If you use Dot Gain values, apply the settings first, so that the curves are deflected from
their straight-line positions. Then make edits to the new curves. When you adjust Dot
Gain values, all existing points on the curve are removed. A warning dialog box allows
you to cancel Dot Gain settings before they are applied.
7. Use the plus and minus buttons to adjust brightness.
Changes to the brightness are reflected in the curve(s).
8. To adjust the curves directly, click and drag points on the curve or enter numbers into
the input and output boxes.
The graph maps the input percentage to the output percentage. (These percentages
refer to the size of the CMYK halftone dots.) The curve you selected appears, and
points along the curve are marked so you can adjust them.
