A framework describing influences of ink penetration and Yule-Nielsen effect on the reflectance and tristimulus values of a halftone sample has been proposed. General expressions of the reflectance values and CIEXYZ tristimulus values have been derived. Simulations for images printed with two inks have been carried out by applying Gaussian type of point spread function (PSF). Dependence of Yule-Nielsen effect on the optical properties of substrate, inks, the dot geometry, ink penetration etc., have been discussed.
