Nanostencil and InkJet Printing for Bionanotechnology Applications

Jürgen Brugger, Oscar Vazquez Mena, Kristopher Pataky

In this contribution we describe the application of Ink-Jet printing and Stencil Lithography in bionanotechnology. Both techniques are alternative patterning methods that can be used for the fabrication of biocompatible micro- and nanostructures out of the ...

High-Fidelity Printing Strategies for Printing 3D Vascular Hydrogel Structures

Jürgen Brugger, Philippe Renaud, Matthias Lütolf, Thomas Michael Braschler, Kristopher Pataky

Vascularization arguably poses the most significant hurdle for the success of most biomaterials-based tissue engineering therapies. In this work, we report two printing strategies that permit the 3D Inkjet printing of fluorescent alginate hydro gels into o ...

Deducing 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 ...

Drop-On-Demand Inkjet Printing of SU-8 Polymer

Jürgen Brugger, Alcherio Martinoli, Vahid Fakhfouri, Grégory Mermoud, Joo Yeon Kim

This paper presents drop-on-demand inkjet printing of SU-8 on functionalized surfaces for direct printing of computer controlled polymer patterns. The high viscosity of SU-8 required an in-depth investigation of the print parameters such as pulse amplitude ...

Compensation of printer MTFs

Preliminary experiments have shown that the quality of printed images depends on the capacity of the printing system to accurately reproduce details.1 We propose to improve the quality of printed images by compensating for the Modulation Transfer Function ...

Measurement of printer MTFs

Albrecht Johannes Lindner

In this paper we compare three existing methods to measure the Modulation Transfer Function (MTF) of a printing system. Although all three methods use very distinct approaches, the MTF values computed for two of these methods strongly agree, lending credib ...

Inkjet-Printed Multicolor Arrays of Highly Luminescent Nanocrystal-Based Nanocomposites

Jürgen Brugger, Vahid Fakhfouri, Joo Yeon Kim

Inkjet technology is a compelling method for the flexible and cost-effective printing of functional inks. We show that nanocomposite solutions based on polystyrene and differently sized core/shell-type nanocrystals (NCs) formed by a CdSe core coated with a ...

Evaluation of characterization methods of Printer MTF

Albrecht Johannes Lindner

We explore two recent methods for measuring the Modeling Transfer Function of a printing system. We investigate the dependency on the amplitude when using the sinusoidal patches of the method proposed in and show that for too small amplitudes the measureme ...

Compensating Printer Modulation Transfer Function in Spatial and Color Adaptive Rendering Workflows

Albrecht Johannes Lindner

Experiments have shown that the quality of printed images depends on the capacity of the printing system to accurately re- produce details. We propose to improve the quality by compensat- ing for the Modulation Transfer Function (MTF) of the printing syste ...

Ink thickness variations for the control of color printers

Roger Hersch, Peter Amrhyn

The present invention proposes a method and a computing system for deducing ink thickness variations from spectral reflectance measurements performed on a printing press or on a printer. The computed ink thickness variations enable controlling the ink depo ...
