One of the biggest demands in the printing industry is athletic printing. Here are a couple of things to keep in mind when printing on a polyester fabric using low cure.
1. Dye migration:
This happens when a polyester fabric hits a certain temperature, usually between 300˚ and 310˚. At this temperature, the dye in the ink becomes gaseous and transfers its color to the ink of the fabric. Low cure lowers the curing temperature of the ink and allows you to avoid dye migration.
Tip: Polyester fabric heats up faster than other fabrics. So limit your curing time in addition to adding low cure, to make sure that you aren’t over-curing your garments.
2. Mesh:
In the video below, Josh uses a 110 mesh screen to print, but it isn’t a terribly picky process. You want to have a nice amount of ink to lay on the fabric, but not too much. Unlike water based ink, plastisol can have a heavier and chunky feeling, so printing with a higher mesh count can help you to eliminate some of the plastic-feeling.
Check out this video, and Josh can show you step-by-step.
