In an ink-jet printing process droplets of two or more inks are ejected so that the inks are applied adjacent to each other or at least superpose each other on a recording medium. The inks are different in color from each other, the respective inks containing a nonionic surfactant of 1.0 to 20.0% by weight based on the total weight of the ink, and respective ink droplets having a volume of from 10 to 70 pl. The feathering rate (A) defined by equation [I] is in the range of from 2.5 to 3.5: A=B/C [I] where B is a diameter (µm) of a dot formed on plain paper, and C is a diameter (µm) of the ejected ink droplet.
