When working with an Econocure 6100 to print on Gildan 2000 shirts using white plastisol ink, achieving the right settings is crucial for ensuring a high-quality finish. This guide provides a step-by-step approach to determining the optimal belt speed and gate height settings, helping you avoid common pitfalls and ensuring your prints cure correctly.

Step 1: Understanding the Basics

Plastisol ink requires a curing temperature of approximately 320°F. Ensuring the ink reaches this temperature is essential for a durable print. The belt speed and gate height on the Econocure 6100 dryer play a significant role in this process.

Step 2: Initial Setup and Temperature Checking

1. Set Initial Belt Speed and Gate Height:
   • Start with a moderate belt speed. This setting will serve as a baseline for adjustments.
   • Adjust the gate height so that the shirts pass through without touching the gate. Typically, you need to readjust this when switching between different types of garments, such as from t-shirts to hoodies.
2. Perform a Temperature Test:
   • Place a blank Gildan 2000 shirt on the belt and run it through the dryer.
   • Use a temperature gun to measure the ink’s temperature at the center of the dryer. The goal is to reach at least 320°F.

Step 3: Adjusting Belt Speed

If the ink does not reach 320°F:

• Increase the Belt Speed: If the temperature exceeds 320°F, the shirt is curing too quickly. Increase the belt speed slightly to reduce the exposure time.
• Decrease the Belt Speed: If the temperature is below 320°F, decrease the belt speed. This allows the shirt more time in the dryer to reach the necessary curing temperature.

Step 4: Multiple Passes

For shirts that do not reach the desired temperature on the first pass:

• Send the Shirt Through Again: There’s no harm in running the shirt through the dryer multiple times. This method ensures that the ink cures properly without damaging the shirt.

Step 5: Fine-Tuning and Consistency

Once you find the optimal belt speed and gate height:

• Maintain Consistency: For regular t-shirts, you won’t need to adjust the settings often. Only modify the settings for different materials or when printing on garments like hoodies.
• Periodic Checks: Regularly check the temperature to ensure consistent curing, especially when changing to new ink batches or shirt types.

Troubleshooting Common Issues

• Ink Smudging: This can occur if the belt speed is too high or the ink hasn’t cured properly. Slow down the belt speed and check the temperature.
• Gate Height Adjustment: Ensure the gate height is adjusted to accommodate different garment types without touching the gate.

Conclusion

By following these steps, you can optimize the settings on your Econocure 6100 for printing on Gildan 2000 shirts with white plastisol ink. Conducting temperature checks and making incremental adjustments will help you achieve the best results without wasting materials.
