Processing factors affecting roughness, optical and mechanical properties of nanocellulose films for optoelectronics

This work aims to understand how nanocellulose (NC) processing can modify the key characteristics of NC films to align with the main requirements for high-performance optoelectronics. The performance of these devices relies heavily on the light transmittan ...

Spectral Neugebauer-based color halftone prediction model accounting for paper fluorescence

Roger Hersch

We present a spectral model for predicting the fluorescent emission and the total reflectance of color halftones printed on optically brightened paper. By relying on extended Neugebauer models, the proposed model accounts for the attenuation by the ink hal ...

Optical Society of America2014

We propose a full reproduction workflow for printing color images on metallic substrates. It relies on an ink spreading enhanced cellular Yule-Nielsen modified spectral Neugebauer model, calibrated with 35 color samples printed on the metal film and measur ...

This paper furnishes the theoretical basis to perform the calibration of one or more ultra-high-precision industrial robots operating in the same workspace. We propose a new calibration procedure that keeps in account the factors that lower the robot accur ...

IEEE2011

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 ...

Transmission Illuminance Proxy HDR Imaging: A New Technique to Quantify Luminous Flux

Marilyne Andersen

A technique to measure arbitrarily complex luminous fluxes across large areas is presented. The technique is founded on high-dynamic range (HDR) imaging technology and can be achieved using a standard consumer digital camera and everyday materials such as ...

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, ...

Application of Data Reconciliation to the Simulation of System Closure Options in a Paper Deinking Process

François Maréchal, Georges Heyen, David Brown

An equation solver data reconciliation software has been used to build a validated model of a waste paper deinking plant, by combining control rooms measurements and design specifications. An optimal sensor system configuration that allows validating key p ...
