standardized lightning

A standardized lightning is called a defined light condition under which the viewer can view and assess prints or objects uniformly. The most important standard illuminants D50 are in accordance with ISO 3664:2009 for printmaker and for color matching in prepress and press (color temperature: 5,000 kelvin) and D65 (color temperature: 6500 K) for internet graphic designer. D65 is the default setting for most monitors.

Other important types of light are TL84, the standard neon light (color temperature: 4,100 kelvin), which dominates factories and supermarkets, and A – incandescent light (light bulb) with a color temperature of 2,700 Kelvin.
