Patent ID: 6957886

Claim:
An inkjet printing system comprising: a printhead comprising an ink cartridge having a housing, portions of the housing defining an ink chamber having a nozzle bore, the housing being operable to heat an ink comprising a binder located in the ink chamber to a temperature exceeding 50° C., the ink being optimized for ejection through the nozzle bore in the form of an ink drop after the ink is heated to the temperature exceeding 50° C.; and a platen positioned relative to the printhead, portions of the platen defining a path to convey media by the printhead, the platen including a first heater located upstream from the printhead, the first heater being operable to heat the media to a first temperature prior to the media reaching the printhead, the platen including a second heater positioned downstream from the printhead, the second heater being operable to heat the media to a second temperature after the media passes the printhead, the second temperature being greater than the first temperature, wherein the binder is present in the ink in a concentration sufficient to give the ink a viscosity of at least 3.50 cps as measured at a temperature of 25° C. and a viscosity of less than 2.65 cps as measured at a temperature of 65° C.
