Editing Gradation Tables
When you open the Gradation Tool window, the default gradation
table,
DefaultTable
, 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
•
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 range.
When you open the Gradations Tool window, all of the separations
are selected.
