Influence of Size of Integrated Measured Surface in Colour Match Calculation by Means of Kubelka - Munk Prediction model

The Kubelka– Munk colour model describes the reflectance of coloured sample as a function of absorption spectrum K(λ ), a scattering spectrum S(λ )and the reflectance spectrum of the substrate. When there is a variation in measurement of samples dyed with different shaded dyestuff in corresponding concentrations, certain differences and errors will occur in K/S values and the reliability of K-M operations will become a question. In this paper the aim was to analyse the influence and the importance of size of measured surface through the performance of K– M colour match calculation on yellow and blue dyed samples. While analysing the influence of measured surface size, the importance of lightness parameter in correlation to concentration of dyestuff and hue parameter is accented.
