Comparison of Neugebauer and n-Modified Neugebauer Models for the Characterization of a Four-color Halftone Printer

In this study, the characterization of a four-color halftone printer was carried out by original Neugebauer and nmodified Neugebauer models. According to the results, the modified Neugebauer method was led to a better outcome. Although the relation between target dot area and real dot area for a color inks were linear, the nonlinearity of target and real dot area for black ink caused some error especially in dark samples. In the n-modified Neugebauer model the nonlinearity between real and target dot area was considered. Therefore, this model was led to a better color reproduction accuracy as comparison with the original Neugebauer model. The results showed that the modifiedNeugebuer method is led to better outcome.
