Silk screen poly ink is a type of ink specifically formulated for screen printing on polyester fabrics. Polyester is a popular choice for clothing and other textile applications due to its durability, moisture-wicking properties, and resistance to wrinkles and shrinking. However, polyester can be a challenging material to print on due to its low absorbency and slick surface.

Polyester inks are designed to adhere well to polyester fibers and provide excellent color vibrancy and opacity. These inks are typically water-based or plastisol-based, depending on the desired printing effects and application requirements. Water-based poly inks are more environmentally friendly and offer a softer hand feel, while plastisol poly inks are more durable and provide a thicker layer of ink.

When using silk screen poly ink, it is important to properly prepare the fabric surface and use the correct mesh screen to achieve optimal results. The ink should be cured using heat to ensure proper adhesion and wash-fastness. Overall, silk screen poly ink is a versatile and reliable option for printing on polyester fabrics, offering vibrant colors and long-lasting results.
