PURPOSE:To provide an automatic measurement device for measuring the overlap amount of halftone and its overlap direction of printed matter without individual variation such as in the visual measurement by an inspector. CONSTITUTION:This printed matter overlap amount measurement device consists of a microscope 3 for observing printed matter 1 and a half-tone image, TV camera 4, a device 6 to make an image signal from the TV camera 4 binary, a device 7 to connect binary data, a device 8 to measure the halftone center based on the connected process data and a device 9 to calculate an overlap amount from the halftone center, as constituent components of an image processing device 5. |
