    Abstract: A white ink can include an aqueous ink vehicle, from 5 wt % to 25 wt % of white metal oxide pigment having an alumina coating, a dispersant associated with a surface of the white metal oxide pigment, and from 0.05 wt % to 0.5 wt % of amphoteric alumina particles having an average particles size from 2 nm to less than less than 100 nm. The white ink can further include from 0.3 wt % to 1.1 wt % monovalent metal salt, or from 0.005 wt % to 0.175 wt % divalent metal salt, or both.

    Abstract: According to an example, a method for TIJ printing may include applying, by a processor, F electrical firing pulses to a resistor of a TIJ printhead for a duration of about 0.50 to 1.00 μs to jet a latex ink or a dispersed polymer particle ink from a nozzle. According to another example, a TIJ printing apparatus may include a TIJ printhead including a firing chamber to jet a latex ink or a dispersed polymer particle ink from a nozzle, and a resistor to heat the latex ink or the dispersed polymer particle ink to jet from the nozzle. The TIJ printing apparatus may further include a memory storing machine readable instructions to apply F electrical firing pulses to the resistor for a duration of about 0.50 to 1.00 μs to jet the latex ink or the dispersed polymer particle ink, and a processor to implement the machine readable instructions.

    Abstract translation: 根据一个实例，用于TIJ打印的方法可以包括由处理器将F电触发脉冲施加到TIJ打印头的电阻器，持续时间为约0.50至1.00μs，以将胶乳油墨或分散的聚合物颗粒墨水从 一个喷嘴。 根据另一示例，TIJ打印设备可以包括TIJ打印头，其包括用于从喷嘴喷射胶乳油墨或分散的聚合物颗粒油墨的燃烧室，以及用于加热胶乳油墨或分散的聚合物颗粒油墨以从 喷嘴。 TIJ打印设备可以进一步包括存储机器可读指令的存储器，以将F电触发脉冲施加到电阻器约0.50至1.00μs的持续时间以喷射胶乳油墨或分散的聚合物颗粒油墨，以及处理器来实施机器 可读指令。

    Abstract: The present disclosure provides a white ink including an aqueous ink vehicle, from 5 wt % to 50 wt % of a white metal oxide pigment having an average particulate size from 100 nm to 2,000 nm, from 0.02 wt % to 2 wt % of an anionic low molecular weight polymer having a weight average molecular weight of 3,000 Mw to 50,000 Mw and an acid number higher than 100 mg KOH/g based on dry polymer weight, and from 2 wt % to 30 wt % of latex particulates having a glass transition temperature from 0 C to 130 C. Furthermore, the white metal oxide pigment is dispersed by a non-ionic or predominantly non-ionic dispersant having an acid number not higher than 100 mg KOH/g based on dry polymer weight.

    Abstract: The present disclosure provides a white ink including an aqueous ink vehicle, from 5 wt % to 50 wt % of a white metal oxide pigment having an average particulate size from 100 nm to 2,000 nm, from 0.1 wt % to 4 wt % of anionic oxide particulates having an average particulate size from 1 nm to 100 nm, from 2 wt % to 30 wt % of latex particulates having a glass transition temperature from 0 C to 130 C, and a non-ionic or predominantly non-ionic dispersant having an acid number not higher than 100 mg KOH/g based on dry polymer weight. The white metal oxide pigment and anionic oxide particulates are present in the white ink at a weight ratio from 5:1 to 200:1.
