Patent number: 10844236Abstract: 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.Type: GrantFiled: July 20, 2016Date of Patent: November 24, 2020Assignee: Hewlett-Packard Development Company, L.P.Inventors: Max Yen, Yi-Hua Tsao, Marisa Weaver, Elizabeth Ann Visnyak, Jessica Rikki Vosler, Jon A.

Patent number: 9546293Abstract: 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.Type: GrantFiled: September 25, 2012Date of Patent: January 17, 2017Assignee: Hewlett-Packard Development Company, L.P.Inventors: George Sarkisian, Ali Emamjomeh, Elizabeth Ann Visnyak
