Why does the machine produce abnormal noise during operation?

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: 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.

A: This issue is commonly caused by:
• Excessive printing speed
• Ink viscosity that is too low
• Excessive pressure between printing rollers

Solution:
Reduce the printing speed appropriately, adjust the ink viscosity to the recommended range, and decrease roller pressure to a stable and controlled level.
Note: Ink misting not only affects print quality but also increases machine contamination and maintenance frequency.
