How often should I calibrate?
Just as you may want to change the oil in your vehicle every 3000 miles, or
wax and edge your skis to maximize their optimum performance periodically,
a monitor needs the same kind of regular tune-ups and care to perform well
over time.
• Monitors should be calibrated every 2-4 weeks depending on the amount
of usage.
• For the most accurate results, be sure to let the monitor warm up for at least
30 minutes in order to stabilize before calibration is performed.
• Periodic calibration will help maintain consistent color display on the
monitor over time.
Settings for calibration will vary depending on your output. If you are
working in your own closed loop system - that is your own camera, printer
and monitor - our best recommendation for most users would be to work
with daylight settings, 6500 K and Gamma 2.2 as a starting point. This setting is
usually best for working with Adobe 1998. If working with Piezography inks,
results have often been more accurate using a D-50 or 5000 K calibration
setting. You will need to experiment to i nd the best settings consistent with
your workl ow and output variables.
IV. Software Policies
Set Photoshop color management policies and color
working spaces
The next step in our color management system is to set up the software
color policies to interpret the color information correctly on your calibrated
monitor! Just like the choices we have in setting the digital camera to a
specii c color capture space, we will want to set Photoshop policies to match
the camera capture settings.
There are very few image browsers that of er control over the viewing color
space. Instead, most software applications can only display the images in the
color space of the operating system. In Windows XP, as well as most older
versions of Windows, that would be sRGB (remember that is the smallest
working space, which is not recommended for print reproduction work).
Images captured in the Adobe RGB working space will appear on screen
somewhat l at and desaturated when (incorrectly) viewed in sRGB.
Photoshop is, however, an incredibly color savvy software that of ers the
best environment in which we can view Adobe RGB images, ProPhoto RGB,
or images dei ned by any other color space. You can, with accurate color
display for each space, simultaneously view an sRGB image in a side by side
comparison with an Adobe RGB image.
