Changing gradation with the CMYK Curves
If you are used to working directly in CMYK, the CMYK Curves let you change the gradation by
manipulating the CMYK values directly. See M
odifying images directly in CMYK.
Changing gradation with the RGB Curves
ColorQuartet’s Gradation function is defined in terms of CMYK or LCH color values. If you are
outputting images in RGB form – for example, on an RGB-based printer or proofer or for use in
an on-screen application such as a web site – the RGB Curves let you change the gradation
directly in RGB. See M
odifying images directly in RGB.
