1. Check the flatness of its surface. The way to check is to play full version, but the printing pressure should be lower than normal pressure. Only in this way can the unevenness of the surface be exposed. If the pressure is too great and the ground is thick, it is difficult to see the difference.
2. If the unevenness of the surface is unacceptable (specific indicators can be judged by experience), you can check the uniformity of the surface of the blanket and liner and whether there are foreign objects on the surface of the roller. After removing the foreign objects, if the unevenness still exists, you can use the method of drawing a "map". First draw each low (or false) place, and then place a sticker on the back of the blanket (the thickness of the paper is selected according to the situation).
3. If the surface of the blanket is damaged during use, the solution is the same as 2. However, if the blanket is scratched, the image formed by it is emptied or blank in the middle, and it continuously transitions to the surroundings to a place that is not crushed. This is one of the most obvious signs of judging the blanket being sagged.
4. The surface of the blanket should be acid and oil resistant to prevent its surface layer from being destroyed. The frequent contact of the blanket with oil can cause its aging, and finally loosen its internal organization. The frequent contact between the blanket and the acidic substance will cause the surface to corrode. It should be cleaned with fast volatile detergents, such as gasoline, instead of volatile substances such as kerosene.
5. Creep and stress relaxation of the blanket. After the blanket is stressed for a long time, there are two kinds of performance: a if the length is constant, the stress gradually decreases, which is called the stress relaxation; b if the stress is constant, the length will gradually increase, which is called the creep. After the blanket is installed on the roller, the length will not change, which will cause stress relaxation. Therefore, after a period of use, the blanket needs to be re-tightened. If you don't use it for a long time, you should loosen the blanket to avoid stress relaxation.
6. The surface of the blanket should be kept clean. The effective parts of printing need to be kept clean frequently.
If it is not clean, it will affect the printing pressure. When padding the blanket, the paper usually used is around 0.05mm, and there is a clear difference in the reproduction of the pad and non-pad pads. This shows the effect of this 0.05mm thick paper. In fact, the paper with a thickness of 0.05mm increases the printing pressure by 0.05mm (generally, the printing pressure is between 0.05-0.25mm). If ink or other impurities are fixed on the surface of the blanket, the printing pressure will change, thus Print quality has an impact. Non-printed parts should also be kept clean. This is because when the blanket at the printed part is damaged, sometimes the second half of the rubber (usually the printed surface will not exceed the entire blanket) is borrowed. If this part is not kept clean, as the sludge and other impurities continue to condense, and the printing pressure continues to increase, the surface of the blanket will be damaged and cannot be used normally. The increase in printing pressure will also bring other problems, which will be described later. Keeping the surface of the blanket clean should also pay attention to the junction of the effective parts of the printing, which has the most condensed ink and other impurities. Due to the increased pressure, the fatigue of the blanket is accelerated. In practice, it has been found that the blanket in this part is most prone to cracks. Therefore, impurities must be prevented from accumulating here.
