Abstract

A method of inkjet printing includes the steps of: printing a first ink onto a print medium, the first ink including a first self-dispersible pigment, the first ink having a first pigment content A; and subsequently printing a second ink onto the print medium at least partially over the first ink, the second ink including a second pigment and a polymeric dispersant encapsulating the second pigment, the second ink having a second pigment content B. The first self-dispersible pigment and the second pigment have a same color; the pigment content A of the first ink and the pigment content B of the overprinted second ink have a relationship 0.8≦A/B≦1.2; and a polymer acid value of the polymeric dispersant is in the range of 100 to 170.
