Abstract: Provided are a holographic printer and a holographic printing method. The holographic printer according to an embodiment of the present invention comprises: an optical modulation unit for displaying a holographic fringe pattern for a certain portion of an object and diffracting an incident wave; and a filtering unit for shielding a component in the diffracted wave field outputted from the optical modulation unit to be transmitted to a certain area of a holographic recording medium. The holographic printer can partially record the holographic fringe pattern in the holographic recording medium in a hogel unit so that the more realistic hologram can be recorded. Furthermore, the holographic printer filters the diffracted wave field outputted from the holographic fringe pattern to record the holographic fringe pattern while removing the unconformable components, thereby eliminating a tiling phenomenon of the hologram.
