Abstract
The present invention is a method of producing a printed a by printing heat activated ink solids in a non activated form onto a medium in a desired image by means of an ink jet printer. The invention is printed using ink or dye compositions comprising heat activated ink or dye solids. The ink compositions used to print the medium are solid at ambient temperature when used with phase change ink jet printers, and are emulsions when used with liquid ink jet printers such as free flow and bubble jet printers. The dye solids are printed in the desired design by means of a printer onto a substrate, which becomes the printed medium. The substrate may be paper, or it may be other material.
Claims14
A printed medium produced by a process comprising the steps of:
- a. preparing a solid ink jet ink formulation comprising heat activated dye solids, from 1% to 20% of at least one emulsifying enforcing agent, and from 20% to 70% by weight of a transfer vehicle;
- and from 0% to 30% by weight of a binder;
- b. supplying an ink jet printer with said ink formulation:
- c. printing said ink formulation in a desired image by means of said jet printer onto a medium at a temperature which is below the temperature at which said heat activated dye solids activate, wherein said solid ink jet formulation is liquefied by said ink jet printer, and wherein said at least one emulsifying enforcing agent emulsifies said heat activated dye solids within said ink jet formulation during liquefaction of said solid ink jet formulation by said ink jet printer.
A printed medium produced by a process 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 least one emulsifying enforcing agent for shielding the heat activated dye solids and at least one liquid carrier wherein said ink formulation comprises not less than 1%, nor more than 20%, of said at least one emulsifying enforcing agent by weight;
- b. supplying an ink jet printer which uses liquid ink with said liquid ink formulation;
- and
- c. printing said liquid ink formulation in a desired image by means of said ink jet printer onto a substrate at a temperature which is below the temperature at which said heat activated dye solids activate.
A printed medium produced by a process 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 water;
- b. supplying an ink jet printer which uses liquid ink with said liquid ink formulation;
- and
- c. printing said liquid ink formulation in a desired image by means of said ink jet printer onto a substrate at a temperature which is below the temperature at which said heat activated dye solids activate.
A printed medium produced by a process 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 liquid carrier, 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 liquid carrier by means of said emulsifying enforcing agent, wherein said ink formulation comprises not less than 1%, nor more than 20%, of said at least one emulsifying enforcing agent by weight;
- 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 substrate at a temperature which is below the temperature at which said heat activated dye solids activate.
A printed medium produced by a process comprising the steps of:
