Understanding Metallic Pigments for Printing Inks

Metallic pigments in printing inks combine fine metal flakes with optimized surface treatments to achieve high reflectivity and stable dispersibility.

Aluminum paste and bronze powder are two of the most widely used materials.

These pigments enable printers to achieve metallic sheen, high opacity, and excellent coverage with minimal usage—crucial for cost-effectiveness and visual appeal.

Aluminium Paste for Printing Inks

Aluminium paste is valued for:

• Clean silver-white metallic brilliance

• Smooth laydown and leveling

• High reflectivity

• Compatibility with multiple printing systems (gravure, flexo, offset, screen)

At ZHANGQIU METALLIC PIGMENT, our ink-grade aluminium paste is engineered for:

1. Stable Dispersion

Thanks to controlled particle size distribution and surface treatment, our aluminium flakes disperse quickly and uniformly in varnishes and ink vehicles.

2. High Gloss & Mirror Effect

Fine particle aluminium flakes create sharp reflectivity—ideal for premium labels, cosmetics packaging, and high-end print designs.

3. Excellent Printability

Consistent viscosity and narrow particle size ensure smooth printing at high speeds.

Bronze Powder (Copper-Gold Powder) for Inks

Bronze powder remains the top choice for gold-appearance prints.
ZHANGQIU METALLIC PIGMENT supplies bronze powder in various shades, including:

• Rich Pale Gold

• Rich Gold

• Rich Red Gold

• Rich Copper

1. Warm Metallic Aesthetic

Bronze pigments provide warmer tones compared with aluminium paste, making them ideal for luxury branding.

2. Strong Chemical Stability

Our powders include optimized antioxidant treatment to resist tarnishing during ink storage and printing.

3. Adjustable Particle Fineness

Printers can choose fine grades for smooth metallic sheets or coarse grades for high-texture effects.

FAQ

1. Why does aluminium paste sometimes cause gas generation in inks?

This usually occurs when aluminium reacts with moisture.
Solution: Use low-moisture varnishes and select resin-coated or SiO₂-treated grades.

2. Can bronze powder oxidize in storage?

Rarely—with proper antioxidant treatment. Store in a cool, dry environment for best performance.

3. Are metallic pigments suitable for water-based inks?

Yes—our waterborne aluminium series uses special coatings to prevent water reaction.

4. How important is particle size control?

Critical. Finer flakes produce smooth mirror effects; coarser flakes offer sparkle and texture.
