Defining Optimum Photomechanical Color Reproduction

Whilst a large proportion of color reproduction is very pleasing there is no objective measure of what constitutes a good reproduction. In general, a colorimetric match does not prove satisfactory and the principal reasons for this are well known. What is required is a model which defines Color Appearance. Recently, two comprehensive models have been proposed by Hunt (1987) and Nayatani (1987). These are in process of being evaluated for our application and this paper will provide a status report of this work and discuss how well it applies to Graphic Arts.
