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, said liquid ink formulation comprising heat activated dye solids, at least one emulsifying enforcing agent for shielding the heat activated dye solids and at least one solvent, wherein said emulsifying enforcing agent emulsifies said heat activated dye solids within the liquid ink formulation; 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 and permanently bond said image to said substrate, wherein said image is resistant to laundering.
