An important quality index of printing materials is service life, which is more prominent in PS plate, blanket, cots and other durable materials. The material purchase cost and service life are inversely proportional to a certain period of time. The use of good quality printing materials not only improves the use efficiency and the quality of printed materials, but also extends the service life and reduces the shutdown loss. The effect of service life on the cost of materials is very obvious. Compared with a PS plate which can print 60000 copies and 120000 copies, the difference is intuitive and easy to calculate, and there is also the advantage of improving the quality of printed materials. A qualified material purchaser or manager must consider the service life of materials together with the price. Experience tells us that the service life and sales price of materials are not all increased by the ratio of 1:1, most of which is that the growth rate of price is lower than that of life extension. Only when the quality is improved to a certain extent, there will be a separate price increase, and no longer involves the growth of service life. At this time, there must be a principle, if the price growth is slower than the growth of service life, then better quality materials should be selected. However, most purchasers and even decision-makers can not grasp the service life of materials well. They are neither printing technicians nor technicians, and often prefer to accept the opinions of suppliers rather than listen to the views of front-line workers. Of course, there is also the problem of insufficient data management. Although some enterprises record and summarize the service life data of various materials, they have not formed a set of data system with reference value. It is necessary to discuss the technical relationship between the service life of materials and the selling price. The main factors affecting the service life of printing materials are aging and damage, which are closely related to the selection of raw materials and the production process. If the raw materials are selected well and the processing technology is good, the printing process characteristics will be good and the service life will be prolonged accordingly. From the price composition of raw materials, whether it is chemical raw materials or metal raw materials, the incoming price is often basically determined, and the price change caused by production process becomes the main factor of raw material price changing with quality. Take PS plate as an example, its aluminum plate, photosensitizer, etc. are priced by weight. However, there will be great differences in the reprocessing process of raw materials after entering the factory, which becomes the main factor leading to the price change of the final product. Therefore, the service life of the product will not increase at the same speed with the cost. Sometimes the price of a product is related to the selection of its main materials. A low-cost product is bound to be low-cost, and the best way to reduce the cost is to reduce the amount of raw materials, which will directly affect its service life. Taking the PS plate for newspaper industry as an example, the printing press is designed according to the thickness of 0.30mm, and the minimum is 0.28mm. Some domestic PS plates have a nominal thickness of 0.28mm and a large downward tolerance, while imported PS plates have a nominal thickness of 0.30mm, and the downward tolerance is very small. If the thickness of low price PS plate is lower than the tolerance requirement, it will lead to insufficient pressure during printing. The solution is to increase the amount of blanket liner, which leads to the inconsistency of linear speed between plate cylinder and blanket cylinder, thus speeding up plate wear. Although the aluminum material is saved, the sales price is reduced, but the printing resistance is very poor, and in some cases, it can even be twice as bad. As more and more social capital is involved in the production of printing materials, the quality of printing materials has been greatly differentiated, and the differentiation of service life is also prominent. Therefore, it is necessary to pay attention to the comparative relationship between service life and price in order to obtain the lowest material cost. Of course, material procurement should be combined with production needs, and service life should not be blindly pursued. For example, for a product with a small printing capacity, no matter how high the printing resistance of the printing plate is, there is no practical significance; for a printed piece with a large printing volume, the material cost changes caused by the printing plate resistance must be considered.
