A type of sublimable dye that requires a very high temperature (over 400ºF) in order to be transferred to the substrate. Since these dyes undergo sublimation at very high temperatures, they are less susceptible to washing out of the fabric on which they are printed. However, some high-energy dyes are only transferred at temperatures which would cause damage to fabric, and are used in other types of applications. See also Low-Energy Dye.
