<P>PROBLEM TO BE SOLVED: To enable inspection on a quality of a picture printed on three kinds of print sheets such as a transparent film, a normal print sheet and a vapor deposition sheet, using a single configuration, so as to reduce cost, to lighten a burden of an operator and to prevent waste of print materials, in a printing quality inspection device. <P>SOLUTION: In a printing quality inspection device, if a to-be-printed member is a vapor deposition sheet 2A, light radiated from a light source 22 and reflected at a reflection point 24a of a diffusion reflection plate 24 irradiates an inspection point 2a, and enters a camera 23 through an incident route 32. If the to-be-printed member is a normal print sheet, the light reflected at a diffusion reflection surface of the to-be-printed member enters the camera 23. If the to-be-printed member is a transparent film, the light penetrating the transparent film is mirror-reflected on a surface of an impression cylinder 11 and enters the camera 23. <P>COPYRIGHT: (C)2012,JPO&INPIT |
