USING PHOTOSHOP LIGHTROOM 2 30 Workspace and setup Output color profiles When you print a photo in Lightroom, you can choose to convert the colors to more closely match the color space of the printer, paper, and ink you are using. For information on working with printer color profiles, see "Set print color management" on page 159. Lightroom automatically exports images in the Slideshow and Web modules using the sRGB profile so that the color looks good on the majority of computer monitors. Calibrate and profile your monitor You can calibrate your monitor and create a profile that specifies its color characteristics using monitor profiling software and hardware. When you calibrate your monitor, you are adjusting it so that it conforms to a known specification. Once your monitor is calibrated, the profiling utility lets you save a color profile. 1 If you are calibrating a CRT monitor, make sure it has been turned on for at least a half hour. This gives it sufficient time to warm up and produce more consistent output. 2 Set the ambient lighting in your room to be consistent with the brightness and color of the room lighting you'll be working under. 3 Make sure your monitor is displaying thousands of colors or more. Ideally, make sure it is displaying millions of colors or 24-bit or higher. 4 Remove colorful background patterns on your monitor desktop, and set your desktop to display neutral grays. Busy patterns or bright colors surrounding a document interfere with accurate color perception. 5 Calibrate and profile your monitor using third-party software and measuring devices. In general, using a measuring device such as a colorimeter along with software can create more accurate profiles because an instrument can measure the colors displayed on a monitor far more accurately than the human eye. Note: Monitor performance changes and declines over time; recalibrate and profile your monitor every month or so. If you find it difficult or impossible to calibrate your monitor to a standard, it may be too old and faded.

Output color profiles
When you print a photo in Lightroom, you can choose to convert the colors to more closely match the color space of
the printer, paper, and ink you are using. For information on working with printer color profiles, see “
Set print color
management
” on page
159.
Lightroom automatically exports images in the Slideshow and Web modules using the sRGB profile so that the color
looks good on the majority of computer monitors.
Calibrate and profile your monitor
You can calibrate your monitor and create a profile that specifies its color characteristics using monitor profiling
software and hardware.
When you calibrate your monitor, you are adjusting it so that it conforms to a known specification. Once your monitor
is calibrated, the profiling utility lets you save a color profile.
1
If you are calibrating a CRT monitor, make sure it has been turned on for at least a half hour. This gives it sufficient
time to warm up and produce more consistent output.
2
Set the ambient lighting in your room to be consistent with the brightness and color of the room lighting you’ll be
working under.
3
Make sure your monitor is displaying thousands of colors or more. Ideally, make sure it is displaying millions of
colors or 24-bit or higher.
4
Remove colorful background patterns on your monitor desktop, and set your desktop to display neutral grays. Busy
patterns or bright colors surrounding a document interfere with accurate color perception.
5
Calibrate and profile your monitor using third-party software and measuring devices. In general, using a measuring
device such as a colorimeter along with software can create more accurate profiles because an instrument can
measure the colors displayed on a monitor far more accurately than the human eye.
Note:
Monitor performance changes and declines over time; recalibrate and profile your monitor every month or so. If
you find it difficult or impossible to calibrate your monitor to a standard, it may be too old and faded.
Most profiling software automatically assigns the new profile as the default monitor profile. For instructions on how
to manually assign the monitor profile, refer to your operating system’s Help.
Install a color profile
Color profiles are often installed when a device is added to your system. The accuracy of these profiles (often called
generic profiles
or
canned profiles
) varies from manufacturer to manufacturer. You can also obtain profiles from a
custom profile service, download profiles from the web, or create
custom profiles
using professional profiling
equipment.
In Windows, right-click a profile and select Install Profile. Alternatively, copy the profiles into the
WINDOWS\system32\spool\drivers\color folder (Windows
XP).
In Mac
OS, copy profiles into the /Library/ColorSync/Profiles folder or the
/Users/
username
/Library/ColorSync/Profiles folder.
After installing color profiles, be sure to restart Adobe applications.
