Abstract
An object is to provide a method for storing or transporting an aqueous white ink composition for inkjet that does not cause precipitation of a pigment therein during storage for a long period or transport, and allows the pigment to be easily redispersed even if precipitation occurs. As means for solving the problems, a storing method is provided that includes placing an aqueous white ink composition for inkjet containing titanium oxide and a pigment dispersant in a tank and maintaining the entire aqueous white ink composition for inkjet in the tank at a temperature of −5 to −35° C.
