Abstract
An inkjet printer including an inkjet head with an ink discharging surface, a head scanning unit to drive the inkjet head to reciprocate along a first direction, and a pattern-printing control device to control printing a gap level pattern on a recording medium, is provided. The pattern-printing control device controls the inkjet head and the head scanning unit to print the gap level pattern including a plurality of unit patterns, in each of which the first linear pattern and the second linear pattern intersect each other, aligned along the first direction by manipulating the inkjet head to form a plurality of first linear patterns, which are formed to intersect the first direction, along the first direction, and to form a plurality of second linear patterns, which are formed to intersect the first linear patterns respectively at a same angle, along the first direction.
