Abstract
An apparatus and method of thermal inkjet printing is provided. The apparatus is adapted to be used with an inkjet ink including a pigment(s), an aqueous vehicle, and a sufficient amount of polymeric binder and/or humectant(s) to wet and directly adhere to non-porous, uncoated, untreated, hydrophobic media. The ink is adapted to be ejected through a thermal inkjet head with consistent image quality and no kogation. The concentration of binder and/or humectant(s) raises the viscosity of the ink at room temperature. As such, the apparatus is adapted to lower the viscosity of the ink prior to the ink being ejected through the thermal inkjet printhead. Additionally, the apparatus is adapted to prepare the media for receiving the ink, and dry the ink after the ink is deposited on the media. This can be accomplished by providing heat to the media and/or the ink during the printing process.
