ABSTRACT:
A thermal ink jet printing comprises incorporating into a thermal ink jet printer at least one ink jet ink with an ink composition comprising water; a colorant of a dye or pigment; a hydroxyamide derivative having at least one hydroxyl group and at least one amide group or a reaction product of oxyalkylene(s) and the said hydroxyamide derivative; a sulfur-containing humectant that is a sulfoxide or a sulfone or a thiol derivative. Printing with the ink jet ink is according to digital signals with at least one printhead which is selected from a group consisting of single, partial-width, and full-width array printheads using a checkerboard or single pass method onto a print substrate either with or without the presence of heat for drying. The ink jet ink has a good latency, long-term jetting stability, and good image quality on plain papers when it is used in a high resolution thermal ink jet printhead including a 600 spi printhead.
