Since the static electricity of the object to be eliminated has been guaranteed before printing, why is it still necessary to remove static electricity during the printing process?
At present, the main printing processes in the domestic market are divided into three types: emboss printing, offset printing, and screen printing. In their printing process, many frictions are generated, so that the static electricity on the surface of the object will be much higher. If the static electricity is not well controlled during printing, it is easy to cause electrostatic ink shifts and cross-color phenomena on the printed matter. , And in the printing process, due to high-speed friction, peeling will generate static electricity and the accumulation of static electricity can easily lead to air discharge, resulting in electric shock or fire. So how can we control the generation and elimination of static electricity in the printing process? It is to ensure that the substrate has no static electricity before contacting it, and also that there is no static electricity on the surface of the finished printed matter. This process is very cumbersome and simple. In other words, it is necessary to ensure that there are absolutely enough negative ions in the printing process to give the object to be eliminated.
