What is Pigment?

A pigment is a solid colour particle that does not dissolve in liquid. Instead, it is suspended within an ink or binder. When applied to fabric during printing, the binder holds the pigment in place after curing.

In garment printing, pigment-based inks are commonly used because they provide strong colour, good coverage, and compatibility with various fabrics. The pigment itself provides the colour, while the binder ensures adhesion and durability.

Unlike reactive dyes used in dye sublimation, pigments do not penetrate deeply into the fibres. They remain on the surface layer of the fabric.

How Pigment Works in Apparel Printing

Surface-Level Colour Application

Pigment-based inks coat the top layer of the fabric. Once heat-cured, the binder forms a thin film that locks the pigment particles in place. This makes pigment printing suitable for cotton and cotton-blend garments.

Because the colour sits on the surface, the print appearance can vary depending on fabric texture and weave.

Compatibility with Multiple Fabrics

One advantage of pigment inks is their versatility. They can be used on cotton, polyester blends, and even some specialty fabrics. This flexibility makes pigment printing suitable for a wide range of applications in the Australian custom apparel market.

Colour Opacity and Coverage

Pigments provide strong opacity, especially when combined with the right ink formulation. This is particularly important when printing light colours on dark garments. A proper underbase layer may be required to achieve optimal brightness.

Benefits of Pigment-Based Printing

Reliable Colour Performance

Pigment inks are known for consistent and predictable colour results. When matched correctly, they can reproduce brand colours accurately across multiple production runs.

For businesses requiring uniform branding across workwear or promotional garments, this consistency is critical.

Good Wash Durability

When properly cured, pigment prints hold up well under normal washing conditions. The binder secures the pigment particles, helping to resist fading and cracking.

Durability depends on correct curing temperature, garment quality, and washing practices. Professional printing processes ensure long-lasting results.

Cost-Effective Production

Pigment-based inks are widely used in screen printing because they are efficient for bulk production. For medium to large runs, pigment inks offer strong performance at competitive pricing.

This makes them a practical option for:

• Corporate uniforms
• Event merchandise
• School apparel
• Promotional campaigns

Pigment vs Dye in Garment Printing

While both pigments and dyes create colour, they function differently.

Pigments:

• Sit on top of the fabric
• Require a binder
• Work well on cotton and blends
• Offer strong opacity

Dyes:

• Penetrate fabric fibres
• Chemically bond with the material
• Are commonly used in dye sublimation
• Work best on polyester

For example, dye sublimation is ideal for full-colour polyester sportswear, while pigment-based screen printing is preferred for cotton workwear and promotional T-shirts.

Applications of Pigment in Custom Apparel

Pigment inks are commonly used in:

• Screen printing
• Water-based printing
• Vintage or washed effects
• Large logo applications
• Multi-colour garment branding

They are particularly effective for bold graphics and corporate branding where opacity and durability are priorities.

In Australia’s custom garment industry, pigment-based inks remain one of the most reliable solutions for cotton apparel.

Practical Considerations

Fabric Selection

Pigment printing performs best on cotton and cotton-rich blends. The natural fibres allow the binder to adhere effectively. On synthetic-heavy fabrics, alternative ink systems may produce better results.

Print Feel

Because pigment sits on the surface, the print can feel slightly textured depending on ink thickness. Water-based pigment systems can offer a softer finish compared to traditional plastisol formulations.

Environmental Factors

Many modern pigment inks are available in eco-friendly, low-VOC, or water-based formulations. This aligns with growing sustainability expectations within the Australian apparel market.

Businesses seeking environmentally conscious production options often explore advanced water-based pigment systems.

Durability and Care

Proper curing is essential for pigment durability. If under-cured, prints may fade or wash out prematurely. Commercial garment printers use controlled heat settings to ensure optimal bonding.

To maximise longevity:

• Wash garments inside out
• Use cold water
• Avoid high heat tumble drying
• ​​​​​​​Do not iron directly over prints

When maintained correctly, pigment prints can retain their appearance for the life of the garment.

Conclusion

Pigment is a core component of many custom garment printing methods. As a surface-level colour particle held in place by a binder, it provides strong opacity, reliable performance, and compatibility with a wide range of garments.

For Australian businesses investing in uniforms, promotional apparel, or branded merchandise, pigment-based printing offers a balanced solution combining durability, colour consistency, and production efficiency.

Understanding how pigment works allows brands to choose the right printing method for their fabric, design complexity, and long-term performance expectations.
