• CMYK (0-100%)

of the color value entered.
– Large: A substitute color replaces any color that falls within the nearest +/- 0.5% of
the color value entered.

– Small: A substitute color replaces any color that falls within the nearest +/- 0.25 of

Color substitution
A color substitution takes place when a substitute color is defined with a different set of
CMYK values for the same value-name as the original color.
The following color examples show how a substitution works.
• <100, 0, 0, 0> for the CMYK values (cyan)
Original color:
• <0, 100, 100, 0> (red)
Substitute 1:
• <100, 0, 100, 0> (green)
Substitute 2:
N : In the examples, the extreme values and terms "red" and "green" are used for
OTE
illustrative purposes only. In practice, color substitution is not used for extreme color
shifts.
The following table shows color substitution with different sets of CMYK values assigned
to the same original color.
