342 Chapter 7 – Color Workflow
There are several methods that can be used when translating colors
from one color space to another. These methods are called Rendering
Intents because they are optimized for various uses. When working
with ICC profiles, it is important that you select the Rendering Intent
that best preserves the important aspects of the image. Each rendering
method specifies a CRD for color conversions. You can modify the
rendering method to control the appearance of images, such as prints
from office applications or RGB photographs from Photoshop.
•
Relative Colorimetric:
a rendering intent method in which colors that
fall within the output color space remain the same. Only colors that fall
outside are changed to the closest possible color within the output
color space.
When using this method, some closely related colors in the input color
space can be mapped to a single color in the output color space. This
reduces the number of colors in the image.
•
Absolute Colorimetric:
a rendering intent method similar to Relative
Colorimetric except that it does not make adjustments according to the
white point. In this method, colors that do not fit within the output
color space are rendered at the extremes of the output color space.
Colors that fall inside the output color space are matched very
accurately.
This method is valuable for representing “signature colors“. Colors that
are highly identified with a commercial product such as the cyan in the
Creo logo.
•
Saturated (presentation)
- a rendering intent method which scales all
colors to the strongest saturation possible. The relative saturation is
maintained from one color space to another.
