An inspection device configured to inspect a printed image printed on a surface of a transparent base material, the device comprising: a first light-emitting unit configured to emit light from a print-surface side of the transparent base material toward the transparent base material; an imaging unit configured to image the transparent base material from an opposite side of the print-surface side of the transparent base material; an inspection processing unit configured to inspect quality of the printed image based on a captured image obtained by the imaging unit; and a second light-emitting unit configured to emit light from the opposite side of the print-surface side of the transparent base material toward the transparent base material, wherein light emitted from the first light-emitting unit is transmitted through the transparent base material and incident on the imaging unit, light emitted from the second light-emitting unit is reflected by the transparent base material and incident on the imaging unit, the imaging unit is configured to image the transparent base material from the opposite side of the print-surface side of the transparent base material while the first light-emitting unit and the second light-emitting unit emit light, the printed image includes a process-color image that is formed by inks of a plurality of process colors, and a non process-color image that is formed by an ink of a non -process color different from the plurality of process colors and that covers the print-surface side of the process-color image, the plurality of process colors includes cyan, magenta, yellow, and black, and the non-process color is white. a first light-emitting unit configured to emit light from a print-surface side of the transparent base material toward the transparent base material; an imaging unit configured to image the transparent base material from an opposite side of the print-surface side of the transparent base material; an inspection processing unit configured to inspect quality of the printed image based on a captured image obtained by the imaging unit; and a second light-emitting unit configured to emit light from the opposite side of the print-surface side of the transparent base material toward the transparent base material, wherein light emitted from the first light-emitting unit is transmitted through the transparent base material and incident on the imaging unit, light emitted from the second light-emitting unit is reflected by the transparent base material and incident on the imaging unit, the imaging unit is configured to image the transparent base material from the opposite side of the print-surface side of the transparent base material while the first light-emitting unit and the second light-emitting unit emit light, the printed image includes a process-color image that is formed by inks of a plurality of process colors, and a non process-color image that is formed by an ink of a non -process color different from the plurality of process colors and that covers the print-surface side of the process-color image, a process-color image that is formed by inks of a plurality of process colors, and a non process-color image that is formed by an ink of a non -process color different from the plurality of process colors and that covers the print-surface side of the process-color image, the plurality of process colors includes cyan, magenta, yellow, and black, and the non-process color is white.
