Plastisol ink is one of the most commonly used inks in the US for screen printing on fabrics. It is made up of a suspension of PVC particles in a liquid plasticizer. When the ink is heated, the plasticizer evaporates, and the PVC particles fuse together, forming a solid and durable film on the surface of the fabric. Plastisol ink is known for its excellent opacity and ability to produce bright, vivid colors on both light and dark colored fabrics. It is also resistant to fading, cracking, and peeling, making it a popular choice for custom printed clothing and other textile items.
