Ink-Jetting of Polymers and Biomaterials

Jürgen Brugger, Vahid Fakhfouri, Kristopher Pataky, Yun Luo

Inkjet printing is a very common and largely developed technology in desktop printers. A wide range of diverse technologies, with different principles of drop generation, fall into the inkjet printing category. Inkjet technology, particularly the drop-on-d ...

A domain decomposition method for advection-diffusion processes with application to blood solutes

Alfio Quarteroni, Paolo Zunino

We consider a heterogeneous model for the dynamics of a blood solute both in the vascular lumen and inside the arterial wall. In the lumen, we consider an advection-diffusion equation, where the convective field is provided by the velocity of blood, which ...

Modeling ink spreading for color prediction

Roger Hersch, Patrick Emmel

This study aims at modeling ink spreading in order to improve the prediction of the reflection spectra of three ink color prints. Ink spreading is a kind of dot gain which causes significant color deviations in ink jet printing. We have developed an ink sp ...

Prediction of the Reflection Spectra of Three Ink Colour Prints

Roger Hersch, Patrick Emmel

We have developed a colour prediction model and an ink-spreading model. The present study aims at confirming the validity of both models for the case of ink-jet prints using cyan, magenta and yellow inks. Our colour prediction model, augmented by the ink-j ...

Predicting transmittance spectra of electrophotographic color prints

Roger Hersch, Patrick Emmel, Safer Mourad

For dry toner electrophotographic color printers, we present a numerical simulation model describing the color printer response based on a physical characterization of the different electrophotographic process steps. The proposed model introduces a Cross T ...

Predicting Monochrome Color Transmittance Spectra of Electrophotographic Prints

Roger Hersch, Patrick Emmel, Safer Mourad

We create a computer based numerical model to predict the color spectra of printed patches on dry toner electrophotographic printers. The goal of this research is to obtain a simplified model describing the input-output behavior of the printers based on th ...

Exploring ink spreading

Roger Hersch, Patrick Emmel

This study aims at exploring ink spreading, which causes significant colour deviations in ink-jet printing. We present a method for investigating this phenomenon by considering only a limited number of cases. Using a combinatorial approach based on Polya's ...

A Unified model for color prediction of halftoned prints

Roger Hersch, Patrick Emmel

This study introduces a new model and a new mathematical formulation describing the light scattering and ink spreading phenomena in printing. The new model generalizes the classical Kubelka-Munk theory, and unifies it with the Neugebauer model within a sin ...

Structure artifact free multi-level error diffusion algorithm

Roger Hersch

Error-diffusion is widely used to generate intensity levels between the primary levels of multi-level colour printing devices (ink-jet printers, electrophotographic printers). Standard error-diffusion algorithms produce structure artifacts at rational inte ...

Modèles de prédiction couleur appliqués à l'impression jet d'encre

Patrick Emmel

In order to guarantee good colour reproduction, modern printers use very large calibration tables based on the measurement of large sample sets. In this thesis, we aim at establishing an accurate colour prediction model which is able to compute the spectra ...
