A method of inkjet printing includes ink jetting an aqueous inkjet ink composition to form a white printed image on a substrate. The aqueous inkjet ink composition comprises particles of titanium dioxide that are present in an amount of at least 4 to 15 weight % and the particles have a 95th percentile particle size of less than 200 nm and a 50th percentile particle size of less than 130 nm. The titanium dioxide particles are dispersed within the aqueous inkjet ink composition using a dispersing polymer that is a styrene-(meth)acrylic acid polymer, styrene-maleic anhydride polymer, or styrene-maleic acid polymer and the weight ratio of the titanium dioxide particles to the dispersing polymer is from 19:1 to and including 2:1.
