About tone curve

Tone Curve is a function to adjust brightness and contrast by controlling the input-output density curve for each of CMYK colors. Once tone curves adjusted in various conditions are registered in the image controller, those registered tone curves can be called and applied at the time of printing. Using Color Centro allows tone curve adjustment and registration to the image controller. You can also set tone curves using the printer driver.

Using Color Centro, you can adjust the tone curve (I/O density curve for CMYK colors) to adjust the color tone, 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 coloration, 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.
