1. An inkjet printing device comprising:
a transport path for transporting a sheet as a box-making material to be assembled into a corrugated box including a plurality of wall portions, in a transport direction; and
an inkjet head that is disposed to face a surface of the sheet in the transport path and configured to print a predetermined print pattern in a predetermined printing range in an intersecting direction which is a direction intersecting the transport direction along the surface of the sheet and corresponds to a width direction of the sheet, wherein
the transport path transports, when the inkjet printing device is operating, the sheet in the transport direction in a posture where planned processing locations, where processing for making the corrugated box is planned to be performed, extend in the transport direction, and where the planned processing locations are aligned in the intersecting direction; and
the one inkjet head is disposed such that the printing range extends over only one of the planned processing locations.
