Once, the PS plate was partially torn and torn during the normal printing process after loading and pulling. After the fault occurs, if you continue to print, you will leave marks on the water and ink rollers to hide the hidden troubles. If you stop the printing and change the plate after shutting down, it will take time and waste of materials. In the work, the author found a way to deal with this issue. The practice has proved to be effective. The specific practices are as follows:
(1) If you find a rip, you should stop immediately.
(2) Check whether the overprint of the job is accurate. If the overprint is not allowed to result in tying, if the overprinting error is not large, one end of the PS plate can be pulled apart and the other end can be pulled in the opposite direction until the overprint of the job is accurate. At the same time, the top plate screw of the PS plate port and the tip of the tip should be tightly tightened to prevent running.
(3) Use a dry cloth to dry the water around the tear-off portion of the PS plate, and then use a tape to stick the tear-away portion of the PS plate to the platen. In this way, the rip-off part of the PS plate will not pull the plate water and the ink roller, but also solves the circumferential rotation of the plate cylinder in the normal printing process (since the centrifugal force generated by the rotation of the platen will cause the tearing-off part of the PS plate to continue expand).
