Abstract

In Kubelka-Munk theory, there is a fairly linear relationship between (K/S) vs. concentration. To access this space, it is necessary to have reflectance data which obtain of expensive devices such as spectrophotometer or it is acceptable from spectral characterization of modern equipments like camera and scanner. The spectral characterization needs the spectral sensitivity of the device that is difficult and time consuming job to measure. The present work uses colorimetric characterization of a scanner and Cohen and Kappauf theory (Matrix R) to calculate fundamental stimulus space. The results showed the estimated fundamental stimulus space (N*) is not scalable and it can transfer to a more desirable scalable space, i.e. (K/S)* using non-linear transfer based Kubelka-Munk theory. With select extended regions of wavelengths, a desirable space was provided to have a suitable communication to study the behavior of dyes on textiles by using simple and inexpensive equipments at the specific lighting and viewing conditions.
