Abstract:
1. A radiation failure inspecting method in a radiation unit including a plurality of radiation sections that each emit light to cure photo-curable ink and are arranged two-dimensionally in a predetermined direction and a direction intersecting the predetermined direction and emitting the light to the photo-curable ink on a medium while being moved in the predetermined direction relative to the medium, the radiation failure inspecting method comprising: scanning a radiation surface of the radiation unit to acquire red, green, and blue (RGB) data as read data in a state where a reading surface of the scanner faces the radiation surface of the radiation unit and the radiation unit emits the light; integrating the read data in a direction corresponding to the predetermined direction on the read data to acquire a value corresponding to a radiation energy of the light from the radiation unit; and determining that a radiation failure occurs in the radiation unit when the value corresponding to the radiation energy of the light is equal to or less than a threshold value.
