PROBLEM TO BE SOLVED: To provide a method for inspecting a luminous printed matter capable of imaging a streak one by one distinctively even in a case where an inspection object is a printed pattern composed of streaks made of photo-luminescent ink having bulges.SOLUTION: A method for inspecting a luminous printed matter images a printing pattern composed of luminous streaks having a plurality of bulges provided on a substrate using an inspection device having at least coaxial epi-illumination and a line camera, obtains an image, and performs quality determination of the printed matter by comparing the obtained image with a normal image that is pre-stored and composed of a plurality of streaks. The method includes at least an irradiation direction setting process, an irradiation process, a reflected image photographing process, and a determination process. |
