Polyester screen printing ink is a popular option in the printing industry because of its durability, versatility, and vibrant colors. This ink is commonly used for printing on synthetic fabrics such as polyester and nylon, due to their non-absorbent surfaces that require specialized ink to adhere properly. This article will guide you through the process of using polyester screen printing ink, explore its composition, and discuss its suitability for different types of fabrics.℃
What is Polyester Screen Printing Ink Made Of?
Polyester screen printing ink is typically composed of pigments, binders, solvents, and additives. The pigments are responsible for the ink's color, while the binders hold the pigments together and ensure they adhere to the surface of the fabric. Solvents are added to adjust the ink's viscosity, which determines how easily it flows through the mesh of the screen during printing.
Additives like catalysts and hardeners are also included in some polyester inks to improve their durability and resistance to abrasion, fading, and washing. Additionally, some inks contain special features such as metallic shimmer or glow-in-the-dark properties.
How to Use Polyester Screen Printing Ink
The following are some simple steps to follow when using polyester screen printing ink for your project:
Step 1: Prepare the Fabric
Make sure the fabric is clean, dry, and free of any dust, lint, or wrinkles that could affect the printing quality. If necessary, pre-treat the fabric with a coating to enhance its dye receptivity.
Step 2: Create the Design
Design the artwork you want to print and transfer it onto a transparency film. Depending on the complexity of the design, you may need to separate it into separate color layers.
Step 3: Coat the Screen
Coat the screen with a photo-emulsion or emulsion remulsion according to the manufacturer's instructions. Place the transparency film with the design on top of the coated screen and expose it to light to create the stencil. Rinse the screen with water to reveal the stencil pattern.
Step 4: Load the Ink
Squeeze a small amount of polyester ink onto the screen, near the bottom of the design area. Using a squeegee, spread the ink over the stencil, applying pressure to push the ink through the mesh and onto the fabric.
Step 5: Cure the ink
Once the printing is complete, the ink must be cured or dried to ensure it adheres firmly to the fabric. This can be done either by air-drying the ink or using a heat press or oven to cure the ink according to the manufacturer's instructions.
Is Polyester Screen Printing Ink Best for T-Shirts, Hoodies, and Shoes?
Polyester screen printing ink is ideal for printing on synthetic fabrics such as polyester and nylon, due to their non-absorbent surfaces that require specialized ink to adhere properly.
Polyester ink provides excellent color saturation, opacity, and durability, making it a popular choice for printing on t-shirts, hoodies, and shoes. However, it may not be the best option for all fabrics, especially those with a high percentage of natural fibers such as cotton, as the ink may not penetrate the fibers evenly and may fade quickly.
Can Silicone Ink be Printed on Polyester and Nylon?
Yes, silicone ink can be printed on polyester and nylon fabric. Silicone ink is a flexible ink that can adhere well to both natural and synthetic materials, making it an ideal choice for printing on garments and accessories that require flexibility, elasticity, or a soft touch.
Silicone ink is resistant to cracking, peeling, and fading, and can withstand extreme temperatures, making it a durable and long-lasting choice for printing on items like sportswear, swimwear, and footwear. Additionally, silicone ink can produce high-resolution images with excellent color vibrancy and accuracy.
In conclusion, polyester screen printing ink is a valuable tool in the printing industry, allowing for vibrant and long-lasting images on synthetic fabrics. Follow the steps above for proper use, consider your fabric choice, and give silicone ink consideration for printing on synthetic items.
