INK JET PRINTING METHOD

This abstract first appeared for US patent application 20240408886 titled 'INK JET PRINTING METHOD

Original Abstract Submitted

in an ink jet printing method for printing an image on a print medium by discharging an aqueous ink and an aqueous reaction liquid containing a reactant that reacts with the aqueous ink from a liquid discharge head, the liquid discharge head includes an element substrate, upstream and downstream flow channels, a pump, and a temperature control unit. the element substrate includes a discharge port discharging the aqueous reaction liquid, a pressure chamber supplying a liquid to the discharge port, and a discharge element generating energy for discharging the liquid. the upstream flow channel supplies a liquid to the pressure chamber. the downstream flow channel communicates with the pressure chamber. the pump communicates with the upstream and downstream flow channels and allows a liquid in the downstream flow channel to flow in the upstream flow channel. the temperature control unit heats the aqueous ink or the aqueous reaction liquid.
