Abstract
An ink jet printing apparatus, for each level, employs a plurality of density patterns to prevent cancellation of a granularity reduction effect that has been provided by an increase in resolution. Specifically, when determining an arrangement of dot-on areas in the density pattern, the dot-on areas is not located in the areas of a first row of the each of the plurality of density patterns. Thereby, whitish areas appear with the same cycle as a use cycle of the density patterns in a longitudinal direction and thus the whitish areas is not unevenly located. As a result, granularity is prevented from increasing.
