摘要： A lighting device (23) irradiates a web under conveyance with light. The lighting device includes a light source (43), and an irradiation port (61) configured to open linearly in a widthwise direction of the web at an end portion facing the web. The irradiation port (61) is formed between first and second parallel portions (62b, 63b) where a first plate member (62) and a second plate member (63) parallelly face each other. The web under conveyance is irradiated with linear light. It is possible to provide a lighting device capable of irradiating only an inspection region of a sheet or a web with light.

摘要： A register error amount detection apparatus obtains the register error amounts between the colors of patterns printed on a printing product based on the positions of register marks in a captured image of the printing product. The register marks have different colors including a reference color and are printed in a line at intervals a in the vertical direction. The register marks all have the reference color and are printed in a line at the intervals a in the vertical direction at positions translated from the positions of the register marks by a distance b in the horizontal direction.
