METHOD FOR ADJUSTING COLOR DENSITY IN PRINTER

摘要

PROBLEM TO BE SOLVED: To provide a method for acceptance and authentication of a printing reference to be sufficient with a less labor than that in a known prior art.SOLUTION: A method for adjusting color density in a printer executes the steps of: printing a test version on printed matter 20 and setting conscious color density deviation from intended target color density in an ink zone provided in an ink device 16 of a printer 12; performing output control of color density previously adjusted and color density deviation set and adjusted with color measuring instruments 21, 24 in accordance with a target value in a state where the printed matter is wet; performing color measurement on the dried printed matter with the color measuring instruments; comparing a color measuring value detected in the dried state and a print original image of the test version with a computer 160; and utilizing the color density having the minimum deviation to the intended target color density and belonging to the ink zone as the target color density for a printing process.
