M. Abed Department of Color Physics, Institute for Color Science and Technology S.H. Amirshahi Textile Engineering Department, Amirkabir University of Technology S. M. Mortazavi Textile Engineering Department, Isfahan University of Technology Journal Article 1970 01 01 In this study, the characterization of a four-color halftone printer was carried out by original Neugebauer and n-modified 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 modified Neugebuer method is led to better outcome.
