Viewing the Color Calibration Sample Sheet and Gradation 
Correction Sheet
The color gradation correction value setting sheet contains two color sample col-
umns: the “Sample 1” column for setting the highlight part and the “Sample 2”
column for setting the middle part.
Similarly, there are two gradation correction sheets: “Gradation correction sheet
1” for setting the highlight part and “Gradation correction sheet 2” for setting the
middle part. Gradation correction sheet 1 is used for calibration 1, while Grada-
tion correction sheet 2 is used for calibration 2.
❖ Color sample and correction values
The following explains how to use the color sample of the Color Calibration
Sample Sheet and the correction values of the gradation correction sheet.
This explanation uses K (black) as an example. The setting method for M (ma-
genta) is similar. For C/Y (cyan/yellow), the correction value is determined
based on combinations of these two colors, although settings are made for
each color.
❒ Compare the K correction value (0-6) of gradation correction sheet 1 with
the K color sample of the Color Calibration Sample Sheet. Determine the
color that matches the color sample the closest, and then set the correction
value of that color using the control panel. The currently set correction val-
ue is printed in red.
