A paper presented at the IEI Enamellers Congress in May 2005 explains how computer science can contribute to accelerating the world of colour matching, and presents two different models. The first one uses a preliminary studied mixture plan, which enables, by using simple mathematical laws, approaching the searched result on condition that it is possible to realise this result starting from this preliminary set mixture plan. The second model examines the pigment characterisation, which in this way creates a database used by calculation software that recomposes the required colour. This system in comparison to the previous, has no other limit than the art limit. These two systems were initially used in other industries, such as plastics; paintings; inks etc., and have been adapted to the enamel industry.
