In color reproduction system, 'a role of the Neugebauer equations is a mean to get a set of dot areas for three color or four color reproduction starting from tristimulus value of a target color. To apply the Neugebauer equations, one has to consider each step of system carefully to achieve good color reproduction starting from input device to final printing techniques. The target color has to be described by colorimetric quantities instead of three color densities. Dot areas as unknown in. the simultaneous equations are effective dot areas printed on the papers effected by dot gains during workshop operation including Yule-Nielsen effect. It is necessary to have system analysis on total printing process and physical analysis on each step involved to apply the Neugebauer equations properly.
