Abstract
In an ink jet printing method for discharging ink from a liquid discharge head, the ink contains titanium oxide having a precipitation velocity of 1.0×10−11 m/s or more based on a Stokes equation in the ink, the liquid discharge head comprises a discharge port, a pressure chamber, an energy-generating element, an upstream flow channel for supplying a liquid to the pressure chamber, a downstream flow channel communicating with the pressure chamber, and a pump communicating with the upstream flow channel and the downstream flow channel and forming a circulation path in which the ink circulates in an order of the upstream flow channel, pressure chamber, downstream flow channel, and upstream flow channel, the liquid discharge head is configured so as to perform reciprocal scan, and a scanning velocity in a region where the liquid discharge head scans at a constant velocity is higher than the precipitation velocity.
