Screen Printing on Polyester, 5 Great Tips That You Should Know

Therefore, you must have the right polyester blend for your needs. For example, you can use 100% polyester blends that cure ink very well. While polyester blends of less than 65% often cause curing problems.

2. Choose The Right Dye

Screen printing on polyester is possible, but you also need to choose the right type of ink for your purposes. There are various types of ink for screen printing, for example, plastisol ink, which is synthetic and bright.

Meanwhile, water-based inks are softer to the touch and more environmentally friendly. This is because the water-based ink is easier to absorb into the fabric, while the plastisol ink only sits on top of it so that it has a stiff feel.

If you are using polyester, to prevent dye migration, start with a thin layer of low-bleed or no-bleed ink. Then, polyester is resistant to absorbing moisture so you should use an under base if you use water-based inks.

3. Use an Underbase for Light or Dark Fabric

Different inks work differently on dark or light fabrics. Therefore, you should use an under base depending on the polyester color you choose. For example, you can prevent dye migration by using a single layer of gray or white under the base.

When you put them under the base, the plastisol color can be more easily applied to it. On the other hand, the gray underbase will be thicker and dry faster at lower temperatures so that it can slow down the migration of the dye.
