METHOD AND EQUIPMENT FOR COLORIMETRY OF PRINTED MATTER

摘要

PROBLEM TO BE SOLVED: To visually recognize a colorimetric point by making it possible to show a printed pattern containing the colorimetric point on a display. SOLUTION: On the occasion when printed matters moving consecutively on a printing line are metered by a colorimetric sensor, an image of an area on the printed matter containing the colorimetric point metered by the sensor is picked up by a camera and the picked-up image of the area is shown on the display, while a square mark M is shown in superposition at a position corresponding to the colorimetric point.
