The human eye is capable of differentiating several million colours, despite this subjective visual evaluation, when used for quality control purposes, is no longer preferred as it suffers from a lack of real quantifiable data and inconsistent documentation.
Since the early 1930’s many scientific measuring techniques have been developed by National Standards Organisations, among them the CIE (International Committee of Light), based on a logical numeric scaling where physical parameters and calculations have been clearly defined, universally accepted and adopted. As a result, many methods are today perfectly proven, and governed by major standards such as ASTM, BS, DIN, or ISO etc.
The appearance of effect finishes are influenced by different viewing angles and conditions. Apart from the light-dark flop and colour shift special sparkling effects can be created. Byk-mac is unique as it measures both multi-angle colour and flake characterization in one portable device.
These are available in 4 versions to accommodate both large and small components. The portable version is ideal for customer presentations or for on-site discussions where such facilities would not normally be available.
These standards are designed are intended for colour checking individual measuring instruments, comparison between instruments and other laboratories.
Colour charts offer a quick easy method of comparing samples against known standards, additional benefits can be obtained when used under standard lighting conditions of a light cabinet.
This new portable Spectrophotometer combines the latest and most advanced technology in micro-electronics and colorimetry
