DETECTING METHOD FOR COLOR TONE AND DENSITY

摘要: PURPOSE:To accurately detect color tone and density without requiring skillfulness nor trial error by adding subtracting the coordinate values of a 2nd pattern which is closest in to 1st from gray. CONSTITUTION:A user selects patch 3 gray, e.g., Y (yellow) = -2 C (cyan) +1 among respective patches firstly. Then, 6 path selected scale 1 gray 5 wherein M (magenta), vary each seven stages. The Y=-1, M=-1, C=-1 are added Adjusting switches copying machine set Y, M, obtained as mentioned above adjust so that best reproducibility obtained. Consequently, detected.
