Abstract
A liquid ink is produced for practicing a method of printing the liquid ink onto a medium for subsequent thermal transfer to a substrate. Insoluble heat activated dyes, such as sublimation or dye diffusion dyes, are heated to above their melting temperature to the same phase as the solvent, which is usually water. Additives and/or stabilizers are added to form micelle particles upon cooling of the material, without separation of the insoluble components, to produce the liquid ink.
