The invention relates to a method for preparing titanium dioxide special for ink. The method is characterized by comprising the following steps: firstly, treating industrial titanium dioxide by using inorganic matters so as to obtain inorganic matter wrapped titanium dioxide; and secondly, treating the industrial titanium dioxide with water-soluble organic matters, thereby obtaining titanium dioxide which is wrapped by both inorganic matters and organic matters. The titanium dioxide prepared by using the method is relatively good in weather resistance and dispersibility in ink systems, can be used as a white pigment in ink, particularly aqueous ink, and can be kept dispersed when the ink is stored and used, and thus precipitation and ink ejection hole blocking are avoided.
