Most inks will gel (flash) when the ink film reaches 220°F to 230°F. There are three factors that affect the gel or flash of the ink: the temperature of the flash, the distance of the flash from the printed image and the time the printed image is exposed to the heat. As a rule, you want to flash the ink film until it is just dry to the touch. Over flashing inks may cause adhesion problems and make the inks very tacky. Check your flash cure unit to see if it has temperature and airflow controls. This tends to be an approximate setting if the flash is at three-four inches above the garment (sweats require five-six inches), for eight-10 seconds. Some adjustments may be needed.
