[0002] The printing roller is one of the accessories of the offset printing machine. The performance of the printing roller directly affects the printing quality. During the printing process, foreign matter will remain on the surface of the printing roller. If the remaining foreign matter is not cleaned in time, it will cause glaze on the surface of the printing roller. After glazing, the surface area of ​​the printing roller is lost. At the same time, the hardness of the rubber roller increases and its elasticity decreases. Therefore, foreign matter on the surface of the printing roller must be cleaned after each printing is completed.
