A flexographic printer, comprising:
- a printing plate which transfers ink at an ink transfer site to an object to be printed;
- an anilox roll which supplies ink to the printing plate at an ink supply site;
- a plate cylinder around which the printing plate is wound and rotated;
- an ink solvent supply unit which supplies a solvent for ink to the surface of the printing plate in a post-ink transfer region which is a downstream of the ink transfer site in a rotation direction of the plate cylinder and an upstream of the ink supply site in the rotation direction of the plate cylinder;
- and
- a guide which covers the post-ink transfer region from the outside of the plate cylinder and guides the solvent for ink supplied by the ink solvent supply unit to the surface of the printing plate without covering a pre-ink transfer region which is downstream of the ink supply site in the rotation direction of the plate cylinder and upstream of the ink transfer site in the rotation direction of the plate cylinder.
