Having some issues with my Geo Knight 25s Heat Press. I'm sublimating lycra blend fabric panels, and have two different heat presses to work with. The 25s is shrinking the fabric excessively, and causing the color to come out very saturated and darker than when pressed on the other machine. We've tried pressing anywhere from 300 to 400 degrees Fahrenheit, at anywhere from 25 seconds to 1 minute. Any help would be much appreciated, as i am up against a deadline and cant find the answer anywhere. Please Help!!
