Application of Gradation Trajectories to a Yule–Nielsen Spectral Neugebauer Model
Authors: ,
Abstract: The classic Yule–Nielsen spectral Neugebauer model (YNSN), as well as, its further modification the cellular Yule-Nielsen modified spectral Neugebauer model (CYNSN) are widely used to predict the spectral response of different printers especially when printing multispectral images. The models are engaged to define printer control values that produce appropriate spectral reflectances on a given medium. The Yule-Nielsen factor in the models empirically modeling the optical dot gain is obtained by different regression-based approaches and has no general definition algorithm. This is a kind of disadvantage. In the work, we compare the results of the modified CYNSN and the YNSN with approach of gradation trajectories (YNSNGT). The gradation trajectories are such a way of characterizing the printer, in which each tone value in the original layout is assigned a certain effective tone value so that the linear increment of the tone in the layout corresponds to a linear color increment on the print in the sense of dE00. We have demonstrated that our YNSNGT approach provides comparable prediction accuracy with incomparably faster calculations.
