A method of forming a mark, the method comprising:
- heating an edible hot melt ink to a temperature sufficient to liquefy the ink;
- and
- ejecting droplets of the melted ink from a pumping chamber of a drop-on-demand piezoelectric inkjet printhead to form a mark upon the surface of a substrate, the mark having a resolution of at least 50 dpi;
- wherein the ink is completely edible and comprises an edible wax and is free of succinic acid and its derivatives;
- and
- wherein the ink has a melting temperature of between 40° C. and 100° C.
A method of forming a mark, the method comprising:
- heating an edible hot melt ink to a temperature sufficient to liquefy the ink;
- and
- ejecting droplets of the melted ink from a pumping chamber of a drop-on-demand piezoelectric inkjet printhead to form a mark upon the surface of a substrate, the mark having a resolution of at least 50 dpi;
- wherein the ink is completely edible and comprises an edible wax and an edible colorant, the edible hot melt ink being free of succinic acid and its derivatives;
- and
- wherein the ink has a melting temperature of between 40° C. and 100° C.
