Print shop equipment to help the current situation and needs analysis

Auxiliary printing equipment is in the process of printing a small amount, but print quality and stability of the impact of very large part of the printing equipment, such as: printing Cots, blankets, Fountain Solution, as well as cleaning and maintenance chemicals, and so on.

Offset printing used in printing equipment, in addition to paper, ink, PS version, there are equipment parts, chemicals, rubber roller and blanket, and other areas. At present, most of the domestic printing enterprises are aware of the paper, ink, PS version, as well as printing machinery parts in the process of the important role, but when they are in the printing equipment, new equipment and even the use of first-rate paper, ink, PS version for printing operations , Will still find fault in the printing and printing issues continue to occur. In fact, even if the use of the same paper, ink, PS version, and the use of different aids in both printed on the printing operation, will find that the quality of printing in the stability of the differences. However, many of the current mix of different printing standards with the printing aids for printing, or very little production in accordance with their own characteristics, its own request for a print campaign aids, which often resulted in a number of printing faults, such as: automatic cleaning Plug the system, Roller absorption of impurities, such as printing too much pressure. Therefore, in order to guarantee the stability of the printing enterprises in accordance with the needs of their own characteristics and the characteristics of aids to choose their own high-quality printing aids so that they form a complete series of printing aids.

In the development of high-speed offset printing now, the printing quality is getting higher and higher, and high-quality printing, printing workers in the printing of smooth has a very high demand. To ensure the smooth progress of the printing process to prevent the printing problems, a series of high-quality printing aids played an increasingly prominent role.

A printing blanket

Printing Blanket, with the majority being offset printing blanket, iron-Indian blanket, a wide range of printed plastic sheets lining, the most important of which is offset printing blanket. Lithographic printing all the way to use up most of a wide range of printing, and ink, PS version of the paper, offset printing blanket is in the middle of the media played a role, its importance lies in the possibility of plate On the integrity of ink quickly transfer to the paper, which blanket on the variety, high quality requirements of the offset printing blanket offset is a very important material.

Blanket offset domestic development and production began in the mid-1960s, by the printing equipment factory in Shanghai and Shanghai Institute of Printing Technology Development, to 70 in the early domestic production only two ordinary blanket, the annual production of about 20,000 Square meters, there are still a lot of reliance on imports. By the mid-80, general domestic production of offset printing blanket is about 100,000 square meters or so, the blanket of imports has been reduced, but the air-cushion Blanket domestic production can not completely rely on imports. By the mid-1990s, made common offset blanket technology has matured.

Blanket cushion the market is divided into three: the first by a Japanese Meiji Rubber Co., Ltd., printing equipment factory in Shanghai, China Printing Materials Corporation, China's foreign trade publishing joint venture established by the Shanghai headquarters of the Meiji Rubber Products Co., Ltd. produced the Meiji 9600A Air Blanket; second is a variety of brands of imported air-cushion Blanket; block is the third China-made air-cushion blanket. Statistics show that in 2002 the National Printing Blanket actual yield 990,200 square meters, and 26.79 percent growth over the previous year; sales income 220,000,000 yuan, a 24% increase over the previous year. Blanket air-cushion which 381,000 square meters, and 26.16 percent growth over the previous year, the development trend, showing a booming production and sales momentum. From the market point of view, the use of air-cushion Blanket growth faster than expected, the South and the coastal areas of the blanket use of air has reached more than 80%. At present, the domestic rubber factory in the city is actively developing air blanket, but limited to raw materials, technology, equipment, design, test equipment and many other reasons, most of the domestic air-cushion belonging to the low-grade products, and air quality compared Blanket There is a certain gap.

Second, Roller

Cots in the metal coating on the core layer by the vulcanization of rubber made of rubber. And the metal roll, roll flexible plastic, acid, not rusty, and other characteristics, it is widely used in paper making, printing and dyeing, such as rice milling industry, as well as agriculture and other industries. Roller is the first in place of metal as a mechanical transfer or roll up pieces of support; followed by the use of the rubber layer of elastic deformation, so that the material is processed by a certain degree of pressure arising role of the press.

Cots are the main materials: natural rubber, nitrile rubber, silicone rubber, polyurethane, and so on.

Roller printing presses in China is also a very important supplementary print materials, its high-end printing press demanding, especially on the Mexican version of the roll on and roll version of the water. Judging from the current domestic production of printed cot, small to medium-sized, mostly low-grade products, supporting most of the common offset printing press manufacturer for the renovation of the old Roller, can only be used in low-speed printing press, not a long life. More than high-end multi-color offset press machine on the cot, or the vast majority of import-dependent, and some direct imports, and some use of imported materials produced cot mixed. With the high-speed multi-color offset towards the direction of development, to enhance the awareness of environmental protection, wetting alcohol will be controlled, high-quality printing presses of the cot demand is growing.

Third, the ink cleaning agent

The offset ink wash, the first is the use of gasoline. Leaded petrol and unleaded is divided into two types. Despite the strong gasoline to the ink's ability to clean the ink well, but because of too much harm to the human body, serious environmental pollution and a fire hazard, as it was the first generation of ink detergent is gradually phased out of gasoline .

As early as after World War II, the world's developed the printing industry and the importance of environmental protection in some countries embarked on the research and development of new ink cleaners. Offset Ink New detergents, by solvents, rubber Anti-aging agent and the emulsifier, such as a mixture of liquid, adding a certain amount of water available. Ink on a good washing, so that the ink roller will not expand or shrink the layer. Flash point for 21 to 55 degrees Celsius for the flammable liquid detergent, people call the second generation of ink cleaner. Flash point for 55 to 80 degrees centigrade aromatic substance-free detergent and chlorinated hydrocarbons, the solvent composition of the distillate can be no environmental problems due to the low-volatile, non-burning, safe use, is the internationally recommended The use of ink cleaning agent.

The printing press cleaning process is clearly affected the printing industry's production efficiency and social benefits. In addition, the cot in the maintenance of clean, a great number of vendors in the market do the work. Now a lot of printing, especially in the coastal areas of the printing house has printed more and more attention to maintenance of the important role of high-quality ink cleaner has a broad development space.
