Abstract

Printing with white ink plays an important role in many printing processes, but white is difficult to integrate into colour management processes since conventional measurements are uncorrelated with the ink amount. A control method for white ink is proposed in which white is printed and measured over black. The resulting colorimetric densities can be modelled by polynomial regression, allowing accurate prediction of tonal value. The model can readily be inverted to predict the colorant amount required to match a given colorimetric density, and hence is a suitable method of measurement that can support process control and colour management.
