Comparing Water-Based and UV Inks in Gravure Printing

As the gravure industry shifts toward sustainable and high-performance solutions, water-based and UV-curable inks have become leading alternatives to traditional solvent-based systems. Both reduce environmental impact, but their characteristics suit different applications.

Water-Based Inks

Advantages:

• Low VOC emissions – Water replaces most organic solvents, improving air quality and safety.

• Eco-friendly and compliant – Ideal for food packaging and brands focused on ESG goals.

• Stable color performance – Modern formulations ensure good printability and adhesion.

• Non-flammable – Safer for production environments.

Limitations:

• Higher drying energy – Requires efficient hot-air systems.

• Material sensitivity – Best on paper or treated films.

• Environmental factors – Humidity control is essential for consistent quality.

UV-Curable Inks

Advantages:

• Instant curing – Solidifies under UV light, eliminating drying tunnels.

• High gloss and durability – Excellent for premium, scratch-resistant prints.

• Zero VOC emissions – Meets strict air quality regulations.

• Compact production setup – Reduces line footprint and energy use.

Limitations:

• Higher initial investment – Requires UV curing systems.

• Not ideal for food contact – Needs certified low-migration formulations.

• Curing control – Precise UV calibration is necessary for quality results.
