An ink-jet apparatus and method, and a gas supply unit are provided to reduce damage to the ink-jet apparatus due to external gas supply by installing the gas supply unit. An ink-jet apparatus includes an ink-jetting unit(2), and a gas supply unit(3). The ink-jetting unit includes a base part(10), a stage(21), and a nozzle head. The stage and the nozzle head are perpendicularly disposed to each other, and connected to a stage drive part and a nozzle head drive part. The gas supply unit supplies a gas into the ink-jetting unit. The gas supply unit includes an auxiliary gas supply part(51), gas pipes(61-64), a gas supply source selection part(71), and a pressure regulation part(72). The base part has a substantially rectangular shape, and extends in a stage moving direction. The base part is supported by four posts(11). The stage reciprocates along a rail part(13). |
