Deducing Ink Spreading Curves from Reflection Spectra Acquired Within Printed Color Images

Roger Hersch, Thomas Bugnon, Mathieu Hébert, Mathieu Brichon

The Yule–Nielsen modified spectral Neugebauer model (YNSN) enhanced for accounting for ink spreading in the different ink superposition conditions provides accurate spectral predictions, but requires one to measure the reflectances of special halftone cali ...

Deducing Ink Thickness Variations by a Spectral Prediction Model

Roger Hersch, Safer Mourad, Thomas Bugnon, Peter Amrhyn, Mathieu Brichon, Frédérique Crété

Most existing techniques for regulating the ink flow in offset presses rely oil density measurements carried out oil specially printed patches. In the present contribution. we develop a methodology to deduce ink thickness variations from spectral measureme ...

Simplified Ink Spreading Equations for CMYK Halftone Prints

Roger Hersch, Thomas Bugnon, Mathieu Brichon

The Yule-Nielsen modified spectral Neugebauer model enables predicting reflectance spectra from surface coverages. In order to provide high prediction accuracy, this model is enhanced with an ink spreading model accounting for physical dot gain. Traditiona ...

Model-Based deduction of CMYK Surface Coverages from Visible and Infrared Spectral Measurements of Halftone Prints

Roger Hersch, Thomas Bugnon, Mathieu Brichon

The Yule-Nielsen modified Spectral Neugebauer reflection prediction model enhanced with an ink spreading model provides high accuracy when predicting reflectance spectra from ink surface coverages. In the present contribution, we try to inverse the model, ...
