Input Color Conversions Overview
Administrator access level only!
The Input Color Conversions overview lists all available input conversions.
Input Color Conversion list
Select a conversion in the list to see more information in the pane on the right.
Convert Objects to Document Intent
These setting define how color values in CMYK, RGB and Gray objects are converted to the Document Output Intent.
Apply Black Point Compensation
Apogee uses a built-in algorithm to adjust for differences in the black points. Select the color space or spaces you want to apply this conversion to: RGB, CMYK, Gray.
Gray Conversion: Convert as pure K
Select this option to render a gray image in K only.
CMYK Profile Link Exception
Choose an exception from the drop-down list:
•None
•Keep 100% K
•Normal
•Preserve K
•Preserve Pure Colors
•other exceptions as listed in the Profile Link Exceptions resource
Defaults
If the input tagging sets the rendering intent to From Input but no color values are specified, a default rendering intent is applied.
Rendering Intent
Choose a default rendering intent from the drop-down list:
Relative Colorimetric
A colorimetric conversion, tries to maintain the exact relationship (Smallest Delta E), between in-gamut colors, while out of gamut colors will be clipped. With Relative Colorimetric RI the white point from source color space is mapped to the white point of destination, this means that white stays white. No ink will be placed in white areas.
Perceptual
Perceptual aims to preserve the visual relationship between colors so it is perceived as natural to the human eye. The relationship between out of gamut colors is maintained. This can result in inaccuracies for in gamut colors as well.
Saturation
Saturation tries to produce vivid colors in an image at the expense of color accuracy.
Absolute Colorimetric
Absolute Colorimetric rendering intent is similar to Relative Colorimetric, except that here the white point of the two profiles is preserved. White of source color space is simulated with CMYK values from the destination color space. The consequence is that every white object/area is covered with certain ink amounts.
NOTE: The result of choosing a rendering intent depends on the graphical content of documents and on the profiles used to specify color spaces. Some profiles produce identical results for different rendering intents. Differences between rendering intents are apparent only when you print a document or convert it to a different working space.
