Reason 1: Caused by warping of corrugated cardboard
If the corrugated cardboard is not warped well, it is easy to slip during the positioning and feeding process, and even the rules on the machine cannot touch the edge of the paper, resulting in inaccurate or unstable printing position of the cardboard.
method:
When printing on warped corrugated cardboard, try to use relatively flat paper edges as conventional paper edges when feeding.The important thing is the control of the source of quality.Through reasonable control of the operation process of the single-sided machine, the speed of the machine, the preheating temperature, the moisture content of the base paper and the preheating area are in a relatively coordinated state; when dispensing paper, pay attention to the moisture. Corrugated cardboard and corrugated paper are bonded together to form a configuration, so that the corrugated cardboard produced has a relatively good flatness, which can effectively ensure the accuracy of the printing position.
Reason two: Caused by improper operation process
If the loading position is improper, it is easy to cause inaccurate layout printing position.Because the corrugated cardboard with warping defects has just entered the printing plate roller, if there is a slight slippage, the tip of the cardboard will be significantly skewed.
method:
When corrugated cardboard has a color layout, the paper should be oriented as far as possible towards the starting position of the drum, and corresponding measures should be determined accordingly.Only when the parts are loose can the accuracy of the printing position of corrugated cardboard be guaranteed.
Reason three: Caused by the broken machine
When the chains, rules and other parts of the machine are loose, it is easy to cause inaccurate printing positions of the layout.
method:
Only after the parts are loose, corresponding measures should be taken to ensure the accuracy of the printing position of corrugated cardboard.
