Research topics

The FunPrint group develops research from the inks formulation to the printed materials, in a large field of...
  • Applications ranging from traditional printing to printed electronics.
  • Printed substrates: lignocellulosic materials, polymers, non-wovens, glass, ceramics, silicon...
  • Printing processes: inkjet, flexography, rotogravure, screen printing, offset and electrophotography.
The scope of this group is relatively multidisciplinary and integrates all stages of the graphic chain, from design (pattern shape of printing in prepress) to printing. This requires a thorough knowledge of materials used, the online setting and process monitoring and the control of the final quality of the printed product. In this context, the study of printed substrates (structures, physical properties) is an essential element for their implementation in the printing processes. Inks and toners and other functional fluids knowledge, their composition and their rheological and physicochemical behavior is also conclusive. Their formulation is complex because it must allow good compatibility with the print media, the adapatation to the process referred and the final product functionality by integrating its usage constraints. The analysis of the fluid / support interactions is essential for the control of the ink transfer and requires the study of surfaces and interfaces (physical chemistry, topography ...). In some cases (offset, flexography, rotogravure), the ink transfer is not direct and the substrate receives ink through a specific printer for the process. The development of this element, essential in the final reproduction finesse, requires knowledge both in use, interface and automation of specific softwares (digital stream...) and in chemistry and physical chemistry of materials.

The main research works of the FunPrint group focuses on the development and optimization of printing processes of various media for new applications. In the field of energy, studies are conducted on printing components for fuel cells, photovoltaic cells and lithium-ion batteries. In the field of printed electronics, the work involves the development of conductive tracks by printing processes for communicating objects (RFID, for example). The grhas a large park of printing pilots presses and laboratories as well as characterization equipments dedicated to its activity (rotational rheometer, surface tension measurement and surface energy, 3D topography, spectrophotometer, measure of electrical conductivity 4 points, battery tester ...).
