Why is Ink and OV Mist Control Important?
Ink and Over Varnish Mist Control in the Decorator
During high-speed can decoration, both ink and Over Varnish (OV) mist can be generated inside the Decorator. These mists are made up of fine airborne particles and Volatile Organic Compounds (VOCs), and controlling them is essential for maintaining a safe, clean, and efficient work environment.
Why Mist Control Is Critical
Ink and OV mist pose multiple challenges:
- Health Risks: VOCs and fine particulates are hazardous if inhaled, requiring proper containment to protect operators.
- Maintenance Issues: Mist settles on internal machine components, leading to buildup and unplanned downtime.
- Workplace Cleanliness: Uncontrolled mist can spread beyond the Decorator, impacting surrounding equipment and processes.
How It’s Managed
Mist control systems use extraction hoods and ducting to capture airborne particles directly at the source. The air is pulled through multi-stage filtration systems designed to trap ink and OV particles before clean air is exhausted from the system.
Proper mist extraction is essential for:
- Complying with air quality standards
- Reducing maintenance frequency
- Protecting employee health
- Ensuring a stable decorating environment
