Today's machinery is made of high-quality alloy steel and should be able to be used for a long time. Afterwards, the manufacturers gradually began to discover the important role played by the maintenance material team in maintaining the normal operation of the printing machinery after paying huge maintenance fees and delaying the production. The related chemical products are relatively neglected. It may be that the correct selection of these materials will not cause immediate adverse effects on the finished products produced by the manufacturer.

Mechanical equipment is often found to have problems after a long period of use. Machines that print text and images. Modern printing machines are generally composed of plates, inking, embossing, paper feeding (including folding) and other mechanisms. Its working principle is: first make the text and images to be printed into a printing plate, install it on the printing machine, and then manually or by the printing machine apply the ink to the place with the text and image on the printing plate, and then directly or indirectly transfer it. Printing onto paper or other substrates such as textiles, sheet metal, plastic, leather, wood, glass and ceramics to reproduce the same print as the printing plate.
