Post-Press Experience Exchange: Analysis of Paperboard Die-Cut Indentation (3)

Maintenance personnel should identify the cause of the machine failure and take appropriate repair measures to prevent the indentation line from bursting.
The offset of the indentation line is caused by the displacement of the pad plate. Due to the effects of pressure, vibration and other factors, the offset printing plate is easily moved to make the local indentation line higher during the die cutting process, causing the indentation line to burst. To prevent this from happening, the backing block must be glued. If it is due to the explosion of the steel plate underlay paper, the pad should be thinned. In the middle of production, the products should be carefully checked and the cause of the malfunction should be promptly eliminated.
