domestic printers. The main factor is that the labor costs are high. In order to fully utilize the advantages of high-speed operation of printing presses, the demand for auxiliary working hours is almost exacting, and thus universally adopted. Air cushion blanket with better high-speed operation adaptability. According to the Japanese market analysis, the ratio of air-cushion blankets to ordinary blankets is 9:1. In order to reduce the installation time, most of the blankets are equipped with aluminum cards or steel plates at both ends, and screw splints are no longer used. In order to further save costs, the blanket manufacturer will closely follow the requirements of new technologies for slits and seamless offset presses. The process of manual cleaning of blankets will be gradually replaced by environmental protection and automatic cleaning.
According to relevant statistics in 1995, the total global blanket market demand is about 5 million m2, of which North America accounts for 32%, Europe 31%, Japan 9.4%, Southeast Asia 9.0%, Central America 6.3%, Russia 2.5%, China 5.2%.
The production of rubber blankets is linked to patents and production technologies such as rubber, textiles, printing, and related production equipment is also dedicated machinery. International blankets are mainly produced in developed countries such as the United States, Britain, Japan, Germany and France. The famous brands include DAY of the United States, Meiji of Japan, Jinyang, Rollin of France and Vulcan of Italy.
Second, domestic production and demand According to the China Printing and Equipment and Equipment Industry Association printing equipment branch 1998 and 1999 statistics show that its statistical 11 blanket production plant in 1999 the total actual production capacity increased by 120.4% over 1998, reaching 130.3 Million m2, but in 1998 the average utilization rate of equipment was 60.9%, only 56.9% in 1999. It can be seen that the balance between domestic production and demand has been broken, and the actual production capacity has far exceeded the market demand, and some plant equipment utilization rate is only 20% to 30%.
Statistics in 1999 showed that the total sales volume of domestic production plants was 740,000 m2. Taking into account the export volume of some production plants and the foam factors reported by various plants, I estimated that the actual demand in the domestic market was 550-660,000 m2. Among them, air-cushioned rubber blankets accounted for 25% to 30% (including the number of imported blankets), which was nearly doubled compared with 10 years ago.
On the domestic blanket, from the perspective of product quality, can compete with the imported air-cushion blanket, in the same grade, only the Sino-Japanese joint venture Shanghai Meiji company's products. In the field blanket market, due to low-speed printing, the technical indicators are lower, the production process is similar, the quality is not much difference, the leading brand is Shanghai's Chunlei, Xingpai; from the product variety, relatively single, Insufficient refinement, only suitable for medium and low-speed printing; from the perspective of product prices, imported air-cushion blankets are more than 1 times higher than domestically-made air-cushion blankets, and the field blankets are only 1/4 of the air-cushion blankets, of course, performance-cost ratio. Is different; from the domestic market demand, on-site blanket supply exceeds demand, due to low-speed printing on the technical indicators are not demanding, the price has become the first competitive factor. However, foreign rubber blankets in the field are much higher than domestic prices, and are not limited to low-speed printing. Therefore, they will not participate in the domestic blanket market competition. The only company in Shanghai that manufactures air-cushion blankets is an export-oriented company. Its air-cushioned blanket can replace some imports, but there is a considerable proportion of exports. Therefore, in terms of quantity and variety, it cannot fully meet the domestic air-cushion blanket market. Demand, supply inevitably has input for imported products. (To be continued)
