The precision of film printing is what many manufacturers are pursuing. High quality and high precision are not just to mention, but there is much more to be said. The high quality of the product is inevitably indispensable for the high quality of the equipment. What are the guarantee systems for the accuracy of the gravure printing machine?
1. Transfer guide roller (feeding guide roller)
Numerous feeding guide rollers not only require flexible rotation, but also require good dynamic and static balance treatment. It is conceivable that if the printing material passed by each of the guide rolls has a little resistance, it is difficult to ensure the accuracy of the printed matter by the asynchronous resistance and static electricity generated in the printing film printing.
2, the tension control part
The discharge part needs to be done during 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, the tension is small; the film roll is large and the tension is large. That is, the tension of the discharge film is small when the film is unwound, and the tension is gradually increased as the film roll is reduced. When the film is unwound, the tension is small, and as the film roll increases, the tension gradually increases. The printed matter, that is, the paper or film to be printed, always maintains the same tension. The tension of the paper or film is stable when the material is discharged, and the tension of the paper or film is stable. Prints will not run the version in order to maintain the accuracy of the plate.
