There are two types of ink being utilized in the screen printing industry: water-based ink and Plastisol. While water-based ink is used frequently for all-over and large format printing, Plastisol is most commonly used to print finished goods such as T-shirts, sweatshirts, jackets, and tote bags. Manufactured by a number of companies, Plastisol is a suspension of polyvinyl chloride (PVC) particles in a plasticizer, an additive that increases plasticity or fluidity.

Plastisols are especially useful when printing opaque graphics on dark fabrics. In addition, Plastisol heat transfers are often utilized on fabrics. The mastery of all the technical requirements of Plastisol is essential to providing top quality screen printing products. The main technical requirement is that Plastisol must be “cured” or dried with heat after printing. The temperature at which most Plastisol cures ranges from 300° to 330° F. Plastisol inks do not act like dye, which is deposited onto the surface of the fabric, but instead wrap around fibers, creating a mechanical bond with the fabric. Other notable features of Plastisol inks:

1. Not Water-Soluble
2. Excellent Washability
3. Will Adhere to Most Textiles, 100% Cotton is Best
4. Contains No Air-Polluting Solvents or Volatile Organic Compounds
5. Slight Flammability Rating of 1, Reactivity Rating of 0
6. Comes in Strengths from Transparent to Very Opaque
7. Cured Ink is Not Considered Hazardous Waste
8. High Quality Plastisol Provides Soft Hand and Good Opacity
9. Special Effects, such as Puff, Glitter, Metallic and So On
