1. Pick The Right Polyester

You need to know if there are many types of polyester blends. Each type of polyester blend has its characteristics. This depends on the fiber ratio because polyester mixed with other fibers can prevent the ink from absorbing properly.

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.

4. Address Ink Drying Concerns During The Flash Cure

As you know, the dye may migrate before the final curing process. This happens because you overheat the fabric under the flash curing process.

Flash your image to the substrate only as long as the image needs to be cured. Then, the temperature tape will assist you in measuring the temperature of your fabric on the conveyor dryer as well as under the flash cure.

Alternatively, you can use a permanent synthetic fixer, which is useful for ink sets that are difficult to adhere to polyester. Therefore, to avoid color bleeding, you must test the ink on the fabric of your choice.

5. Use a Slip Sheet During the Heat Process

During the applications and curing processes, polyester requires the use of slip sheets to keep your artwork flat. This is because polyester is a synthetic fiber. In addition, you can place the slip-sheet under your design inside the garment before you print it.

That’s an interesting review about screen printing on polyester that you should know. You can apply all of this information when you want to screen printing using polyester. Then, do it carefully to produce high-quality screen printing.
