Metallic gold plastisol ink is a high-performance, specialty screen printing medium engineered to provide a vibrant, reflective metallic finish on a wide range of textile substrates. Unlike standard plastisol inks, metallic variants contain finely milled metallic particles—typically aluminum or bronze flakes—that give the ink its characteristic shimmer and shine. These particles are suspended within a PVC-based plastisol binder, which provides excellent coverage, adhesion, and durability on both light and dark fabrics.
This ink type is a top choice for apparel decorators seeking to achieve a premium visual effect without compromising wash durability or flexibility. When correctly applied and cured, metallic gold plastisol ink produces long-lasting, eye-catching prints that maintain their brilliance through repeated laundering and wear.

Key Properties and Functional Benefits
Metallic gold plastisol ink exhibits several defining features that contribute to its popularity in the screen printing industry:
1. Высокая прозрачность
One of the most significant advantages of this ink is its ability to offer superior opacity, especially on dark-colored garments. The high pigment and metallic flake load reduce the need for multiple print passes and ensure vibrant, saturated results with minimal ink buildup.
2. Metallic Particle Suspension
The reflective nature of the ink is achieved through the suspension of metallic flakes within the plastisol base. These particles are precisely sized to reflect light effectively, creating a bold shimmer effect that is highly visible and aesthetically appealing, especially under direct lighting.
3. Curing Requirements
For optimal performance, metallic gold plastisol ink must be heat-cured at temperatures between 270°F and 320°F (132°C to 160°C). Proper curing allows the PVC resin to cross-link and encapsulate the metallic particles, ensuring permanent adhesion to the fabric and wash resistance.
4. Post-Cure Flexibility
Despite its metallic content, the ink retains a flexible and soft feel when cured correctly. This flexibility prevents the ink from cracking or flaking off, even on stretchable or movement-intensive garments like sportswear and performance gear.
Common Applications
Thanks to its visual appeal and mechanical durability, metallic gold plastisol ink finds widespread use in multiple commercial and creative printing environments:
- Athletic and Team Apparel
Used for numbers, logos, and trims that need to stand out under stadium lights or during motion. - Fashion Textiles and Streetwear
Offers a striking accent on designer garments, often used in branding, trims, and statement graphics. - Рекламные товары
Ideal for giveaways, event apparel, and corporate branding where visual impact enhances product value. - Premium Labeling and Packaging
Frequently applied to tote bags, high-end garments, or accessory labels to reinforce a luxury identity.
Recommended Fabric Substrates
To ensure optimal performance, metallic gold plastisol ink is best suited for the following fabrics:
- 100% Cotton
Provides excellent ink adhesion and is the most common base for screen printing applications. - Cotton/Polyester Blends
Suitable with low-bleed formulations to prevent dye migration. - Performance or Synthetic Fabrics
With proper pretreatment, the ink can adhere well to polyester, nylon, or spandex, commonly used in athletic apparel.
Примечание: For synthetic fabrics, always test compatibility or use a blocker base if bleed-through or dye migration is a concern.
Product Variants and Recommended Uses
| Product Name | Key Features | Best Use Cases |
|---|---|---|
| Sunshine Metallic Ink | Brightest metallic finish; rapid curing | Sports apparel, attention-grabbing fashion |
| Dune Metallic Ink | Softer hand; medium reflectivity | Daily wear, blended textiles |
| Champagne Gold Ink | Subtle shimmer; smooth application | High-end fashion, fine fabrics |
Each of these options offers unique benefits in terms of hand feel, shine, and substrate compatibility, allowing decorators to tailor the ink to the intended design and fabric type.
Best Practices for Screen Printing
To achieve consistent, high-quality results, consider the following technical recommendations when printing with metallic gold plastisol ink:
- Screen Mesh Count: Используйте 90–125 mesh screen. A lower mesh count allows metallic flakes to pass through the mesh more freely, ensuring better flake deposition and reflectivity.
- Squeegee Hardness: А 70–75 durometer squeegee is ideal for even ink transfer without damaging finer design details.
- Print Pressure: Использовать medium to firm pressure. Avoid excessive force, which may distort fine lines or cause ink bleed.
- Условия затвердевания: Cure at 270°F (132°C) для at least 60 seconds. Ensure the full ink layer reaches the target temperature; use a laser or probe thermometer for accuracy.
- Underbase Use: When printing on dark garments, apply a white plastisol underbase to enhance brightness and metallic contrast.
- Ink Modifiers: To adjust viscosity or improve softness, consider using additives like a plastisol reducer или softener, based on fabric and desired finish.
Handling and Storage Guidelines
Maintaining ink quality and preventing contamination are critical to long-term screen printing success:
- Mix Before Use: Stir ink thoroughly before each session to re-suspend metallic flakes that may have settled.
- Условия хранения: Store in airtight containers at room temperature. Avoid extreme heat or cold, which can affect consistency.
- Avoid Cross-Contamination: Do not mix metallic and non-metallic inks unless specifically formulated for blending, as this can dull the finish.
- Clean Screens Promptly: Metallic particles can dry quickly within the mesh, so clean tools and screens immediately after use to prevent clogging and ink waste.
