Viewing the Color Calibration Sample Sheet and Gradation Correction Sheet

The Color Calibration Sample Sheet contains two color sample columns "sample 1" column for adjusting
highlights and "sample 2" column for adjusting midtones.
The gradation correction sheet contains: "gradation correction sheet 1" for adjusting highlights and
"gradation correction sheet 2" for adjusting midtones. Gradation correction sheet 1 is used for correction
1, while gradation correction sheet 2 is used for correction 2.
Color sample and correction values
The following explains how to view the color sample of the Color Calibration Sample Sheet and the
correction values of the gradation correction sheet.
This explanation uses setting K (black) as an example. The setting method for M (magenta) is similar.
For C/Y (cyan/yellow), the correction value is determined based on combinations of these two colors,
although panel settings are configured for each color separately.
• Hold the correction value (0 to 6) for "K" of the correction value setting sheet over the color
sample of gradation correction 1 of the Color Calibration Sample Sheet and find the corrected
color closest to that of the color sample. Then, enter the corresponding number using the
operation panel. The currently set correction value is printed in red.
