 Aluminium Paste Drives High-Gloss Metallic Ink Performance

The global printing inks market continues to shift toward high-value decorative effects.

According to Smithers Market Intelligence (2024), metallic and special-effect inks are growing at over 6% annually, driven by premium packaging and branding.

Aluminium paste enables this growth by offering a combination of optical brilliance, process stability, and cost efficiency.

How Aluminium Paste Creates High-Gloss Metallic Effects

Flake Orientation and Optical Reflection

The metallic gloss of aluminium paste is achieved through controlled flake geometry and alignment.

Key contributors include:

• Fine, smooth aluminium flakes

• Narrow particle size distribution

• Parallel flake orientation in the ink film

When printed, these flakes reflect light uniformly, resulting in:

• Mirror-like metallic gloss

• Strong brightness and coverage

• Clean, consistent metallic appearance

These optical principles are well established in printing ink and pigment science literature.

Performance Advantages in Printing and Processing

Printability, Stability, and Consistency

High-quality aluminium paste improves ink performance during printing by:

• Enhancing ink flow and levelling

• Reducing mottling and streaking

• Supporting consistent transfer in gravure, flexo, and screen printing

Properly surface-treated aluminium paste also improves storage stability and oxidation resistance, helping inks maintain performance over time.
