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 monochrome reflectance spectra with an extended Kubelka-Munk model

Roger Hersch, Patrick Emmel, Safer Mourad

We present a prediction model for digital printers and more specifically for electrophotographic devices. On the one hand, we propose an electrophotographic simulation model which estimates the microscopic structure of any printed toner layer based on its ...

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 ...

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 ...

MEMS infrared gas spectrometer based on a porous silicon tunable filter

Philippe Renaud, Sandra Schweizer, Gerhard Lammel

We present a MEMS infrared spectrometer for selective and quantitative chemical gas analysis. infrared absorption spectroscopy can distinguish gases easily and also detect nonreactive molecules like CO2, in contrast to e.g. metal oxide gas sensors The foll ...

Microspectrometer based on a tunable optical filter of porous silicon

Philippe Renaud, Sandra Schweizer, Gerhard Lammel

We present a tunable interference filter for infrared and visible light that scans the desired part of the optical spectrum within milliseconds. A single pixel detector measures serially the intensity at selected wavelengths. This concept avoids expensive ...

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 ...
