During the offset printing process, it is often seen that the printing master needs to stop the washing machine. People in the industry know that it is best to reduce the number of downtimes in the offset printing process of a job to ensure batch consistency of printing quality. So why does the operator need to stop the washing machine halfway? This is because during the offset printing process, the ink has to pass through a dozen ink rollers to separate ink, distribute ink and cross-ink, and finally transfer the ink to the printing plate. However, the ink transfer between the ink rollers is not 100%, and some ink remains on the ink rollers, gradually drying the conjunctiva, thereby changing the outer dimensions and printing suitability of the ink rollers, and making the ink transfers worse. , Had to shut down for cleaning. Therefore, the existing offset printing process requires that the ink roller must be cleaned in time after working for a period of time, which not only ensures the function of the ink roller, but also ensures the printing quality and printing efficiency. However, if there are frequent and frequent shutdowns of the ink roller cleaning, not only are there problems that reduce the consistency of print quality, that is, the color deviation of the printed products and the quality instability of different shades, but frequent shutdown processing will also affect the printing production efficiency, causing The excessive damage of the ink roller and the greater waste of cleaning materials increase the labor intensity of the master and produce a greater impact on the production environment. The method to improve the frequent cleaning of the ink roller is to improve the cleaning effect of the ink roller and reduce the frequency of cleaning the ink roller. In addition to improving the ink printing suitability and selecting the appropriate printing ink roller, the effective solution in the printing process is to use high-quality car wash water to clean the residual ink on the surface of the ink roller more thoroughly and restore the printing suitability of the ink roller, thereby reducing A series of printing quality problems and printing efficiency problems caused by the decline of the ink transfer performance of the ink roller. However, the importance of choosing the correct car wash water is often overlooked by some printing companies. They believe that the price of special car wash water is relatively high, and they are willing to choose cheap substitutes. In fact, only good-quality car wash water has sufficient cleaning ability, which is simple and easy to use, and does not contain harmful substances. It really plays the role of cleaning the ink roller, reducing the number of cleaning times, and improving the printing quality and production efficiency. The printing process generally requires a higher flash point for car wash water. The higher the flash point, the safer it is. Stronger cleaning ability. It has a protective effect on the ink roller of rubber material for a long time. It does not contain aromatic stimulating compounds. The certification does not damage human health; it can be applied and is not easy to damage the automatic cleaning device; it can meet the requirements of printing machinery and printing technology. There are a variety of UV car wash waters on the market. If an inappropriate car wash water is used, it may result in improper cleaning of the ink roller, or swell the ink roller, resulting in increased pressure and friction between the rollers, making the rubber ink The roller ages too quickly. Proper selection of appropriate car wash water to clean the ink rollers requires not only a comprehensive understanding of the performance indicators of high-quality car wash water, but also comprehensive consideration of production reality and cost performance.
