Zusammenfassung:	The present invention relates to an aqueous ink for plate-based printing, which contains the following components (A) to (C) and water: (A) not less than 1% by mass and not more than 15% by mass of a pigment; (B) not less than 1% by mass and not more than 12% by mass of pigment-free crosslinked polymer particles; and (C) not less than 1% by mass and not more than 15% by mass of a water-soluble organic solvent having a boiling point of not lower than 100° C. and not higher than 260°, and a plate-based printing method including the step of printing characters or images on a low-liquid absorbing printing medium using the aforementioned aqueous ink. The aqueous ink for plate-based printing according to the present invention hardly suffers from occurrence of tone jump and is excellent in anti-blocking properties even when printed on a low-liquid absorbing printing medium.
