Editing a gradation table
When you open the Gradation Tool, the default gradation table,
DefaultGradTable, is selected in the Gradation Table list, and is
displayed in the graph. This table serves as a baseline and
consists of a 45° gradation curve, with Brightness and Contrast set
to 0, and Contrast Center set to 50. All of the color separations are
selected.
The Gradation Table list includes four other predefined gradation
tables:
Cool: Blue tones appear clearer
Lively: Increases the color saturation
Saturated: Increases the strength (chroma or purity)
Sharp: Increases the contrast
Warm: Sets the hues in the low densities to a bright reddish color
Gradation tables that you create or edit also appear in the
Gradation Table list. When you select a gradation table, the
predefined settings are immediately applied to the processed job
that you are working with. The Separations buttons enable you to
select one, all, or any combination of separations to edit for a
specific gradation table. Selecting a specific separation enables
you to change the color balance for a specific tonal orange. When
you open the Gradations Tool window, all of the separations are
selected.
Note:
When you change gradation table definitions in the Gradation tool and
click Refresh, you will notice that the changes have affected the image in its
entirety. However, despite what you see in the Edited view, changes made to
the gradation tables do not affect spot colors.
1. From the Tools menu, select Gradation.
2. To edit the separations, do one of the following:
Click the All Colors button
to edit all the separations
simultaneously.
Click the individual separations you wish to edit—for
example, select the cyan separation only.
3. Click the curve in the graph to add a point, and then drag the
point to modify the separation.
The value appears in the Input or Output boxes.
4. To view gradation changes in your job, click Refresh.
Changes are automatically applied to the displayed image in
the After view.
