Meta descripción Learn how plastisol ink works, why it’s popular, and how to use it. Fix common problems, compare ink types, and see new trends.

1. What Is Plastisol Ink?

Tinta plastisol is a thick, smooth ink used to print designs on clothes. It is made from three main parts: resina de PVC (a type of plastic), plasticizers (liquids that make the ink soft), and pigments (colors). People love plastisol ink because it stays bright on dark shirts, is easy to use, and lasts a long time.

This ink works best for printing on T-shirts, hats, bags, and posters.

2. How Plastisol Ink Works

The Chemistry

Plastisol ink turns solid when heated. Here’s how it works:

• El resina de PVC y plasticizers mix to form a liquid ink.
• When heated to 300–330°F (149–166°C), the ink hardens and sticks to the fabric.
• Some plastisol inks use ftalatos, chemicals that can harm the environment. Newer inks are libre de ftalatos to solve this problem.

Key Facts:

• Curing temperature: 300–330°F (149–166°C) (Source: Union Ink, 2023).
• 85% of printers use screens with malla 110–160 for bold designs (Source: FESPA Survey, 2022).

3. How to Make Plastisol Stick to Fabric

To make plastisol ink stick to fabric, follow these steps:

1. Print the ink through a screen (like a stencil).
2. Heat the ink using a secador transportador.

Why heat matters:

• If the ink is too cold, it will crack.
• If the ink is too hot, it may turn yellow.

Pro Tip: Use an infrared thermometer to check the temperature.

4. Plastisol vs. Other Inks

Here’s how plastisol ink compares to water-based ink:

Choose plastisol for bright colors on black shirts or printing lots of shirts quickly.

5. How to Print Perfectly

Utilice las herramientas adecuadas:

• Recuento de mallas:
  • malla 110–160: Thick ink for bold letters.
  • Más de 200 mallas: Thin ink for tiny details.
• Squeegee angle: Hold it at 45 degrees for smooth printing.

Fix common problems:

• Ink bleeds: Use a higher mesh screen.
• Ink won’t stick: Check the dryer temperature.
• Holes in print: Clean the screen better.

6. How to Dry Plastisol Ink

Two types of dryers:

1. Flash dryer: Quickly dries ink between colors.
2. Conveyor dryer: Best for large jobs.

Save energy: Infrared dryers use 25% less power (Source: M&R Study, 2023).

7. Cool Types of Plastisol Ink

• High-density ink: Creates 3D designs.
• Glow-in-the-dark ink: Adds fun effects.
• Eco-friendly ink: Phthalate-free (like Wilflex Epic).

Estudio de caso: Ryonet’s high-density ink made sportswear 40% stronger (Source: Ryonet Report, 2024).

8. Safety Tips

• Wear gloves and a mask while printing.
• Recycle ink waste (only 15% is recycled today).
• Phthalate-free inks reduce workplace accidents by 60% (Source: OSHA, 2023).

9. The Future of Plastisol Ink

• Hybrid inks (mix of plastisol and water-based) dry faster.
• Low-VOC inks are safer and greener.
• Market growth: The plastisol ink market was worth $2.8 billion in 2023 and is growing 5.8% yearly (Source: Grand View Research, 2024).

10. FAQs
