Heat is your enemy with performance fabrics  The more you heat the shirt, the worse the dye migration you are likely to encounter. Control the heat, use proper ink, watch your flash dwell times… and don’t hot stack the shirts at the end of the dryer.

Instead, use two or three piles and as the shirts travel down the belt add a new shirt to the next pile. Have a fan blow air on the shirts. All shirts should be cool to the touch before going into a box. Most dye migration problems occur long after your crew last reviewed them, as hot shirts in a box continue to activate the dye.

If your production manager ever says “But they looked great when they left here!” you can bet that they didn’t follow the procedure outlined above.
