To do a good job, it is necessary to clearly understand the influence of different stretch screen tensions on the ink flow, and the influence of multiple factors on the printed matter after the combination of each other, and according to the magnitude of the influence effect, the influence factors and corresponding results should be arranged in a certain order Arrange, record in the manual, until the experience can be remembered. When troubleshooting, the most important thing is to know that a problem is usually caused by many reasons, and one reason may lead to different problems. The problem cannot be solved overnight, otherwise the problem will become worse. On the other hand, if you only perform one step at a time and the problem gets worse, it proves that your judgment is correct, but the adjustment method is wrong. If the problem improves, it proves that you have found at least one cause and solved it correctly; if the problem persists, it proves that your judgment and operation have nothing to do with the problem; if the operation has been effective, it proves that the current problem is different from the past. For troubleshooting, the right tools are also very important. Although you can make judgments with rich experience, the detection of borrowed tools can better prove whether your judgments are correct. For example, troubleshooting of graphics and text requires measurement. At this time, a high-power magnifying glass (at least 100X) is an essential tool. Of course, it is better to use an electron microscope or a computer stereo microscope. When not only troubleshooting but also correcting problems and controlling the process, other tools are needed, such as micrometers, film thickness gauges, gap gauges, hardness gauges, tensiometers, viscometers, etc., and even a stopwatch is also necessary. It is necessary to compare the color with the earliest printed product to see if there is any obvious change; the quality inspector must do the first article inspection, process inspection and final inspection, and make a good quality record; the printing operator is specifically responsible for the product self-inspection, and must be careful Check one by one, once a problem is found, it needs to be quickly wiped off with a solvent and reworked.
