Abstract
The present disclosure is drawn to an inkjet printing system including an ink composition and a microfluidic ejection assembly. The ink composition can include carbon black pigment, from 50 wt % to 80 wt % water, from 10 wt % to 40 wt % of an organic solvent system, and from 0.5 wt % to 6 wt % polyurethane. The microfluidic ejection assembly can include a drop generator for externally ejecting the ink composition, and a fluid pump for internally inducing microfluidic recirculation flow of the ink composition into the drop generator.
