Why are the creasing lines unclear or broken?

A: This issue is usually related to:
• Unbalanced rollers
• Loose transmission components
• Excessive operating speed beyond machine design limits
Solution:
Balance the rollers, tighten transmission components, and operate the machine within the recommended speed range.
Note: Stable operation ensures better print quality and extends machine lifespan.

A: Possible causes include:
• Loose mechanical components
• Insufficient lubrication
• Bearing wear

Solution:
Stop the machine immediately, inspect all fasteners, apply proper lubrication, and replace worn bearings if necessary.
Note: Abnormal noise is an early warning signal and should never be ignored.

A: This is often caused by:
• Excessive printing pressure
• Poor-quality or incompatible printing plates
• Improper plate installation

Solution:
Reduce printing pressure, use qualified flexo plates designed for water-based ink, and ensure correct plate mounting.
Note: Proper pressure control significantly extends plate service life.

A: Common reasons include:
• Poor ink drying performance
• High ambient humidity
• Insufficient ventilation or drying airflow

Solution:
Use water-based ink suitable for the local climate, improve workshop ventilation, and enhance air circulation in the printing section.
Note: Environmental conditions have a direct impact on water-based ink drying speed.

A: This problem is usually related to:
• Ink viscosity is too low
• Insufficient pressure between rollers
• Clogged anilox roller cells

Solution:
Increase ink viscosity to the recommended level, adjust roller pressure, and clean the anilox roller thoroughly.
Note: Regular anilox cleaning is critical for stable and repeatable print results.
