1. A method of printing a design by means of an ink jet printer using heat activated dye solids, comprising the steps of:

  • a. preparing an 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;

    b. supplying an ink jet printer with said ink formulation;

    c. printing said 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.
