Abstract
In order to settle a phenomenon that a quantity of jetted ink increases at the end of an image and a density increases in a shear-mode ink jet head, in a three-split driven head, a first group prints so that a diameter of a dot is reduced by reducing the quantity of jetted ink as dots at both ends, a second group similarly prints, and a third group also similarly prints. Since three dots at both ends in a main scanning direction of an acquired image are smaller than dots in the middle, the phenomenon that a quantity of jetted ink increases at the end of the image and density increases is reduced.
