Abstract

The Neugebauer equation is generally used to predict full color reproduction for printing. Pollak resolved the Neugebauer equation into factors, assuming the additivity of superimposed solid optical densities. Because of differences between predicted and actual results, various modifications of the formula have been suggested. Yule and Nielsen introduced the parameter n. We have now developed a quadratic equation with a factor corresponding the Yule-Nielsen n. By introducing our correction term to Pollak's equation, it is possible to correct approximately for optical dot gain in the case of halftone dots superimposed on paper.
