Abstract:
An ink jet recording method comprising the steps of: ejecting droplets of two liquids of a reaction solution and an ink composition through respective ink jet recording heads; and depositing the droplets of the ink composition and the droplets of the reaction solution onto a recording medium so that the reaction solution comes into contact with the ink composition on the recording medium, thereby performing printing,the reaction solution containing a reactant capable of functioning to agglomerate ingredients of the ink composition,the ink jet recording heads being reciprocated on the recording medium, the ink composition being deposited onto the recording medium both at the time of motion of the ink jet recording head in the forward direction and at the time of motion of the ink jet recording head in the backward direction, while the reaction solution is deposited onto the recording medium only at the time of motion of the ink jet recording head in the forward or backward direction, wherein the density of nozzles in the recording head is n dpi and the recording medium is carried by 1/(2n) inch in the sub-scanning direction in a period between printing at the time of motion of the recording head in the forward direction and printing at the time of motion of the recording head in the backward direction, whereby an image is printed with a resolution of 2n dpi.
