Understanding Screen Printing Ink Plastisol
Screen printing ink plastisol has become a cornerstone of the printing industry due to its versatility, durability, and ease of use. Unlike other types of screen printing inks, plastisol stands out for its ability to produce vivid, long-lasting prints that resist cracking and fading. Its composition and unique properties make it a popular choice for apparel and other textured surfaces.
This article explores what makes plastisol ink unique, how it compares to other inks like water-based inks, and why it is often the go-to option for professional printers worldwide.
What is Screen Printing Ink Plastisol?
Plastisol screen printing ink is a PVC-based ink that requires heat curing to bond with fabric or other materials. Unlike other inks, plastisol doesn’t dry until heat is applied, making it ideal for prolonged printing sessions without the risk of ink drying on the screen.
This unique ink formulation consists of two key components:
- PVC resin – Provides the body and structure.
- Plasticizer – Offers flexibility and allows the ink to flow smoothly.
The result is a highly durable print that maintains vibrancy and resists wear even after repeated washing. Brands like Wilflex Plastisol Ink have elevated the quality and consistency of plastisol inks, making them a favorite among professional screen printers.
Plastisol Ink vs. Water-Based Ink: A Comparison
When comparing plastisol ink vs. water-based ink, several differences arise that influence the choice of ink depending on the project.
1. Composition and Properties
- Plastisol Ink: Made from PVC and plasticizers; it does not air dry, requiring heat curing.
- Water-Based Ink: Comprised of pigments suspended in water; it air-dries naturally or with low heat.
2. Ease of Use
Plastisol is more forgiving for beginners as it doesn’t dry out on the screen, allowing more time to correct mistakes. Water-based inks, on the other hand, can clog screens if not used quickly, making them less ideal for intricate designs.
3. Environmental Impact
Water-based inks are more eco-friendly, as they are free of harmful chemicals. However, innovations in plastisol formulations, such as phthalate-free Wilflex Plastisol Ink, have reduced its environmental footprint significantly.
4. Application and Durability
Plastisol ink shines when printing on dark garments, as its opacity ensures vibrant colors. Water-based inks, while softer to the touch, can struggle with opacity on dark fabrics. Plastisol prints last longer and resist cracking, making them perfect for workwear and promotional apparel.

How to Cure Plastisol Ink for Optimal Results
Curing is a crucial step in the plastisol screen printing process. Proper curing ensures the ink bonds permanently to the substrate, providing a durable, wash-resistant print.
Recommended Curing Process:
- Set the Temperature: Plastisol ink typically cures at 320°F (160°C).
- Use a Conveyor Dryer: This ensures even heat distribution across the print.
- Perform a Stretch Test: After curing, gently stretch the fabric to check if the ink cracks. If it does, re-evaluate the curing process.
Investing in proper curing equipment, like flash dryers or conveyor dryers, is essential for achieving professional-grade results with screen printing ink plastisol.
Common Challenges with Plastisol Ink and Solutions
Like any material, plastisol ink has its challenges. Here are some common issues and how to overcome them:
1. Ink Build-Up on Screens
- Issue: Plastisol ink can build up on screens during long print runs.
- Solution: Clean screens regularly using an appropriate screen wash.
2. Poor Adhesion to Fabrics
- Issue: If not cured properly, the ink may peel off.
- Solution: Always monitor curing temperatures and times.
3. Thick Ink Consistency
- Issue: Thick ink may not flow smoothly, affecting print quality.
- Solution: Use an ink reducer to achieve a smoother texture without compromising opacity.
Plastisol Ink vs. Water-Based Ink: Which is Better?
The debate between plastisol ink vs. water-based ink ultimately depends on the specific needs of your project.
- Choose Plastisol Ink for:
- High-opacity prints on dark garments.
- Long-lasting, durable designs.
- Projects requiring vibrant colors.
- Choose Water-Based Ink for:
- Eco-friendly printing.
- Soft, breathable designs on light fabrics.
- Low-volume, artisanal projects.
While both inks have their strengths, screen printing ink plastisol remains the industry standard for commercial printing due to its unmatched versatility and reliability.
