How black is black really?
Black has been and still is one of the most popular colors. In the development of black colors, the depth is objectively evaluated with the Jetness index based on colorimetric data. spectro2guide Pro was enhanced to measure deepest blacks with highest accuracy.
0-20 GU: ± 0,1 GU
20-100 GU: ± 0,2 GU
0-20 GU: ± 0,5 GU
20-100 GU: ± 1,0 GU
The basic building blocks of color measurement
Visual color perception is influenced by our individual color preferences, which are dependent on personal factors (mood, age, gender etc.), environment (lighting, surrounding etc.) as well as our ability to communicate color and color differences. A color looks different in the department store (cool white fluorescent lighting) than at home (warm, incandescent lighting). In order to guarantee consistent color and appearance under all possible circumstances, it is essential to standardize light source, observer and understand the spectral remission data of the object. This information will be the basis for calculation of colorimetric data as it is used for color communication and color QC in production.Read more
Color measurement of BLACK
Already in the Stone Age, black based on charcoal was used as one of the first colors ever. The measurement and qualification of black has been a challenge since then, as it reflects hardly any light. On the one hand, special indices are needed because evaluation using L*a*b* values is only suitable to a very limited extent. On the other hand, the selection of appropriate measuring instruments with outstanding technical performance also plays an essential role. The following technical article describes how to raise quality control of deep and deepest black colors to a new level of precision and reliability.Read more
