What is dye-sublimation? Dye-sublimation is a technique of transferring colors using heat. Why is that important for the flag you’re about to purchase? Easy; the use of dye-sublimation produces brilliant, bright, long-lasting colors!
Those brilliant, bright, long-lasting colors are possible because of the process, itself. To begin, a special sublimation ink is applied to a donor material (like paper) in a liquid state that is then allowed to dry. Then the donor material is introduced to the fabric and heat is applied— enough heat to turn the ink into a gas that permeates the material completely. The heat is then removed and the ink dries.
Originally, dye-sublimation was for printing on paper products, but was modified when testing on fabric proved beneficial for the color brightness and longevity. It also produces a color that is evenly distributed through the material as a result of the gaseous state of the ink during the heating process.
Regular fabric printing is applied to one side of the material and is allowed to bleed through giving the reverse side its color. You can usually tell when a flag is surface printed by comparing the colors on the two sides.
So if you want a flag with vibrant, out-standing colors, look for dye-sublimation in the description. It’s that important.
