B Calibrating Your Aperture System
The accuracy of your display and printer’s ColorSync profile is
critical to ensuring accurate color reproduction.
Aperture is a powerful digital image adjustment application, but its power is limited to
the accuracy of the devices that display and print your images. This appendix provides
information about color calibrating cameras, displays, and printers. Whether you use a
desktop inkjet printer or a professional lab prints your images, calibrating your display
and print devices and using custom profiles ensure predictable colors in your prints
every time.

An Overview of Color Management
Maintaining calibrated displays and printers is essential to good color management.
Every display and printer is unique. As these devices age, environmental conditions,
system configurations, and changes in materials such as inks and paper affect the
devices’ ability to reproduce color. Changes in the way a device reproduces color over
time are known as drift. Maintaining good color management ensures that when you
make adjustments to the colors in your digital images in Aperture, these colors are
faithfully reproduced on your display screen and on the printed page.
