Pigments Powder for Printing Inks
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Precision Colorants for the Global Ink Industry
Deqing Demi Pigment Technology Co., Ltd. provides specialized inorganic powders for the manufacturing of industrial and decorative printing inks. Our pigments are chosen for their purity and narrow particle size, which are essential for maintaining stable ink viscosity and preventing nozzle clogging. We support ink formulators in creating vibrant, durable colors for everything from outdoor signage to high-end packaging, ensuring that the final print maintains its integrity under exposure to UV light and environmental pollutants.
Printing Ink Application Fields
- Gravure & Flexo: High-opacity pigments for flexible packaging and labels.
- Screen Printing: Durable coloring for textiles, glass, and electronic panels.
- Inkjet Inks: Sub-micron pigments for wide-format outdoor advertising.
- Security Inks: Unique inorganic markers for brand protection and anti-counterfeiting.
Ink Grade Technical Data
| Property | Standard Value | Unit |
| Average Particle Size (D50) | 0.2 - 0.5 | μm |
| Oil Absorption | 25 - 35 | g/100g |
| Hegman Fineness | 7.5 - 8.0 | Units |
| Viscosity Impact | Low/Stable | Internal Method |
| pH Value | 6.0 - 8.0 | ISO 787-9 |
Attributes for High-Speed Printing
- Minimal Abrasivity: Low hardness profile protects printing plates and anilox rollers.
- Fast Dispersion: Rapidly develops full color strength in bead mills.
- UV Stability: Ideal for outdoor signage; will not fade or shift hue.
- Solvent Resistance: Completely stable in alcohols, esters, and hydrocarbons.
Q: Can these be used in water-based flexo inks?
A: Yes, we provide surface-treated grades that are easily dispersed in water-acrylic resins with excellent foam control.
Q: Are they suitable for food packaging?
A: We offer high-purity grades that comply with food packaging ink regulations regarding heavy metal migration.
Custom Ink Formulations
We provide "Press-Ready" pigment data to help formulators calculate the exact pigment loading for target optical density.
Micronization Services: For high-end inkjet applications, we offer specialty milling to achieve particle sizes below 300nm, ensuring maximum transparency and stability against sedimentation.
The Science of Optical Density
Color science in printing focuses on "Transparency" and "Optical Density." We use the Beer-Lambert law to optimize the particle concentration for maximum light absorption. By measuring the spectral reflectance on different substrates (white vs. black), we ensure that the pigment provides consistent color regardless of the backing material. We monitor the Delta E using the CIELab system to ensure that brand colors remain identical across different printing runs and substrates.
