True

The region of the electromagnetic spectrum between 380 and 720 nanometers.

Viewing Spectrum

Known spectral data established by the CIE for difference types of light sources.

CIE standard illuminants 

A hypothetical observer having the tristimulus color-mixture data recommended in 1931 by the CIE for a 2° viewing angle. A supplementary observer for a larger angle of 10° was adopted in 1964.

CIE standard observer

A measurement of the color of light radiated by an object while it is being heated. This measurement is expressed in terms of degrees Kelvin.

Color Temperature

The CIE Standard Illuminant that represents a color temperature of 5000°K. This is the color temperature that is most widely used in graphic arts industry viewing booths.

D50

The CIE Standard Illuminant that represents a color temperature of 6500° K.

D65

The phenomenon where two colors appear to match under on one light source, yet do not match under a different light source.

Metamerism

Matching colors between an original image, scanner, monitor, color printer and final press sheet.

Color Management

Adjustment of images to bring them into a state of visual optimization
