Edit response using curves

You can edit the response curves in the Color Adjust pane (for color output) or Curve Edit pane (for black-and-white output) to make precise edits to a job. This feature lets you customize the response curve for all the color curves together, for an individual color separation in a color job, or for the gray of a black-and-white job.

For a black-and-white job, edits to the gray response curve apply to all pages of the job.

Note: After you make curve edits for a color job, save the job before you switch to the Color Wheel tab. Otherwise, all of your curve edits are lost.

Edit a curve graphically

For a color job, click the Curves tab in the Color Adjust pane.
If necessary, adjust how the color curves are displayed:
- To select a specific color curve, select the color from the Channels menu.
- To select all the color curves together, select All Channels from the Channels menu.
Note: When All Channels is selected, use the page up and page down keys to switch between the color curves.
For a color job or black-and-white job, do any of the following:
- To add a point on the curve, click anywhere on the curve.
- To edit a curve, drag a point on the curve to the desired response value.
Note: In Windows, you can select a point and use the arrow keys to move the point 1% in any direction, or to move a large amount, hold down the shift key and press an arrow key.
- To delete a point on a curve, select the point and press Delete.
  
  You can also select a point and drag it over the point you want to delete.
- In Windows, move from point to point by selecting one point on the curve and using shift-page up and shift-page down.

Edit color curve data

For a color job, click the Curves tab in the Color Adjust pane and then click Edit Curve.
In the table that appears, edit the numeric values.
Each row of the table corresponds to an edit point in the graph.
Do any of the following:
- To display a predefined set of rows, select the set from the Control Points list.
- To add a row, type in the empty row.
- To delete a row, click anywhere in the row and click Delete Row.
