on page 223.
If the overall tone is still too bright or too dark even after implementing Base Color
Tuning, adjust the black tone manually using Fine Color Tuning, and then
implement Basic color Tuning again. To brighten the overall tone, adjust the black
tone in Fine Color Tuning in the - direction, and to darken the overall tone, adjust
the black tone in Fine Color Tuning in the + direction.

a) Print the color tuning pattern.
b) Use the print results for the color tuning pattern to check the adjusted results.
If the pattern that seems most similar to the adjacent CMY mixed colors part and
single color K part in the “Highlight”, “Mid-Tone”, or “Dark” areas matches the
“Current” on the left of the color tuning pattern, the color balance adjustment is
complete.
Repeat steps 1 through 3 of this procedure in accordance with the results of your pattern
check.
