Introduction to Polyester Screen Printing Ink

Polyester screen printing ink is specially designed for printing on polyester fabrics, offering superior adhesion, durability, and color vibrancy. Polyester fabrics are widely used in sportswear, fashion, and promotional items due to their lightweight and moisture-wicking properties.

Properties of Polyester Screen Printing Ink

• Adhesion: Ensures that the ink bonds effectively with polyester fibers.
• Opacity: High opacity is crucial for vibrant colors on darker fabrics.
• Elasticity: Allows printed designs to stretch with the fabric without cracking.
• Heat Resistance: Polyester fabrics often require heat setting, so the ink must withstand high temperatures.

Best Practices for Polyester Screen Printing

1. Select the Right Mesh Count:

   Choose a mesh count between 110 to 156, balancing ink deposit and detail retention.

2. Use Proper Emulsion:

   Employ an emulsion with a high solid content and water/solvent resistance.

3. Optimize Curing Temperature:

   Cure the ink at 320°F (160°C) to ensure durability without affecting the fabric.

4. Pre-Treat Polyester Fabrics:

   Use a poly blocker base to prevent dye migration from polyester garments.

5. Test Before Production:

   Always perform a test run to identify any potential issues with adhesion or color accuracy.

Common Challenges and Solutions

• Dye Migration:

  Prevent dye migration by using barrier inks or poly blockers.

• Curing Issues:

  Ensure the curing process is precise, using a temperature-controlled conveyor dryer.

• Ink Crackling:

  Adjust ink elasticity and ensure proper curing to avoid cracks.

• Registration Problems:

  Maintain accurate screen tension and alignment for consistent registration.
