2022Functional Ink Formulation for Printing and Coating of Graphene and Other 2D Materials: Challenges and Solutions
Frank Nüesch, Jakob Heier, Sina Abdolhosseinzadeh, Mohammad Jafarpour
The properties of 2D materials are unparalleled when compared to their 3D counterparts; many of these properties are a consequence of their size reduction to only a couple of atomic layers. Metallic, semiconducting, and insulating types can be found and fo ...
WILEY2022Virtual reading of a large ancient handwritten science book
Giorgio Margaritondo, Frédéric Kaplan, Alessandra Patera, Fauzia Albertin, Marco Stampanoni
We present a fundamental development step of a new technique to read and digitize ancient handwritten documents. Chemical analysis by x-ray fluorescence and x-ray tomography enabled us to decipher words and drawings from inside a closed, 200-pages 18th cen ...

Elsevier2016Goniocolorimetry: from measurement to representation in the CIELAB color space
The classical definitions of color are well adapted to diffusing objects, whose color is almost independent of the viewing angle, and to very glossy object observed in the specular direction in respect to the light source. For glossy or iridescent objects, ...
Wiley-Blackwell2011Ink-dependent n-factors for the Yule-Nielsen modified spectral Neugebauer model
Different inks may have different mechanical and/or optical properties. Existing Yule-Nielsen modified Neugebauer spectral prediction models assume however that the inks forming a color halftone behave similarly, i.e. that a single n-factor can model the l ...
Society for Imaging Science and Technology2010Deducing Ink Thickness Variations by a Spectral Prediction Model
Roger Hersch, Thomas Bugnon, Mathieu Brichon, Peter Amrhyn, Safer Mourad, 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 ...
Wiley-Blackwell2009Simplified 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 ...
2008Color images visible under UV light
Roger Hersch, Sylvain Chosson, Philipp Donzé
The present contribution aims at creating color images printed with fluorescent inks that are only visible under UV light. The considered fluorescent inks absorb light in the UV wavelength range and reemit part of it in the visible wavelength range. In con ...
2007Model-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, ...
