A recording method comprising the steps in the following order of: correcting a curl of a recording medium by applying heat and pressure to the recording medium; and forming an image on the recording medium by jetting ink onto the recording medium.
Claims10
An ink jet recording apparatus comprising:
- a roll-set curl correcting section to correct a roll-set curl of a roll-state recording medium by applying heat and pressure, wherein the roll-set curl correcting section comprises a heating roller and a pressing roller installed to face the heating roller so as to nip the recording medium;
- a recording head to jet ink onto the recording medium;
- and
- a transporting section to transport an unrolled recording medium as the roll-set recording medium from a roll of rolled-recording medium wound around a core to the recording head via the roll-set curl correcting section so that the roll-set curl correcting section corrects the roll-set curl of the roll-set recording medium and thereafter the recording head jets ink onto the curl-corrected recording medium,
- wherein the pressing roller is a rubber roller and the heating roller is a metallic roller, and the hardness of the metallic roller is not less than 2 times the hardness of the rubber roller, and
- wherein the transporting section transports the recording medium such that the convex side of the roll-set curl of the recording medium faces the heating roller.
