1. There should be a problem with the version;
2. Check the status of the ps version and the status of the water to determine whether the reason is the ps version or the water. Of course, check the pressure of the water stick against the version and against the water stick;
3. Three factors: the first printing plate is the CTP version or the PS version. The treatment methods are different. Second, the fountain solution exceeds the standard or has grease: change the water and prepare it according to the standard fountain solution parameters. Third, if the ink is excessively emulsified, wash the car and replace it with new ink. Of course, it is necessary to adjust the ink roller correctly; If there are any problems, we should try our best to follow the standards, so that there will be fewer problems;
4. I have also encountered that we issued a CTP. At that time, we changed a new version, but it didn't last long. Finally, it was found that the problem was the fountain solution, because there was a problem with the water ratio.
