The printing industry has made significant progress toward sustainability, and water-based inks have become a key driver of that change. Compared with solvent-based systems, they release far fewer volatile organic compounds (VOCs) and support cleaner, safer production environments.
However, simply switching to water-based ink isn’t enough — how we handle, store, and maintain these inks also plays a crucial role in reducing environmental impact and improving overall efficiency.
1. Optimize Ink Usage and Mixing
Accurate ink management minimizes waste and prevents unnecessary disposal.
Use precise color matching systems to mix only the required volume.
Maintain proper viscosity control — over-thinning ink increases drying energy and reduces print quality.
Reuse return ink whenever possible, ensuring it remains within quality standards.
Efficient ink management means less waste, lower costs, and fewer resources consumed.
2. Improve Drying Efficiency
Although water-based inks are safer, they require more energy to dry.
Use energy-efficient drying systems such as variable-speed hot air or IR-assisted dryers.
Optimize air temperature and flow — excessive heat not only wastes energy but may affect substrate performance.
Regularly clean nozzles and ducts to maintain drying efficiency.
Reducing energy use directly cuts both costs and carbon footprint.
3. Handle Wastewater Responsibly
Wastewater from cleaning and ink residue can still contain pigments and additives.
Collect and treat cleaning water before discharge — never pour it directly into drains.
Use closed-loop cleaning systems that filter and reuse wash water.
Partner with certified waste handlers for proper disposal and recycling.
Responsible wastewater management ensures compliance and protects local ecosystems.
4. Maintain Proper Storage and Shelf Life
Water-based inks are sensitive to temperature, contamination, and evaporation.
Store in a cool, stable environment away from direct sunlight.
Keep containers sealed tightly to prevent skinning and microbial growth.
First In First Out (FIFO) to reduce ink expiry and waste.
Good storage practices extend ink life and prevent unnecessary disposal.
5. Train and Engage Your Team
Environmental progress depends on awareness at every level.
Train operators on correct ink mixing, storage, and waste handling.
Encourage a sustainability mindset — small habits like labeling containers or using reusable tools make a difference.
Track key environmental metrics (VOC reduction, waste volume, energy use) to show real progress.
An informed team is the foundation of sustainable production.
Toward a Greener Future
Water-based inks represent a major step toward cleaner printing — but true sustainability comes from continuous improvement in every aspect of handling and operation.
By combining responsible ink management, energy efficiency, and team awareness, printers can achieve high-quality results while meeting global ESG and carbon reduction goals.
