PROBLEM TO BE SOLVED: To lessen deterioration of a granularity of recording images due to bleeding of recording dots by a dark ink by sequentially overlapping from ink of a higher ink dye concentration onto a recording medium to record ink drops. SOLUTION: At the time of recording images onto a recording medium by scanning a recording head unit, recording heads are arranged in an arrangement from a lower ink dye concentration to a higher ink dye concentration from the upstream to the downstream of a scanning direction. When recording ink drops are recorded on the recording medium 6, recording ink drops are recorded in the order of recording inks from a dark Bk ink BKN: 121→...→a light Bk ink BKT: 125→...→a light Y ink YT: 128. That is, the recording ink drops are recorded on the recording medium first from the recording ink of the higher ink dye concentration. In consequence of this, recording dots of the light black ink recorded later bleed and are increased in diameter, thereby lessening deterioration of a granularity of recording images. |
