Image Quality: Adjusting the Tone Curve

Using Color Centro, you can adjust the tone curve (I/O density curve for CMYK colors) to adjust the brightness and contrast of the whole page.

The adjusted tone curve can be registered in the image controller and called to be applied when printing.

Using sample data (sample B), you can check the procedure during the actual operation.

• Meaning and Purpose of Tone Curves

By operating the I/O density curve for CMYK colors, you can adjust the reproduction of brightness, contrast, and gradation.

It is useful for changing the brightness and/or contrast of photographs so as to suit the user's preference.

By registering the adjusted tone curve in the image controller, you can call this data at any time for any print.
