Abstract: A method of internal recirculation printing can include introducing an ink composition into a firing chamber, the ink composition comprising water, organic co-solvent, pigment, and from 2 wt % to 20 wt % of a dispersed polymer binder with an acid number from 0 mg KOH/g to 45 mg KOH/g, a weight average molecular weight of 40,000 Mw to 2,000,000 Mw, and a particle size from 40 nm to 2 μm. The method can further include internally recirculating ink composition from the firing chamber, through micro-recirculation fluidics, and back into the firing chamber to be again recirculated or ejected from the firing chamber, as well as ejecting ink composition from the firing chamber through a jetting nozzle onto a substrate.
