Abstract: A thermal inkjet ink set includes a pre-treatment fixing fluid, an ink, and a post-treatment fluid. The pre-treatment fixing fluid includes a metal salt. The ink includes an ink vehicle and a colorant. The post-treatment fluid includes a fluid vehicle and an anionic polyurethane acrylic hybrid polymer binder dispersed in the fluid vehicle. The anionic polyurethane acrylic hybrid polymer binder is present in an amount ranging from greater than 0 wt % to about 25 wt %. The anionic polyurethane acrylic hybrid polymer binder includes an acrylic polymer or copolymer, and an anionic polyurethane polymer encapsulating the acrylic polymer or copolymer.

Abstract: An example of a liquid bonding agent, for a liquid ink including a wax emulsion in an amount less than 1% actives, includes a calcium salt, the wax emulsion, an acetylenic surfactant, a glycol, and a balance of water. The wax emulsion is present in the liquid bonding agent in an amount ranging from greater than 0% actives to about 2% actives. The liquid bonding agent is to be digitally printed with a thermal inkjet printhead on a substrate under the liquid ink.

Abstract: An inkjet printing system is described herein. In an implementation, the inkjet printing system includes a fixer dispensing unit for applying a fixer composition on a substrate and an ink dispensing unit for applying an ink composition on the substrate. The fixer composition includes a metal salt in a range of about 5% to 10% by weight. Further, the ink composition includes a liquid vehicle having a non-volatile organic solvent, a colorant dispersed in the liquid vehicle, and a latex binder dispersed in the liquid vehicle.

Abstract: The present disclosure sets forth a fluid set and a method of wet-on-wet printing. The fluid set can comprise an analog pretreatment fluid including water, latex, and a salt; and a first and second inkjet ink each comprising water, pigment, a solvent system, and a surfactant system. The analog pretreatment fluid can be prepared to have a surface tension from 32 dynes/cm to 40 dynes/cm. The first inkjet ink can have a surface tension ranging from 2 dynes/cm greater than the surface tension of the analog fixer fluid to 6 dynes/cm less than the surface tension of the analog fixer fluid. Likewise, the second inkjet ink can have a surface tension ranging from 2 dynes/cm greater than the surface tension of the analog fixer fluid to 6 dynes/cm less than the surface tension of the analog fixer fluid.
