The New Wave of Color Calibration Technology: Cube Calibration


Introduction to Cube Calibration

One of the Awards given out in 2012 by Secrets of Home Theater and High Fidelity for "Technology on the Rise" was for Cube Calibration. For most people this probably doesn't mean much yet, but for those of us that are calibrators, or enthusiasts with an interest in calibration technology, this was a huge development. One might even say that Cube Calibration is the biggest improvement to consumer display technology since the introduction of the Color Management System (CMS).

A traditional CMS calibrates between 5 and 16 points. Usually 2 or 10 grayscale points, and 3 or 6 color points. When designed and implemented correctly, these controls can lead to a very accurate image, with a very color-neutral grayscale and very accurate color primary points. We publish a graphical representation of this, which entails a stck target representing various correct color points; this is known as a CIExy 1931 color diagram, and accompanies all of the display reviews we and many others do. You may also assume that when those measured points match with the reference points on the chart "This display has perfect color", but this is actually a common misconception, and one that Cube Calibration helps to address.

As we review cube calibration technology from Lumagen and SpectraCal, first we have to review how current calibration technology works, and the issues that exist in it.
