Abstract

A spectral-based Neugebauer model, which is a direct derivation of the Neugebauer equations, is proposed for the prediction of printed color. A distinctive feature of this model is that the dot area ratios are modified differently at every wavelength. The capacity of this Neugebauer model to work for all binary color printing is doubtful however, due to the fact that it appears to have been examined prior to the development of some of the more complex models that have been proposed for accurate prediction. This research investigates the conditions under which the model can be applied and its effectiveness. Three experiments were conducted. The first experiment evaluated which kind of printers the model works on. The model achieved satisfactory prediction accuracy for application in sheet and web offset. The second experiment investigated how the screening conditions of offset printing affect the model performance. AM, FM, and AM⁄FM hybrid screenings were evaluated. The model only worked sufficiently under the AM screening condition. The purpose of the final experiment was to evaluate the accuracy of the model's prediction of printed color on different types of paper using offset printing. The results showed that the model performed sufficiently on any type of the coated paper. In conclusion, the model proves to be a good predictor of color that is printed on coated paper using offset printing and under AM screening.
