Standardized light

A standardized light 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 colour matching in prepress and press (colour temperature: 5,000 kelvin) and D65 (colour 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 (colour temperature: 4,100 kelvin), which dominates factories and supermarkets, and A – incandescent light (light bulb) with a colour temperature of 2,700 Kelvin.

TL 84

Light of the neon fluorescent type F11 or TL84 is the classic neon light, the typical “department store lighting”. TL84 represents a three-band fluorescent lamp with 4000 Kelvin. This light is installed in many standard light boxes, to compare the reproduction of materials or surfaces with D50 or D65 standard light.
