As sustainability becomes a core value across industries, printers and manufacturers are seeking alternatives to traditional solvent-based inks. One of the most effective and eco-friendly solutions on the market today is aqueous ink—also known as water-based ink. But what exactly are aqueous inks, and why are they gaining popularity in commercial and industrial printing?

In this article, we’ll explore the definition, advantages, applications, and future trends of aqueous inks—and introduce how Starcolor is leading innovation in this space.

What Are Aqueous Inks?

Aqueous inks are a type of printing ink that uses water as the primary solvent or carrier, instead of petroleum-based chemicals. These inks typically contain:

• Water (as the carrier)

• Dyes or pigments (for color)

• Binders/resins (for adhesion)

• Additives (for flow, stability, and drying performance)

There are two main types of aqueous inks:

• Dye-based: Known for bright, vivid colors but less water-resistant

• Pigment-based: More durable and UV-resistant, ideal for outdoor or archival prints

Aqueous inks are commonly used in inkjet, flexographic, gravure, and textile printing, depending on the formulation.

Key Properties and How Aqueous Inks Work

Aqueous inks function by depositing colorants suspended in water onto a substrate. The water then evaporates or is absorbed into the material, leaving the colorant and resin behind. The ink film binds to the surface, resulting in a clean, vibrant, and stable image.

These inks require substrates that absorb moisture or special coatings to ensure proper adhesion and drying. In high-speed printing environments, forced air or heat is often used to accelerate drying.

Benefits of Aqueous Inks

🌱 1. Environmentally Friendly

• Low VOC emissions: Aqueous inks emit little to no volatile organic compounds (VOCs), making them safer for operators and compliant with environmental regulations.

• Non-toxic and biodegradable: Perfect for brands pursuing eco-labeling or green certifications.

🎨 2. Outstanding Print Quality

• High color vibrancy and clarity

• Smooth finishes with excellent dot definition and detail

• Ideal for packaging, fine art, and premium commercial applications

🛡️ 3. Safe for Sensitive Applications

• Suitable for food packaging, children’s products, and medical labels

• Compliant with global safety standards

⚡ 4. Cost-Effective in the Long Term

• Reduced need for solvent recovery systems

• Lower maintenance costs for machinery

• Extended printhead life in digital systems

Applications of Aqueous Inks

Aqueous inks are used in a wide variety of industries and substrates:

• Paper & Board: Magazines, books, paper bags, corrugated boxes

• Flexible Packaging: Pouches, films, and wrappers

• Textiles: Direct-to-garment (DTG) and direct-to-film (DTF) printing

• Labels & Stickers: Durable product labels, security tags

• Art & Graphics: Posters, fine art reproduction, photo prints

• Inkjet Printing: Commercial, industrial, and home printers

Aqueous Inks vs. Other Ink Technologies

Challenges & Considerations

While aqueous inks offer many benefits, they do have limitations:

• Limited adhesion on non-porous substrates (unless treated or coated)

• Water resistance may require post-coating or lamination

• Slower drying than UV or solvent in some conditions

• Not suitable for high-moisture environments without enhancements

However, ongoing innovation—especially in binders and coating chemistry—is closing these gaps quickly.

Trends Driving Aqueous Ink Adoption

• 🌍 Growing demand for sustainable packaging and compostable materials

• 🏭 Increased use in industrial inkjet systems (e.g. corrugated, textiles)

• 🔬 Advances in high-performance resins improving durability and water resistance

• 💡 Support from global brands focused on ESG and green printing solutions
