Paper Abstract

A prototype kit containing artefacts, best practice guide and software for enhancing reflectance measurement data are described. The kit uses measurements made on calibrated artefacts to make other reflectance measurement data more reliable, in terms of zero offset and linearity, while also providing traceability to national reflectance scales. The use of the kit can give agreement between measurements made on the same artefact by different instruments of less than the colour discrimination limit of the human eye of 0.5 ΔE*ab colour difference units.
