Many manufacturers are pursuing high quality and high precision when printing thin films. This is a consistent standard in the industry, and there is a lot of stress here.
The high quality of the product will inevitably depend on the high quality of the equipment. What are the guarantee systems for the accuracy of gravure printing machine?
Transfer guide roller (passing guide roller):
Many wear guide rollers require not only flexible rotation but also good dynamic and static balance. Imagine that if the prints passed by each of the feed rollers are a little bit resistant, the unsynchronized resistance and static electricity generated during the printing of the print film will be difficult to guarantee the accuracy of the prints.
Gravure printing machine tension control section:
The feeding site needs to be done when unwinding: the film roll is large and the tension is small; the film roll is small and the tension is large. The receiving part requires: the film roll is small and the tension is small; the film roll is large and the tension is large. That is, when the unwinding film is unwound, the tension is small, and as the film roll is reduced, the tension is gradually increased. When the receiving film is unwound, the tension is small, and as the film roll increases, the tension gradually increases. During printing, the printed material, that is, the paper or film of the printed matter always has the same tension. When the material is discharged, the tension of the paper or the film is stable, and the tension of the received paper or film is also stable. Prints will not run in order to maintain the accuracy of the layout.
