An ink contains an anionic compound, water, a photoacid generator, and one or more organic solvents containing at least one organic solvent having a solubility parameter of from 9 to 11.8 (J/cm.sup.3).sup.1/2.

The present disclosure describes fluid sets for printing, methods of textile printing, and textile printing systems. In one example, a fluid set for printing can include a pretreat composition, a fixer composition, and a white ink composition. The pretreat composition can include water and an emulsion of a silicone polymer having amino groups. The fixer composition can include a liquid vehicle and a cationic polymer. The white ink composition can include a liquid vehicle, a white pigment dispersion, and a polymeric binder.
