Abstract: In an image processing apparatus, a processor sets a target printing method for printing a target image to one of a bidirectional printing method and a unidirectional printing method. In a case where the bidirectional printing method is set as the target printing method: the processor executes both a first generation process and a second generation process. The first generation process generates first partial print data by converting a set of partial image data using a first color conversion profile. The second generation process generates second partial print data by converting another set of partial image data using a second color conversion profile. In a case where the unidirectional printing method is set as the target printing method, the processor executes a third generation process generating third partial print data by converting a set of partial image data using a third color conversion profile.

Abstract: In an image processing device, a controller is configured to perform: selecting; generating; and outputting. The selecting selects a target partial image one by one from a plurality of partial images. The target partial image is represented by target partial image data.

The partial print forms the target partial image while moving a print head in a printing direction. The partial print forms the target partial image while moving a print head in a printing direction. The image process includes a color conversion process. The color conversion process is executed on the target partial image data using one of a first profile and a second profile selected in accordance with the printing direction set for the partial print. The outputting outputs the partial print data to the printer.

Abstract: An image processing device is communicable with a printer and includes a controller. The printer is configured to repeatedly and alternately execute a partial print and a sub scan to form an image. The image is made up of a plurality of partial images arranged in a sub scanning direction. The partial print forms a target partial image while performing a main scan.

The color conversion profile is selected from first and second profiles respectively corresponding to the first and second directions. The outputting outputs the partial print data and direction information specifying the printing direction.
