Tone Curve Adjustment
Overview
Tone Curve Adjustment makes adjustments using the input/output density curve for each color of CMYK.
You can adjust the brightness and contrast of the entire image.
Place a point on a graph, and drag it to the appropriate position for adjustment. The adjusted image is displayed on the preview screen, so you can perform operations while checking the image.
A tone curve can be saved in both the Image Controller and the computer.
The tone curve saved in the Image Controller can be applied to output.
The target tone curve can be set for each job from the printer driver.
Tips
- In [Tone Curve Adjustment], you can make adjustments using the curve displayed in [Brightness/Contrast], [Adjust Each Color], or the graph field. For details, refer to Graph Field.
