摘要： The invention relates to an aqueous magenta inkjet ink composition for use in ink jet printers comprising a mixture of a self-dispersed magenta pigment surface modified with functional group and a xanthene dye. The magenta ink of the present invention also contains an aqueous carrier, a polymeric additive, a surfactant, and a specific cosolvent mixture selected from the group consisting of a C2-C8 terminal alkanediol, cyclic amide compound and its derivative, trihydric alcohol and mixtures thereof. Preferably, the magenta pigment is surface modified with bisphosphonate or sulfonate group, most preferably bisphosphonate group. The magenta inkjet ink demonstrates excellent stability, good chroma and maintenance characteristics and high heater reliability in permanent and semi permanent printheads. The ink also reduced post print paper curl without sacrificing print quality.

摘要： The invention provides a printing apparatus for printing an image having a spatial resolution onto a print medium. The printing apparatus includes a printhead having a plurality of printing elements for ejecting ink droplets having a mass onto the print medium, and a temperature sensor for sensing a temperature of the printhead, producing a temperature signal. The apparatus also includes a media sensor for determining what type of print medium is loaded in the printer and producing a print medium signal based on the type of print medium installed in the printer. A plurality of heating devices are located adjacent the printhead for adjusting the temperature the printhead. The apparatus includes a printer controller for receiving the temperature signal from the temperature sensor and the print medium signal from the media sensor, and determines the ink temperature based on the print medium signal, and activates the heating devices to maintain the temperature of the printhead within a desired temperature range that is dependent upon the print medium signal.
