Polymer structuring by inkjet printing technology / Micro heating arrays with tungsten

The goal of this work is to fabricate polymer structures by using commercial inkjet printing technology. In order to do this, the main questions, which I wanted to answer through the work, are the followings: Is it really possible to deposit polymers by in ...

Spectral prediction and dot surface estimation models for halftone prints

Roger Hersch, Patrick Emmel, Frédérique Crété

We propose a new spectral prediction model as well as new approaches for modeling ink spreading which occurs when printing ink layer superpositions. The spectral prediction model enhances the classical Clapper-Yule model by taking into account the fact tha ...

A Prediction Model for Reflection on Varnished Metallic Plates

Roger Hersch, Mathieu Hébert, Patrick Emmel

Several models predict the reflectance of a rough metallic surface. They are however not adapted to the surfaces used in the packaging industry, such as boxes made of printed metallic plates. For printing purposes, metallic surfaces need to be varnished. L ...

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 ...

Parameterizable fonts based on shape components

Roger Hersch, Changyuan Hu

We propose a new, highly flexible font description method that explicitly describes characters as assemblies of parameterizable shape components. By varying global parameters, we can derive fonts that vary in weight, condensation, and shape. Fonts made of ...

Neugebauer and Demichel: dependence and independence in n-screen superpositions for colour printing

Roger Hersch, Isaac Amidror

The Neugebauer equations and the Demichel equations on which they are based are one of the basic tools for modeling colour printing systems that use the halftoning technique. However, these equations implicitly assume that the colour ink distributions in t ...

Stochastic clustered-dot dithering

Roger Hersch

A new technique for building stochastic clustered-dot screens is being proposed. A large dither matrix comprising thousands of stochastically laid out screen dots is constructed by first laying out the screen dot centers. Screen dot centers are obtained by ...

Reproducing color images using custom inks

We investigate the general problem of reproducing color images on an offset press using custom inks in any combination and number. While this problem has been explored previously for the case of two inks, there are a number of new mathematical and algorith ...

Multi-level colour halftonning algorithms

Roger Hersch, Isaac Amidror, Patrick Emmel

Methods for the halftoning of images on multi-level printing devices such as multi-level ink-jet printers are presented. Due to the relatively large size of single droplets, halftoning algorithms are still needed. However, since halftoning occurs between t ...
