摘要

In the inkjet printing method: a step of printing a first ink on a print medium, wherein the first ink includes a first self-dispersing pigment, and the first ink has a first pigment content A. And subsequently printing a second ink at least partially on a print medium on the first ink, wherein the second ink encapsulates the second pigment and the second pigment. Including a polymer dispersant, wherein the second ink has a second pigment content B. The first self-dispersing pigment and the second pigment have the same color; the pigment content A of the first ink and the pigment content B of the overprinted second ink are 0.8 ≦ A / B ≦ 1.2; the polymer acidity index of the polymeric dispersant is in the range of 100 to 170.
