Abstract:
A method of printing a design by means of an ink jet printer using heat activated dye solids, comprising the steps of:a. preparing a liquid ink formulation suitable for use in an ink jet printer which uses liquid ink, wherein said liquid ink formulation comprises at least one solvent, at least one emulsifying enforcing agent, and heat activated dye solids which are finely divided to a particle size which yields an emulsion when said heat activated dye solids are emulsified within said at least one solvent by means of said emulsifying enforcing agent; b. supplying an ink jet printer which uses liquid ink with said liquid ink formulation; c. printing said liquid ink formulation in a desired image by means of said ink jet printer onto a medium at a temperature which is below the temperature at which said heat activated dye solids activate; and d. transferring said image from said medium to an object on which the image is to appear by thermal means at a temperature which is above the temperature at which said heat activated dye solids activate, so as to cause said heat activated dye solids to transfer onto said object.
