1, it should be the version of the problem;

2, look at the PS version of the state, and the state of the water to determine whether the PS version of the reason or water, of course, but also to check the water stick on the version and by channeling the pressure of water;

3, three factors: the first version of the problem, is the CTP version or PS version. Different processing methods. Second, fountain solution over standard or oil: in the water, according to the standard run version of the liquid parameters with, third, ink emulsification, car wash for new ink. Of course, the correct regulation of ink roller is a must; there is no problem to try to press standards, so that a lot of problems;

4, I also encountered, we are out of the CTP, when we changed a new version, but still can not open for long, and finally found out is the problem of fountain solution, because the ratio of water is a problem.
