Abstract
PURPOSE: To make it possible to measure pattern area precisely even if an offset printed is uneven by mounting a printing plate for offset print on a longitudinal inclined stage and by scanning and detecting the pattern of the printing plate by a scanner.
CONSTITUTION: Front panel 71 of measuring device 70 is a bevel and at its center part, stage 74 for mounting printing plate 20 is arranged. Between racks 31 and 73, box-shaped scanner 10A enclosing the photodetector and having required circuit constitution incorporated is arranged and the photodetector takes a linear scan on printing plate 20. A detection signal obtained by this scan is inputted to the arithmetic processor to find pattern area.
