Gradation Tool

Sometimes you need to perform tone corrections when printing a job. These 
changes in gradation can include brightness, contrast, and color balance 
adjustments throughout the tone range of an entire image, or in specific tone ranges. 

Gradation tables you create using the Gradation tool are added to the gradations list 
in the 

Color tab, and may be applied to print jobs. The Spire CX260 also enables you 

to visually check the effect of different gradation adjustments on RTP jobs prior to 
printing.

With the Spire CX260 Gradation tool, you can apply the default gradation table or 
another pre-configured gradation table to a job. You can also edit an existing table 
and save your changes. Gradation is an interactive function and changes are 
automatically applied to the displayed image.

The Gradation tool is used to create and edit gradation tables and to check the effect 
of different gradation adjustments on specific RTP jobs. These tables can then be 
applied to your jobs during job processing for tailored gradations.

Note:  You can edit an existing gradation table, but you can not overwrite the 
default gradation table, 

DefaultGradTable.
