A lot of us might not care that the color on our screens doesn't precisely match reality, but for most designers color matching is a crucial part of their work. That's why they use monitor calibration systems like the new La Cie blue eye pro Proof Edition (US$429.99) to make sure that what they see on the screen is exactly what they'll see on a finished product.

The blue eye pro Proof Edition is the blue puck that you see on the left side of the photo illustration at right. It supports monitor calibration and profiling and can provide UGRA (Swiss Center of Competence for Media and Printing Technology) soft proof testing and reporting.

La Cie has announced immediate availability of the blue eye pro Proof Edition, which is compatible with the Adobe Creative Suite, QuarkXPress, Aperture and other design and photography applications. it requires Mac OS X 10.4.5 or later on Intel Macs, as well as a USB port for connectivity.

Like virtually all mobile computer manufacturers, Apple recommends that users calibrate their laptop batteries every few months, as Scott pointed out a couple of years ago. Unlike many manufacturers, however, Apple does not include a utility to automatically perform a calibration. Given Apple's uncanny ability to make things user-friendly, this seems like a bit of a glaring oversight.

What are the benefits of calibration? Primarily the goal is to ensure that the microprocessor in your battery provides an accurate estimate of how much time you have left on the battery. Over time it can lose track of just how much juice your battery has in it, and calibration gives it a very accurate reading on the battery's health.

Older battery technologies also benefited from a process called conditioning, which was typically performed the same way as a current battery's calibration process. In a nutshell, you fully charge the battery, fully discharge it, then fully charge it again. It's unclear whether modern lithium batteries gain anything in an actual capacity perspective from this process, or if it is simply a calibration of the microprocessor for the purpose of providing accurate time estimates.
