  • Patent number: 8267505
    Abstract: There is disclosed an ink set and method for printing an inkjet ink image on a nonporous substrate. The inkset and method comprise one or more inkjet inks comprising at least one first pigment-based inkjet ink having a first colorant load of a pigment and a polymeric latex binder; and at least one second pigment-based inkjet ink having a second colorant load of the pigment and a polymeric latex binder, the second colorant load being less than the first colorant load, and the second pigment-based inkjet ink applied to a substrate in an amount to provide a total ink loading of from about 10 g/m2 to about 30 g/m2.
    Type: Grant

  • Patent number: 6752491
    Abstract: An ink jet printer having an ink delivery system that allows air to be absorbed by ink that is being delivered to an ink jet print cartridge that includes a thermal printhead, so that ink delivered to the printhead has an air saturation level of at least 30%. The dissolved air reduces damage to heater resistors of the thermal ink jet printhead that would otherwise be caused by the in rush of ink after an ink drop is fired.

  • Patent number: 6350018
    Abstract: An ink jet printhead that includes a thin film substructure having heater resistors formed therein, an ink barrier layer disposed one the thin film substructure, a plurality of ink chambers formed in said ink barrier, a plurality of ink channels respectively fluidically connected to the ink chambers and opening towards an ink feed edge, a plurality of elongated angled barrier islands extending from the feed edge into respective ink channels, and a plurality of non-elongated barrier islands alternatingly located with the non-linear elongated barrier island along the ink feed edge.
