An ink-jet printing apparatus comprising: an ink-jet head for discharging ink onto a mesh-like medium having through holes penetrating from the top surface (printing surface) to the bottom surface, the ink-jet head having a printing position; a feeder for feeding the mesh-like medium in a feed direction; and a dryer for drying the mesh-like medium hit by ink discharged from the ink-jet head, wherein the dryer has a blower placed under the mesh-like medium for applying an air flow to the bottom surface of the mesh-like medium with the top surface hit by ink, wherein the blower is provided adjacent to the printing position and configured to send the air flow to the mesh-like medium from below, to give the medium un upward force of the air flow, and to dry the ink hit on the top surface of the medium while preventing the medium from being in contact with the drier, characterized in that the ink-jet printing apparatus further comprises: a platen including an ink receiver and an end edge portion formed on the top end of the wall surface on the downstream side thereof such that the medium is in contact with the end edge portion, the latter being configured to give a predetermined tension to the medium at the printing position in conjunction with a tension given by the blower, which can prevent the slack of the medium and can reduce the contact pressure of the medium onto the end edge portion. an ink-jet head for discharging ink onto a mesh-like medium having through holes penetrating from the top surface (printing surface) to the bottom surface, the ink-jet head having a printing position; a feeder for feeding the mesh-like medium in a feed direction; and a dryer for drying the mesh-like medium hit by ink discharged from the ink-jet head, wherein the dryer has a blower placed under the mesh-like medium for applying an air flow to the bottom surface of the mesh-like medium with the top surface hit by ink, wherein the blower is provided adjacent to the printing position and configured to send the air flow to the mesh-like medium from below, to give the medium un upward force of the air flow, and to dry the ink hit on the top surface of the medium while preventing the medium from being in contact with the drier, characterized in that the ink-jet printing apparatus further comprises: a platen including an ink receiver and an end edge portion formed on the top end of the wall surface on the downstream side thereof such that the medium is in contact with the end edge portion, the latter being configured to give a predetermined tension to the medium at the printing position in conjunction with a tension given by the blower, which can prevent the slack of the medium and can reduce the contact pressure of the medium onto the end edge portion. a platen including an ink receiver and an end edge portion formed on the top end of the wall surface on the downstream side thereof such that the medium is in contact with the end edge portion, the latter being configured to give a predetermined tension to the medium at the printing position in conjunction with a tension given by the blower, which can prevent the slack of the medium and can reduce the contact pressure of the medium onto the end edge portion.
