Why Cleaning Method Matters
A dirty anilox roller cannot transfer ink accurately.
As contamination builds within engraved cells, printers often experience:
- Reduced colour density
- Inconsistent print quality
- Higher waste levels
- Longer setup times
Selecting the correct cleaning method can significantly improve production performance.
What Is Ultrasonic Cleaning?
Ultrasonic systems use sound waves within a liquid cleaning solution to remove contamination from engraved cells.
Advantages
- Effective for routine cleaning
- Widely used in the industry
- Suitable for many types of residue
Considerations
- Cleaning effectiveness depends on contamination level
- Results can vary between systems
What Is Laser Cleaning?
Laser cleaning uses controlled laser energy to remove contamination from the cell structure without physical contact.
The process vaporises residues while preserving the ceramic surface.
Benefits of Laser Cleaning
Greater Removal of Embedded Contamination
Laser cleaning can restore cells that conventional methods struggle to recover.
Consistent Results
The process is highly repeatable.
Non-Contact Technology
There are no brushes or abrasive media contacting the roller.
Reduced Chemical Usage
Laser systems generally require fewer chemicals than alternative methods.
Which Method Delivers Better Results?
For routine maintenance, ultrasonic cleaning remains an effective option.
For heavily contaminated rollers where maximum cell recovery is required, laser cleaning often provides superior results.
FAQ
Is laser cleaning safe for ceramic surfaces?
Yes, when performed correctly.
Which method restores more cell volume?
Laser cleaning generally achieves greater recovery where contamination is deeply embedded
