An ink jet printing method uses an ink jet printing apparatus 1 including a head 5, and a printing platen 2 for heating a medium 100 from a back side of a surface of the medium 100, wherein the ink contains a solvent, a colorant and a resin, in which the resin is emulsionized or suspended. The ink jet printing method includes a drying step in which the ink is dried by the printing platen 2 after the ink is landed onto the medium 100. ## Claims ### Claim 1 An ink jet printing method using an ink jet printing apparatus comprising a head provided with a nozzle for discharging an ink onto a recording medium, and a heating means for heating the recording medium from a back side of a surface of the recording medium, which faces a surface of the head on which the nozzle is provided, wherein the ink contains a solvent, a colorant and a resin, in which the resin is emulsionized or suspended, and the ink is dried to form a coating, the ink jet printing method comprising: a drying step, in which the ink is dried by the heating means after the ink is landed on the recording medium; and an after-heating step, for heating the recording medium from the back side of the surface onto which the ink is landed at a downstream position from the heating means; wherein the ink jet printing apparatus further comprises: a blower, being disposed above the heating means and the blower blows an air to the surface of the recording medium onto which the ink is landed; wherein the blower has no means for heating the air. ### Claim 2 (depends on 1) The ink jet printing method according to claim 1, wherein the heating means is a mounting table on which the recording medium is placed. ### Claim 3 (depends on 1) The ink jet printing method according to claim 1, wherein the ink jet printing apparatus further comprises: a driving means for relatively moving the positions of the recording medium and the head; and a pre-heating table which is a mounting table on which the recording medium is heated, when the recording medium is placed in a position before the driving means causes the recording medium to move to a position where the recording medium faces the surface of the head on which the nozzle is provided. ### Claim 4 (depends on 1) The ink jet printing method according to claim 1, wherein the ink jet printing apparatus further comprises: a housing which includes the head therein, the housing further comprises a blower for blowing outside air to the surface of the recording medium in the housing onto which the ink is landed, and in the drying step, the blower blows air to the surface of the recording medium onto which the ink is landed. ### Claim 5 (depends on 4) The ink jet printing method according to claim 4, wherein the blower has no means for heating the recording medium. ### Claim 6 (depends on 4) The ink jet printing method according to claim 4, wherein the blower is provided on an opposite side to the position where the recording medium is placed as viewed from the head. ### Claim 7 (depends on 1) The ink jet printing method according to claim 1, wherein the resin is an acrylic resin. ### Claim 8 (depends on 1) The ink jet printing method according to claim 1, wherein the ink jet apparatus further comprises: a driving means for relatively moving the positions of the recording medium and the head; an after-heating table for heating the recording medium from the back side of the surface onto which the ink is landed when the recording medium is located downstream from the heating means because of the movement by the driving means; and an after-heating means for heating the recording medium from the opposite side to the after-heating table across the recording medium, wherein a second drying step is included in which the recording medium is heated by the after-heating table and the after-heating means after the drying step. ### Claim 9 An ink jet printing apparatus, comprising: a head provided with a nozzle for discharging an ink onto a recording medium, wherein the ink contains a solvent, a colorant and a resin, in which the resin is emulsionized or suspended, and the ink is dried to form a coating; a heating means for heating the recording medium from a back side of a surface of the recording medium, which faces a surface of the head on which the nozzle is provided; an after-heating means, for heating the recording medium from the back side of the surface onto which the ink is landed at a downstream position from the heating means; and a blower, being disposed above the heating means and the blower blows an air to the surface of the recording medium onto which the ink is landed; wherein the blower has no means for heating the air.
