Applications of Water-Based Ink in Industrial Manufacturing

Our water-based ink plays an integral role in various industrial manufacturing sectors, supporting compliance with rigorous regulations while delivering consistent performance across downstream processes. Below are focused application scenarios, each defined by specific production environments, formulation methods, processing workflows, and end-use requirements.

1. Flexible Packaging Printing

Water-based ink meets the evolving demands of flexible packaging converters who require high-speed print runs with reduced VOC emissions. The ink offers reliable adhesion and fast drying on non-porous substrates such as BOPP, PET, and PE films, making it a preferred component in food-safe packaging systems where regulatory compliance and print clarity remain critical.

Industry compliance standards

• EU Framework Regulation (EC) No 1935/2004 on materials intended to come into contact with food
• Swiss Ordinance on Materials and Articles (SR 817.023.21, Annex 10 on printing inks)
• US FDA 21 CFR 175.105 for indirect food additives: adhesives and components of coatings
• China GB 9685 Standards for inks used in food packaging

Typical usage ratio

• 12–20% ink solids in total ink formulation; film weight adjusts between 0.6–1.0 g/m² depending on substrate and print method

Downstream process integration

• Direct addition to gravure or flexographic printing press reservoirs; viscosity adjusted inline for each press speed and substrate type
• Integration with solvent recovery units and closed-loop wash systems for environmental compliance

Final product types

• Snack food bags, frozen food pouches, confectionery wrappers, beverage sachets, stand-up pouches for detergents

2. Corrugated Board and Carton Printing

The formulation ensures high rub resistance and vivid color reproduction on absorbent paper-based substrates, serving high-volume corrugated box and folding carton producers. The water-based system minimizes press-side adjustments and reduces downtime during job changes, supporting high-throughput production lines for e-commerce and consumer goods packaging.

Industry compliance standards

• FSC Chain-of-Custody controlled materials (for secondary packaging)
• ISO 12647-6:2012 Process control in printing – Part 6: Flexography
• REACH Regulation (EC) No 1907/2006 for restricted substances

Typical usage ratio

• 9–15% ink concentrate in finished ink pot, adjusted by board type and required color strength

Downstream process integration

• Pumped directly into inking units on flexographic presses with automated viscosity and pH control
• Inline drying tunnels set for water removal and rapid setting with high air movement

Final product types

• Printed shipping cartons, shelf-ready display boxes, e-commerce mailers, beverage multipacks, custom folding cartons

3. Textile Printing (Screen and Digital)

This ink supports textile printers seeking formaldehyde-free, washfast prints with precise color matching for apparel, promotional, and home textiles. Manufacturers favor water-based formulations for their soft hand-feel and after-print durability, meeting expanding eco-labeling and workplace safety requirements.

Industry compliance standards

• OEKO-TEX® Standard 100 (Class I & II for baby and skin-contact textiles)
• ZDHC MRSL Conformance (Zero Discharge of Hazardous Chemicals Manufacturing Restricted Substances List)
• REACH Annex XVII and SVHC compliance

Typical usage ratio

• 15–25% water-based ink in total print paste; loading tailored to fabric absorbency and image coverage

Downstream process integration

• Added directly to screen- or digital-printer reservoirs; precise rheology control for mesh or printhead compatibility
• Post-print heat curing or infrared drying units to fix dyes and resins on fiber surface

Final product types

• T-shirts, sportswear, bedsheets, tote bags, promotional bandanas, retail fashion accessories

4. Paper and Paperboard Publishing

Print houses specializing in mass production of books, brochures, and magazines rely on water-based ink for its rapid drying, dot gain control, and compliance with major eco-certifications. The blend provides high opacity and minimized feathering on coated and uncoated stocks, allowing publishers to meet sustainability and workplace safety goals.

Industry compliance standards

• Blue Angel (DE-UZ 195, ecological criteria for printing products)
• Nordic Swan Ecolabel for printed matter
• ISO 2846-1:2006 (Color and transparency for offset inks)

Typical usage ratio

• 10–18% in final ink mixture; lowered for lightweight stocks or increased for large image areas

Downstream process integration

• Fed into offset or flexo inking systems, matched to sheet-fed or roll-fed presses by viscosity adjustments
• Utilization of high-speed air-knife and IR drying at press exit to maintain print line speed

Final product types

• School textbooks, paperback novels, advertising leaflets, product catalogs, children’s coloring books

5. Wallpaper and Decorative Paper Coatings

Producers of decorative wallcoverings and specialty papers use water-based ink for precise color effects, low emissions, and compatibility with diverse coating techniques. The product is formulated for rich pigment loading and resistance to abrasion and household cleaners, which is essential for durable, design-centric applications.

Industry compliance standards

• EN 233 Wet-scrub resistance for finished wallcoverings
• ISO 105-X12:2016 (Fastness to rubbing for printed paper)

Typical usage ratio

• 14–22% ink by weight in final print or coating formulation, customized for coverage and gloss requirements

Downstream process integration

• Metered into gravure or rotary screen coaters with controlled rheology for pattern application
• Thermal drying and embossing applied post-print for texture and finish

Final product types

• Premium wallpaper rolls, luxury gift wrap sheets, pre-coated décor panels, scratch-resistant laminated papers

6. Stationery and Office Supply Printing
