The present invention provides an ink-jet printing method using a water-based ink for ink-jet printing which is excellent in quick-drying fixing properties and long-term fixing properties when printing characters or images on a low-water absorbing recording medium, as well as ejection stability. The present invention relates to [1] an ink-jet printing method of printing characters or images on a recording medium using a water-based ink for ink-jet printing, in which the recording medium has a water absorption of not more than 10 g/m2 and not less than 0 g/m2 as measured in a pure water contact time of 100 milliseconds; the water-based ink includes a pigment (A), resin particles (B), a polypropylene glycol (X) and water; and the resin particles (B) are produced by emulsion polymerization method; and [2] the aforementioned water-based ink for ink-jet printing.
