6. Set the UCR Black properties.
This dialog box allows you to select a preset UCR curve, or
select Custom and adjust:
◆ Black Level Curve — the smoothness of gradations
between gray tones; a higher percentage yields smoother
gradations
◆ Maximum Black Ink — the amount of black ink used for a
given percentage of black called for in the image
Black and gray hues are created by printing with either Black
or a combination of Cyan, Magenta, and Yellow inks. You
can reduce total ink usage by a combination of creating
black with Black ink (a technique known as Under Color
Removal or UCR), and creating gray tones with Black ink
(Gray Component Replacement or GCR).
