3.4.11 DEF REND INTENT
This option menu controls the default rendering intent for different types of IPDS data (Images, Text and
Graphics). The following type of intent can be selected:
• Perception Perceptual Rendering Intent. Attempts to preserve appearance by
maintaining color relationships; typically used to render continuous-tone
images.
• Relative Colorim Relative Colorimetric Rendering Intent. Maps white point of source color
to white point of output media; colors ‘look right’ but may not be accurate
colorimetrically. Typically used for vector graphics or images.
• Saturation Saturation Rendering Intent. Attempts to generate vivid, saturated colors,
even at the expense of color accuracy; typically used for business
graphics.
• Absolute Colorim Absolute Colorimetric Rendering Intent. Does not map white point of
source color to white point of output media. If source white is bluish and
media white is yellowish, system adds cyan to simulate blue on output
medium. Colors are accurate colorimetrically but may not ‘look right’.
Typically used for logos or proofing.
