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, and 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 a combination 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.
Reading the gradation correction sheet
The printed gradation correction sheet is read as shown below.
Comparing the gradation correction sheet and correction value of each color, K (black), M (magenta), and C (cyan)/Y (yellow) determine the required gradation correction and configure settings using the control panel.
K (black) correction values
Used to adjust the color printed when only black toner is used. The currently set correction value is printed in red.
M (magenta) correction values
Used to adjust the color printed when only magenta toner is used. The currently set correction value is printed in red.
C (cyan)/Y (yellow) correction values
Used to correct the colors printed when cyan and yellow are used. 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.
Setting value
The value displayed is the one currently set when the gradation correction sheet is printed. This value corresponds to the value set on the control panel.
