Overcoming Marking Challenges on Paint Packaging with KGK Jet CIJ and Laser Solutions

Marking and coding on paint packaging has always been a demanding task for manufacturers. From rigid PVC buckets and metal containers to small plastic bottles, each substrate presents unique challenges. The surface properties—such as glossiness, curvature, and the presence of solvents or dust—can often lead to print smudging, fading, or even complete code failure. Yet, for traceability, regulatory compliance, and brand protection, accurate and permanent marking remains non-negotiable.

Challenges in Marking & Coding on Paint Packaging

Paint packaging lines operate in tough environments filled with dust, humidity, and solvent fumes. These factors can interfere with print quality and printer reliability.

• Varied Substrates: Paint buckets are often made from PVC, HDPE, or even coated metal. Each material reacts differently to inks and laser energy. Ink adhesion can be poor on glossy PVC, while laser coding on reflective metal requires precise energy control.
• Harsh Environment: The presence of paint dust and solvent vapors can damage printer electronics and clog printheads. Without proper protection, coding equipment often suffers from high maintenance costs and frequent downtime.
• Irregular Surfaces: Paint containers are typically curved or ribbed, making it difficult to achieve a consistent code on every package.
• Seasonal Production: Paint manufacturing often follows seasonal demand. Machines that remain idle for months may face start-up issues, clogging, or ink deterioration when production resumes.

KGK Jet: The Reliable Solution for Paint Industry Coding

KGK Jet addresses these challenges through its advanced CIJ (Continuous Inkjet) and Laser marking technologies, offering unmatched reliability and precision for industrial environments.

IP65 Ingress Protection for Tough Conditions

KGK Jet CIJ printers come with a durable stainless-steel cabinet and a sealed IP65-rated electronics enclosure, providing complete protection against dust and water. This rugged design ensures consistent operation even in paint production areas where humidity, solvent fumes, and color dust are present.

Inks for Different Needs

KGK Jet offers an extensive range of inks specifically formulated for different substrates—be it metal, rigid plastics or PVC,  These inks deliver high contrast, quick-drying, and long-lasting marks that resist smudging, peeling, or fading during post-production handling and storage. Whether marking on glossy paint buckets or metallic lids, KGK inks ensure legible and durable codes every time.

Low Maintenance and Nozzle Capping System

Downtime is costly in paint manufacturing. KGK Jet’s nozzle capping feature automatically seals the printhead when not in use, protecting the ink from contamination and preventing nozzle drying. This minimizes maintenance needs and keeps the production line running smoothly.

Auto Start & Stop for Seasonal Operation

For paint producers with seasonal production cycles, KGK Jet printers are designed with an Auto Maintain system. Even after long periods of inactivity, the printer can start instantly, ensuring consistent performance without the need for extensive cleaning or service need.

Compact and Ergonomic Design

The ergonomic printhead design allows easy integration in confined spaces, making it ideal for high-speed bucket or can production lines. Its low footprint helps maximize productivity and efficiency while reducing operator error.

Conclusion

Marking on paint packaging—whether on PVC, HDPE, or iron buckets—demands durable, adaptable, and reliable coding systems. KGK Jet CIJ and Laser marking machines meet these requirements with robust protection, smart design, and specialized inks. By ensuring consistent performance in the harshest environments, KGK Jet empowers paint manufacturers to maintain quality, traceability, and brand integrity with confidence.
