Adhesive trademark printing overprint is not allowed to troubleshoot a case

The factory is a four-color adhesive label printing machine, a few months after the use of registration is not allowed to fault, irregular stroke up and down 0.5 ~ 0.2mm.

First consider whether the adhesive sheet is not tight. Rewinding the self-adhesive web still does not solve the problem.

Then consider if there is a gap in which part of the machine. The drive gearbox driving the stroke adjustment was disassembled, and it was found that the clip spring design of the bicycle flywheel was used. Since the gear box is filled with oil twice a day, the oil has a little more space on the gear, and in some places, it causes the stroke to jump. The analysis found that the use of inferior engine oil resulted in the use of marked oil with good fluidity. The problem was completely solved and no overprint was found.
