Abstract: An ink jet printing composition comprises from 1.00% to 6.00% by weight of at least one pigment, from 5.00% to 11.00% by weight of at least one polymer, from 14.50% to 17.50% by weight of at least one co-solvent, from 4.50% to 5.50% by weight of at least one humectant, from 1.00% to 2.75% by weight of at least one surfactant, and water. Other ink jet printing compositions and a method of printing are also disclosed.

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: 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.
