Prepare your polyester fabrics correctly to achieve optimal results. Here are essential steps:
| Step | Description |
|---|---|
| 1 | Wash the fabric to remove any contaminants. |

| 3 | Use a pre-treatment if necessary to enhance paste adhesion. |
As expert Maria Gonzalez emphasizes, "Clean surfaces are half the battle. Always start with freshly washed fabric for the best results."
3. Choosing the Right Dyestuffs
When using polyester screen printing paste, selecting the correct dyestuffs can significantly enhance prints' vibrancy and longevity. Based on consultations with style influencer Chloe Track, consider the following:

| Reactive Dyes | For bright, wash-fast colors on polyester. |
| Disperse Dyes | Ideal for achieving vivid shades with excellent durability. |

Choosing the right dyestuff not only enhances quality but also aligns with customers' demands for vibrant prints.

| Ingredient | Recommended Ratio |
