Select Ink Black to use the relative colorimetric rendering intent with no black point
compensation. The intent of Relative Colorimetric is identical to that of Absolute Colori-
metric except for the following difference: relative colorimetric compares the
white
point
(extreme highlight) of the source color space to that of the destination color
space and shifts all colors accordingly. Relative colorimetric can be more accurate if the
image’s profile contains correct white point information. This is the default rendering
intent used by all predefined color management configurations.
•
Select Paper White to use the absolute colorimetric rendering intent. Absolute Colori-
metric rendering intent leaves colors that fall inside the destination gamut unchanged.
Turning this off (Relative Colorimetric) maps Paper White to the whitest value that the
monitor can display.Turning this on (Absolute Colorimetric) attempts to reproduce the
actual color and tone of the document on the monitor. Thus, if the paper is darker or a
different shade, the color on the monitor will appear somewhat muted, offering a more
realistic rendition of how the color actually reproduces, especially in the case of limited-
gamut media such as uncoated stock.
If you select Simulate Paper White, Simulate Ink Black is automatically selected and grayed
out because it is required.

Creating a viewing environment
Your work environment influences how you see color on your monitor and on printed
output. For best results, control the colors and light in your work environment by doing
the following:
•
View your documents in an environment that provides a consistent light level and color
temperature. For example, the color characteristics of sunlight change throughout the
day and alter the way colors appear on your screen, so keep shades closed or work in a
windowless room. To eliminate the blue-green cast from fluorescent lighting, consider
installing D50 (5000 degree Kelvin) lighting. Ideally, view printed documents using a
D50 lightbox.
•
View your document in a room with neutral-colored walls and ceiling. A room’s color
can affect the perception of both monitor color and printed color. The best color for a
viewing room is polychromatic gray. Also, the color of your clothing reflecting off the
glass of your monitor may affect the appearance of colors on-screen.
•
Match the light intensity in the room or lightbox to the light intensity of your monitor.
View continuous-tone art, printed output, and images on-screen under the same
intensity of light.
•
Remove colorful background patterns on your monitor desktop. Busy or bright patterns
surrounding a document interfere with accurate color perception. Set your desktop to
display neutral grays only.
•
View document proofs in the real world under which your audience will see the final
piece. For example, you might want to see how a housewares catalog looks under the
incandescent light bulbs used in homes, or view an office furniture catalog under the
fluorescent lighting used in offices. However, always make final color judgments under
