Traditionally, Computer Colorant Formulation has been implemented using a theory of radiation transfer known as the Kubelka-Munk (K-M) theory. In recent studies, Artificial Neural Networks (ANNs) has been put forward for dealing with color formulation problems. This paper investigates the ability of Support Vector Machines (SVMs), a particular machine learning technique, to help color adjustmen...

In this work optical properties of titanium dioxide nanoparticles were studied. Titanium dioxide nanoparticles were synthesized by the sol-gel method followed by a hydrothermal treatment using tetraisopropyl orthotitanate (TIOT) and 2-propanol. The synthesized samples were characterized by X-ray diffraction (XRD), UV-Vis diffuse reflectance spectroscopy (UV/DRS) and nitrogen adsorption-desorpti...

The use of multiple substrates in color printers requires color characterization for each of the individual media. A full re-characterization for each substrate is measurement and labor intensive. In this paper, a variety of methods are proposed and evaluated for determining the color characterization for a new substrate based on a complete characterization on a reference substrate and a small ...

We extend the applicability of the recently revised Kubelka-Munk (K-M) theory to inhomogeneous optical media by treating inhomogeneous ink penetration of the substrate. We propose a method for describing light propagation in either homogeneous or inhomogeneous layers using series representations for the K-M scattering and absorption coefficients as well as for intensities of the upward and down...

A common method for characterizing a colored pigment is making a ramp contain several mixtures of the colored and white pigments. Then, by applying the least squares technique using all the samples, absorption and scattering coefficients can be calculated. Making several samples is time consuming. In this approach, the minimum number of samples for characterizing the pigments using single-and t...

The determination of the band gap energy (Eg) semiconductors powder materials can be performed from diffuse reflectance spectroscopy (DRS) measurements. For this purpose, classical theory proposed by Kubelka and Munk (K-M) so-called plot Tauc, both discussed here, have been largely employed. We investigate Eg values anatase TiO2 particles synthesized precipitation titanyl sulphate in presence 5...
