Abstract: An inkjet receptive composition for use on glossy paper substrates may include a polymer binder, a multivalent salt, a pigment, a surfactant, a defoamer, and water. The polymer may be a polyurethane dispersion. The multivalent salt may be calcium chloride, and the water may be present in an amount greater than about 40 wt %. The inkjet receptive composition may have a viscosity in the range of about 3 and about 500 cP.

Abstract: According to one aspect, an ink composition includes a colorant, a polyurethane having a peak average molecular weight range of from about 25,000 g/mol to about 35,000 g/mol, and a solvent. The ink composition has a total solids content of less than about 12% by weight, and a ratio of colorant to polyurethane between about 1:1 and 1:2 by weight.

Abstract: An apparatus for controlling application of a substance to a substrate involves the use of a gating agent that blocks the substance from or attracts the substance to the substrate. The apparatus may utilize ink jet technology to apply the gating agent directly to the substrate or to an intermediate surface. The gating agent includes a nonionic surfactant, and water. The gating agent does not contain a discernable amount of dye, pigment or other colorant agent.

Abstract: Apparatus and methods for controlling application of a substance to a substrate involve the use of a functional agent that blocks the substance from or attracts the principal substance to the substrate. The apparatus and methods may utilize ink jet technology to apply the functional agent directly to the substrate or to an intermediate surface. The principal substance may be an ink, a dye, a marking substance other than an ink, or a carrier for any other type of substance.

Abstract: A cleaning system for an inkjet printhead comprises an inkjet printhead having an inkjet nozzle array associated therewith. The inkjet printhead is in fluid communication with a first source of a first pressurized fluid. A fluid nozzle associated with the inkjet printhead is in fluid communication with a second source of a second pressurized fluid. The cleaning system further comprises a collection plate. Ink is forcibly ejected from the inkjet printhead by the first source of the first pressurized fluid. A stream of the second pressurized fluid is guided by the fluid nozzle across a surface of the inkjet printhead to direct ink ejected from the inkjet printhead onto the collection plate.
