Abstract
A nonaqueous inkjet printing method that can provide prints with both high printing density and good gradation is provided. The nonaqueous inkjet printing method comprises printing an image by an inkjet recording system using a first nonaqueous ink comprising at least a coloring pigment, a water-soluble resin having an amino group, and a nonaqueous solvent, and then printing an image so as to overlap with the preceding image by an inkjet recording system using a second nonaqueous ink, wherein the second nonaqueous ink comprises at least a coloring pigment, inorganic particles, and a nonaqueous solvent, and the content of the coloring pigment in the second nonaqueous ink is lower than the content of the coloring pigment in the first nonaqueous ink. The first nonaqueous ink is preferably printed at a higher resolution of printing than the second nonaqueous ink.
