Dye sublimation is the printing process which produces washable all-over prints on the softest of polyester fabrics. The process is distinctive in that it creates designs by using disperse dyes inks in their gaseous form. Designs are first printed onto transfer paper the width and height of the t-shirt being printed. Then using a heat press, the transfer paper is placed on top of the apparel being printed and pressed down. The heat and pressure allow the dried inks on the transfer paper to turn into a gas and penetrate the polyester fabric of the apparel leaving a permanent soft-hand feel to the design of your all over print shirt.
