DTF White Ink Solution: The Core Guarantee for High-Quality Printing at Hanrun Paper Industry

DTF white ink is a critical material in the Direct-to-Film (DTF) printing process. It is primarily used to create a white base layer on transfer films, enabling vibrant and accurate image reproduction on dark fabrics.

However, in industrial DTF applications, white ink is far more than just “white color.”
It is a functional foundation material that directly determines color accuracy, adhesion, and final print durability.

At the same time, even high-performance white ink cannot deliver optimal results without proper system compatibility.
Film, powder, equipment, and software must work together as an integrated system.

A System-Level Approach from Hanrun

With over 14 years of experience in transfer materials, Hanrun focuses on solving one of the most common challenges in the industry:
inconsistent performance caused by mismatched consumables.

Instead of supplying standalone materials, Hanrun provides a fully integrated solution:

• Printer
• Original ink
• Specialized DTF film
• Hot-melt adhesive powder
• Color management software

All components are engineered and tested as a complete system.

This approach eliminates compatibility issues and avoids the common problem of unclear responsibility between suppliers—ensuring stable and predictable production for our customers.

1. Composition and Key Properties

Hanrun DTF white ink is a water-based pigment ink optimized for DTF systems.
Its formulation includes:

• High-concentration white pigment (typically titanium dioxide)
  Provides excellent opacity and coverage
• Water-based carrier
  Low odor, environmentally friendly, and easy to clean
• Polymer resins and functional additives
  Enhance adhesion to DTF film coatings and ensure strong bonding with hot-melt powder

Hanrun white ink and its corresponding adhesive powder are manufactured using environmentally compliant materials and are certified under OEKO-TEX® Standard 100, ensuring safety for skin contact and compliance with global environmental standards.

2. Product Series

To meet different application requirements, Hanrun offers two product lines:

• EVO DTF White Ink
  Balanced performance with good flexibility and color output, suitable for general production
• PRO DTF White Ink
  Enhanced sharpness and color saturation, designed for high-end customization and detailed graphics

Both series are validated through system-level testing to ensure stable compatibility across equipment and consumables.

3. Role in the Printing Process

DTF white ink performs several critical functions:

• Base Layer Formation
  Creates a white underlayer that isolates dark fabric backgrounds and ensures accurate color reproduction
• Color Support
  Provides a stable base for CMYK inks, resulting in brighter and more saturated colors
• Bonding Medium
  Works in coordination with film and adhesive powder to form a durable layer after heat curing, directly affecting adhesion and wash resistance

This stage requires a high level of ink stability—one of the key areas of Hanrun’s continuous optimization.

4. Application and System Matching

• Standard Configuration
  White ink (W) is essential in CMYK+W printing systems
• System Compatibility
  For optimal results, a fully validated system (printer + ink + film + software) is recommended
• Sedimentation Control
  Due to high pigment density, white ink may settle over time.
  Advanced equipment (e.g., EVO A-600) is equipped with automatic circulation systems to maintain ink consistency

Hanrun strongly recommends using verified system combinations to reduce failure rates and ensure production stability.

5. Production Stability and Technical Support

To ensure consistent performance:

• Daily Maintenance
  Perform nozzle checks before operation; if idle for more than two days, keep printheads properly moisturized
• Ink Circulation
  Activate white ink circulation systems daily to prevent sedimentation
• Storage Conditions
  Store at 10–30°C and 35–65% humidity; follow FIFO (First-In, First-Out) principles

Hanrun maintains strict batch control and quality assurance processes to minimize the impact of environmental variations.

Conclusion

Selecting DTF white ink is not just choosing a consumable—it is choosing the foundation of the entire printing system.

With its integrated solution approach, strict quality standards (including OEKO-TEX® certification), and responsive global service network, Hanrun ensures reliable performance at every stage—from ink to final output.
