D50
D50 is the standard lighting condition of the printing industry. It has a degree of whiteness of 5,000 Kelvin, which is the colour that glowing metal at 5,000 Kelvin would cast.

D65
D65 is standardized viewing condition with 6500 K color temperature. It is the default setting for most monitors and is mainly used in color matching etc. for websites, so in media that are considered primarily to be viewed on the monitor.
In the printing industry, the standard light is D50 according to ISO 3664: 2009 standard, a warmer light than D65 with 5000 Kelvin color temperature, which is also used for color matching on the press and in the evaluation of proofs.
GTI
The GTI GmbH is beside Just Normlicht a renowned manufacturer of standard light tubes and standardized light consoles and colour cabins.
Just
The Just Normlicht GmbH is the most famous manufacturer of standard lighting solutions in the printing sector. The company Just from the Swabian Weilheim / Teck sells alongside the classic D50 and D65 standard light tubes and various proof lights, stations and light booths, where prints can be checked under standardized lighting.
Kelvin
Kelvin is an absolute temperature unit, which is used in science.
The color temperature is in Kelvin of a light source, a monitor or an image corresponds to the temperature of a perfectly black object, that would glow at this temperature.
Standardized light
Standardized lighting refers to defined lighting conditions under which viewers can uniformly view and evaluate prints or objects. The most important standardized lighting type is D50 for printmakers (colour temperature: 5,000 Kelvin).
