Abstract: An example of a dye sublimation inkjet ink includes a disperse dye colorant dispersion; a water soluble polymeric ultraviolet (UV) absorber; a co-solvent; and a balance of water. The water soluble polymeric UV absorber of the dye sublimation inkjet ink has absorption at a radiation wavelength ranging from about 360 nm to about 410 nm.

Abstract: In an example of a textile printing method, a thermally curable ink composition is applied on a fabric substrate. The thermally curable ink composition includes from about 1 wt % active to about 6 wt % active of a pigment that absorbs ultraviolet radiation, infrared radiation, or a combination thereof, based on a total weight of the thermally curable ink composition; from about 2 wt % active to about 20 wt % active of a polymeric binder, based on the total weight of the thermally curable ink composition; and an aqueous ink vehicle. In the method, the pigment of the thermally curable ink composition is selectively heated on the fabric substrate by exposing the fabric substrate to an emission wavelength from a narrow wavelength light source for a total exposure time of 3 seconds or less. The selective heating thermally fixes the pigment to the fabric substrate.

Abstract: A fluid set can include an ink composition having a pH from pH 7 to pH 10 and a crosslinker composition having a basic pH from pH 8 to pH 10. The ink composition can include from 60 wt % to 90 wt % water, from 5 wt % to 30 wt % organic co-solvent, from 1 wt % to 6 wt % pigment, and a latex polymer including an aromatic (meth)acrylate moiety. The crosslinker composition can include from 70 wt % to 95 wt % water, from 1 wt % to 25 wt % organic co-solvent, and from 1 wt % to 10 wt % polycarbodiimide.

Abstract: Examples described herein include printing systems that include a transfer medium, a binder material applicator to apply a layer of binder material to a surface of the transfer medium, and a print engine to apply printing material to the layer of binder material. The system can also include a roller to press the transfer medium against a print medium to transfer the binder material and the printing material to the print medium.

Abstract: A printhead of a printer includes a nozzle plate having a first layer, a second layer, and an intermediate channel. The first layer can have at least one fluid chamber for holding an immiscible fluid, and a plurality of ejection fluid chamber for holding an ejection fluid. The second layer can have a plurality of ejection fluid nozzles, one ejection fluid nozzle being in fluid communication with one ejection fluid chamber. The intermediate channel can form a passage between the first layer and the second layer. Further, the intermediate channel is in fluid communication with the fluid chambers to carry the immiscible fluid from the fluid chambers towards each of the ejection fluid nozzles for forming a layer of the immiscible fluid over the ejection fluid chambers to maintain the printhead.
