Adobe Dei nes Rendering Intents as Follows:
Perceptual: The goal of this intent is to preserve the visual relationship
between colors, so it is perceived as natural to the human eye, even
though the color values themselves may change. This intent is suitable for
photographic images with lots of out-of-gamut colors. This is the standard
rendering intent for the Japanese printing industry.
Saturation: Attempts to produce vivid colors in an image at the expense
of color accuracy. This rendering intent is suitable for business graphics like
graphs or charts, where bright saturated colors are more important than the
exact relationship between colors.
Relative colorimetric: Compares the extreme highlight of the source color
space to that of the destination color space and shifts all colors accordingly.
Out-of-gamut colors are shifted to the closest reproducible color in the
destination color space. “Relative colorimetric” preserves more of the original
colors in an image than “Perceptual”. This is the standard rendering intent for
printing in North America and Europe.
Absolute colorimetric: Leaves colors that fall inside the destination
gamut unchanged. Out-of-gamut colors are clipped. No scaling of colors
to destination white point is performed. This intent aims to maintain color
accuracy at the expense of preserving relationships between colors and is
suitable for prooi ng to simulate the output of a particular device. This intent
is particularly useful for previewing how paper color af ects printed colors.
