Abstract
An image is printed on a medium by means of an ink jet printer using an ink composition comprising heat activated ink solids, without activating the ink solids during the process of printing onto the medium. The image is transferred from the medium to the object on which the image is to permanently appear by applying sufficient heat and pressure to the medium to activate and transfer the ink to the object.
Claims6
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.
