Inspection apparatus and inspection program

A non-transitory recording medium storing a computer readable inspection program that controls an inspection apparatus for inspecting printed matter on which an image is formed and including:

• a region extractor that extracts a first region, in which a character is formed, and a second region, in which the character is not formed, with reference to image forming image data used to form the image;
• and a defect detector that detects a defect in the first region and a defect in the second region in read image data obtained by reading the printed matter on which the image is formed by the image forming image data, the program causing a computer of the inspection apparatus to function such that
• the defect detector detects loss of a dot in the first region in the read image data as the defect and detects presence of a dot with a density equal to or greater than a predetermined density in the second region in the read image data as the defect.
