Assessment of the colorimetric behaviour of different spectrophotometers

Abstract

Colour reproduction is based on the ability to communicate colour information accurately. The different instrument manufacturers, models and conditions result in difficult colour communication due to the loose or inexistent inter-instrumental agreement between them. With this study we have tried to develop an application to correct colour instruments by software by applying multidimensional polynomial transformations between pairs of instruments. This application will filter one spectrophotometer measurement, and apply a correcting factor to emulate the colorimetric response of any other spectrophotometer.
