Carton printing and die-cutting machines are essential equipment in the packaging industry. However, long-term use can lead to faults, affecting production efficiency. This article introduces 5 common faults and their solutions to help you quickly resolve issues and reduce downtime.

1. Blurry Printing or Ghosting

Possible Causes:

• Worn or improperly installed printing plate
• Uneven or aged ink roller pressure
• Ink viscosity too high or too low
• Uneven paper surface

Solutions:

• Inspect the printing plate and replace or reinstall if necessary
• Adjust ink roller pressure or replace aged rollers
• Adjust ink viscosity according to paper type
• Use paper with a smooth surface

2. Inaccurate Die-Cutting or Burrs

Possible Causes:

• Worn or loose die-cutting blades
• Insufficient or excessive die-cutting pressure
• Uneven or damaged die-cutting base
• Uneven paper thickness

Solutions:

• Replace or tighten die-cutting blades
• Adjust die-cutting pressure to the appropriate range
• Replace or repair the die-cutting base
• Use paper with uniform thickness
