  • Publication number: 20200224051
    Abstract: An example of an inkjet pre-treatment fluid for dye sublimation printing consists of a humectant; a cationic polymer; a surfactant; a co-solvent present in an amount up to about 50 wt % based on a total weight of the inkjet pre-treatment fluid; and a balance of water. In an example of a printing method, the inkjet pre-treatment fluid is inkjet printed onto a textile substrate to form a pre-treated area on the textile substrate.

  • Publication number: 20180281468
    Abstract: An example printing device composing a first printhead and a second printhead is described. In some examples the example printing device comprises a controller. The example printing device is to operate in a first operating mode in which the first printhead is to dispense a first printing substance, the first printing substance to transfer color via a first colorant transfer mechanism, and to operate in a second operating mode in which the second printhead is to dispense a second printing substance, the second printing substance to transfer via a second colorant transfer mechanism different to the first colorant transfer mechanism. An example controller is to cause the example printing device to operate in a selected one of the first and second operating modes.
