The operator of the offset printing press will encounter such a situation when cleaning the impression cylinder after the shift: During the work, due to the pressure contact of the impression cylinder with the blanket cylinder several times, different degrees of stickiness may occur at the trailing portion. Especially in the high temperature season and without air conditioning, in a short shift of time, the ink particles sticking to the trailing edge will harden and crystallize and stick firmly to the roller. When cleaning, you need to rub it back and forth with the ancient cloth, and hit a stubborn place. You need to scrape it with a steel blade. If it is light, it will not be clean. If it is heavy, it will damage the cylinder. When cleaning the impression cylinder body, the author tried to scrub the cylinder body with a clean ball and gasoline bought in a department store. The effect was good.
