Abstract: Optical dot gain is the key point of halftone reconstruction study, and has always
been a meaningful topic of theoretical study. The Yule-Nielsen formula is by far the most widely
used research method of optical dot gain. However, solving the Yule-Nielsen parameter n remains
a difficult problem. This paper disregards solving for the Yule-Nielsen parameter n, analyzes the
light scattering and osmotic effect of halftone presswork, deduces the exact expressions of blank
area of presswork, and determines the reflectivity of the dot part and halftone presswork
according to the point spread function and probability method. Furthermore, this paper analyzes
how the optical dot gain depends on the dot area coverage of presswork, ink layer transmittivity,
and paper-based spectral reflectivity. In addition, a new algorithm model for optical dot gain is
established. By employing the Clapper-Yule Model to calculate the spectral transmittance of
printing ink and comparing it with the practical measured spectral reflectivity of the halftone
presswork proof, the accuracy of the model established in this paper is fully verified. © (2013)
