The present invention provides a flexographic plate water-based ink for high-speed printing and a preparation method thereof. The flexographic plate water-based ink comprises the following components by weight: 30-40 parts of a non-film forming acrylic emulsion, 5-10 parts of an acrylic film-forming emulsion, 15-0 parts of an acrylic resin solution, 30-40 parts of an aqueous paste, 1-3 parts of polyethylene wax, 1-2 parts of a film-forming aid, 0.3-1 part of a leveling agent, 0.1-0.5 part of a defoamer, 3-7 parts of deionized water and a pH modifier. The non-film forming acrylic emulsion is an acrylic emulsion with Tg value no less than 90 DEG C, the acrylic film-forming emulsion is an acrylic emulsion with Tg value less than 30 DEG C, the content of the pigment in the aqueous paste is 40-45%, and the pH modifier reaches pH value of the flexographic plate water-based ink of 8-9.5. The water-based ink can well adapt to printing of high-speed satellite-type press, and has good re-solubility and excellent leveling and trapping effect; and the printed product has high color saturation, bright color and good gloss; therefore, the water-based ink has wide range of applications.
