Dusting - an obstacle to improving the quality of modern printing

The role of printing dusting in printing is only to prevent the undried printing ink just printed on the paper from coming into contact with the paper to cause tackiness. The effect is small but indispensable, except for printing equipment with a drying system. Most of the paper drying systems on the offset press are high-stage delivery, which is expensive. Domestic printing companies rarely order this system when they order printing presses. Therefore, most printing companies cannot use the powder to prevent the problem of stickiness of paper and printing ink. However, dusting has gradually become an obstacle to improve the quality of modern printing.

With the continuous development of printing technology, printing quality has become the basis for the survival and development of printing companies. Why do dusting become an obstacle to improving the quality of modern printing? First of all, dusting destroys the printing environment, and allows operators to work in a large amount of dusty environment for a long time. Most printing operators are inevitably suffering from such lung and tracheal diseases. With the legal exhibition in this printing industry, many companies have adopted imported high-speed printing equipment. The value of these devices is also high. The owners of many printing companies are jokingly saying that printing companies are working for printing equipment manufacturers. In a sense, this is actually the case. Therefore, how to protect their own printing equipment and effectively use the efficiency of these printing equipment is one of the important contents of modern printing enterprise management. It is difficult to imagine that the printing equipment can continue to perform well under long-term and dusty conditions. In order to protect the printing machine parts, the number of times of regularly cleaning the printing equipment is greatly increased, so that the maintenance time and maintenance cost of the printing equipment are also greatly increased.

Second, there are few companies in the commercial printing industry that have single-sheet 8-color machines and commercial rotary machines. Most companies still have four-plus-four secondary printing problems. After the powder is sprayed, the paper is affixed with dust particles. In the second printing, it not only affects the quality of the printing, but also the powder will be picked up from the paper onto the ink roller system. Not only affects the transmission of ink also greatly reduces the life of the ink roller, but also seriously reduces the service life of the printing blanket. Virtually increase the cost of production.

In the packaging industry, post-processing is more and more important, but now because the printing process is sprayed, the powder sticks to the paper, so that the scrap rate of glue, laminating, etc. is greatly increased. From product quality and production cost considerations have reached a problem that cannot be ignored. At the same time, the packaging industry has a relatively large amount of paper with heavy ink, so the particles of powder are also larger than those in commercial printing. Equipment in such an environment often suffers from mechanical problems in the printing delivery and transmission parts, and the cost and downtime of the printing press maintenance. Time is also a headache for business.
