Abstract

Some problems in process of dark achromatic hues reproduction and matching in graphic industry, where requests on colour matching are very high, are discussed. When achromatic hues is concerned, in terms of high requests on colour parameter matching, right on time production, quick response and high quality standards requests, the production and moreover the reproduction is subject to many variables and represent the manufacturing process of high complexity. The aim is to achieve a graphic reproduction with defined colour parameters and remission characteristics as close as possible to a standard. In this paper, black and grey hues characterized with average lightness value L*≤ 20, were analysed. Subjective as well as objective colour evaluation have been performed and results of colour differences obtained by two colour difference formulae, CIELAB and CMC(l:c) have been compared.
