Hi, I have used the specially treated and my own prepared fabrics (I just iron it onto freezer paper), and set the saturation level on the ink up about 25 percent. Then I let it dry for 15 minutes, remove the backing, if any, and heat set it with my iron. After that, I rinse it in water, drip dry it and iron it again. I have not had it fade and the colors are usually great. Hope this helps.
