Some printers reflect that it is inevitable to have some problems during printing, such as the phenomenon of flying ink is a common problem, so in order to solve the problem, we need to find the cause.
When printing, the relative humidity of the air is low, which promotes the generation of flying ink. When the humidity increases, the charge decreases and the amount of flying ink becomes smaller. If the ink version of the solution is too much, the viscosity will drop sharply, the ink becomes short, will cause serious flying ink phenomenon. Repulsive ink, resulting in metal roller deinking.
The thicker the ink layer on the roller, the bigger the flying ink. When the paper performance of ink adhesion is not good, it is easy to cause ink roller accumulation, resulting in flying ink phenomenon. High molecular weight ink adhesive in ink splitting easy to elongate wire, resulting in flying ink. In addition, when the surface of the ink roller is uneven, the surface is dry and cracked, part of the ink layer thickens, the amount of ink mist increases, which is also one of the factors causing the phenomenon of flying ink. If the speed is too fast, the chances of ink splattering are higher.
Ji 'nan printers here to remind you that if the viscosity of the ink is too large, the ink will be stretched at the exit of the ink roll, easy to produce flying ink, but also cause uneven ink transfer, so that the paper wool and powder, paper will be difficult to peel from the blanket, easy to embossing and falling. If the viscosity is too small, ink layer splitting is not good, easy to produce flying ink. At the same time easy emulsion ink, paste version, expand dot, affect the quality of printing.
Why does flying ink appear when printing? The above is the cause of the problem. If you want to complete the printing process smoothly and have good quality, you should pay attention to prevention. For more information, visit www.703248.com.濟南印刷廠講解的內容 更多的內容 請咨詢公司官網http://www.703248.com/
