Ink jet recorder

Abstract

Abstract PURPOSE:To obtain sufficient picture element resolution, by providing a plurality of inks each having different densities, the ink drop jetting measures independently for each ink and the control measures of respective ink jetting measures corresponding to unit picture element preliminarily set. CONSTITUTION:When an electric signal is sent to the ink jet terminal for black ink S, a black ink drop D1 flies toward a recording paper 9 from an ink jet head H1 and forms a black dot on the surface of paper. When an electric signal is sent to the ink jet terminal for thin black ink S2, a thin black ink drop D2 flies toward the recording paper 9 from an ink jet head H2 and forms a thin black dot. The recording paper 9 can be vertically moved by the mechanism for feeding paper and the ink jet headers H1 and H2 can be horizontally moved by the carriage loaded with them. Then, ink is shot to an arbitrary position by the ink shot timing position control measures or the like. Further, when the density of ink has K classes and the maximum recording reflection density is Dmax, each recording reflection density shall be (n/K).Dmax.
