  • PRINTING FLUID CIRCULATION
    Publication number: 20230202184
    Abstract: An example printing fluid pen comprises a plurality of fluid ports, including an inlet port to direct fluid from a fluid reservoir to a fluid ejection device, and a recirculation port to direct fluid from the fluid ejection device out of the inkjet pen. The example pen also includes a plurality of parallel fluid pressure regulators fluidly coupled with the inlet port, each of the plurality of parallel fluid pressure regulators to receive fluid from the inlet fluid port.

  • Liquid bonding agent for liquid ink
    Patent number: 10844236
    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.

  • SUBSTRATE COATING
    Publication number: 20180229524
    Abstract: In an example implementation, a substrate coating system includes a resist printing device to print resist fluid onto a selected area of a substrate surface. The system includes an analog coating device to apply coating fluid onto the entire substrate surface, wherein the resist fluid resists application of the coating fluid on the selected area of the substrate surface.

  • Fluid flux correction
    Patent number: 9221266
    Abstract: Fluid flux correction is disclosed. An example method of fluid flux correction includes displacing a fluid volume in a fluid reservoir with a compliant element. The method also includes absorbing fluid surges caused by variations in fluid flux to reduce distortion of at least one ink nozzle meniscus and maintain consistent fluid ejection.
