PROBLEM TO BE SOLVED: To properly print without deteriorating an image, even when a non-discharge picture element is included in a fine line.SOLUTION: An inkjet printer comprises a non-discharge table storage part 309 for storing a non-discharge table, a complementary table storage part 304 for associatively storing an ink quantity of a non-discharge picture element, the complementable direction and a complementary ink quantity as a complementary table and an image processing part 303 for correcting drop data so as to complement ink by the complementary ink quantity to a determined complementary picture element, by determining a peripheral picture element positioned in the complementable direction among the peripheral picture elements and being positive in a drop number, as the complementary picture element being an object picture element for complementing the drop number, based on the drop number of an extracted non-discharge picture element and the drop number of the peripheral picture element and the complementary table stored in the complementary table storage part 304, by extracting the drop number of the non-discharge picture element and the drop number of the peripheral picture element of the non-discharge picture element from the drop data of a printing job based on the non-discharge table stored in the non-discharge table storage part 309.SELECTED DRAWING: Figure 3 |
