There are two main types of ink that are used for textile printing, water-based ink and plastisol.

Plastisol ink is a PVC (polyvinyl chloride) based system that essentially contains no solvent at all,

it is a thermoplastic ink in that it’s necessary to heat the printed ink film to a temperature high

at is the range of enough to cause the molecules of PVC resin and plasticizer to cross-link and thereby solidify, or cure.

The temperature for most plastisol for textile printing cure at is the range of 149°C to 166 °C (300°F to 330°F).

Now we introduce some characteristics for both of them:
