This project is one of three sub-projects in an integrated plan for promoting the
technology of high density data storage with use of existing color inkjet printing. It purposes
to study within a period of two years the influence of the color matching coefficients on the
spectral reflectance and transmittance of colors on a substrate. Further, an inverse radiation
analysis will be performed for the estimation of color matching coefficients from reflectance
and transmittance measured by spectrometer. In the project, the extinction/absorption
coefficients of dyes and pigments used as the chromatic colors will be measured with Beer’s
law under appropriate conditions of operational parameters. The expressions for reflectance
and transmittance will be derived from radiation transfer equation for various color matching
coefficients. With the expressions and also use of least squares method, an estimation
method for measuring the color matching values will be presented. During the phase of first
year, the nonscattering dye will be considered. We shall investigate in detail the effect of
various parameters of dyes on radiation properties of a system with colors on a substrate of
various materials. The sensitivity coefficient will be analyzed in order to seek for an optimal
design of the inverse estimation technique. And the technique shall apply for cases with
various color matching values to verify the accuracy. During the second-year project, a
similar analysis as in first year will be performed and color pigments will be investigated,
which is scattering medium. The scattering phenomenon will be included and its effect on
reflectance and transmittance be analyzed to find the optimal situation for estimation of
color matching coefficients.
