摘要： An ink jet printing apparatus includes a table which places a print medium on, a switching unit which switches the print medium to a fixed state or a released state with respect to the table, a carrying unit which carries the table, at least one or more print heads which eject ultraviolet curable ink, a first UV curing unit which is provided downstream from each of the print heads along a direction of carrying the table from an initial position toward the print heads and casts ultraviolet rays to provisionally cure the ultraviolet curable ink, and a second UV curing unit which is provided downstream from the first UV curing unit provided on the most downstream side along the direction of carrying the table from the initial position toward the print heads and casts ultraviolet rays to fully cure the ultraviolet curable ink.

摘要： A circulating type ink supply system includes an upstream ink tank, an upstream ink flow channel connected at one end thereof to the upstream ink tank, a nozzle branch portion connected to the other end of the upstream ink flow channel and being in communication with a nozzle configured to discharge ink, a downstream ink flow channel connected at one end thereof to the nozzle branch portion and a downstream ink tank connected to the other end of the downstream ink flow channel, wherein an energy per unit volume determined by a sum value of a static pressure and a potential energy of the ink in the upstream ink tank when the circulation of the ink is stopped does not exceed the energy per unit volume of the ink at an atmospheric pressure at a level of the nozzle.
