Inclined surfaces of a first protrusion and a second protrusion of a first inkjet head and inclined surfaces of side walls of a head cap abut against each other, but other portions of the first inkjet head do not abut against the head cap. Specifically, the head cap 510 is not abutted against the lower surface 133 of the first inkjet head 130, and is also not abutted against the ejection surfaces 134A and 135A of the first protrusion 134 and the second protrusion 135. In particular, the side walls are formed to a shape so as not to overlap the ejection surfaces when viewed in the vertical direction, whereby the head cap does not abut against the ejection surfaces.

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 generating generates partial print data for a partial print by executing an image process on the 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.
