Color Management Overview
Relative (Default of CMYK)
After dynamic range compression is done, colors that can not be reproduced will be converted,
lightness will be sustained as much as possible, and saturation will be decreased. This is not
intended for conversion of wide dynamic-ranged images, or high key and low key images.
Saturation
The saturation option is specific for pixels in images. When saturation is changed, it changes
the hue and lightness of an image.
It is not recommended to change this option for photos, but is useful for conversion of graphics
and charts for presentations.
Absolute
The Absolute option allows colors of reproducible areas to be converted correctly. When colors
are converted, lightness is similar to original and saturation will be decreased. For colors in areas
that are not reproduced, halftones will decrease significantly. It is not recommended to choose
this option for conversion of wide dynamic-ranged images, or high key and low key images.
