The reason:
1. The printing plate is not sensitive to grease.
2. The paper powder that has fallen off the surface of the paper wears on the surface.
3. The printing pressure is too strong and the graphic film of the layout is worn away.
4. The acidity of the dampening solution is too strong, causing the plate to corrode and the image to fall off.
Countermeasures:
1. Replace the plate
2. Replace paper of better quality and use less viscous ink.
3. Adjust printing pressure to reduce wear
4. Strictly control the pH of the dampening solution
