The Indentation Line On The Cardboard Is Not Clear

- May 23, 2018-

The indentation of the printing press is achieved by pressure rolling at the corresponding points of the male and female wheels, wherein the shaft of the concave wheel can be adjusted to maintain the clearance required for the indentation with the male wheel. If the concave wheel is adjusted too low, it will cause insufficient pressure to make the indentation line unclear. In addition, if the shaft of the convex wheel and the concave wheel is loose, the indentation line may be unclear. Therefore, after the cause should be identified, appropriate measures should be taken to adjust and deal with it.
