Zusammenfassung:	An imaging apparatus includes a print engine having a printhead that generates ink drops, and a printhead carrier that carries the printhead in a first direction and in a second direction opposite the first direction. A controller determines an initial print direction based on ink drop information obtained by printing patches in the first direction and in the second direction, wherein the ink drop information includes a respective chromatic value of each of the patches. The controller is operatively coupled to the print engine to print an image based on the initial print direction.
