Influence of paper structure on printability: Characterisation of paper using X-Ray Synchrotron Microtomography
The focus is set on wood fibre-based materials and the characterisation of such fibrous structures at microscopic level. An important aim of this research is to establish a relationship between the structure of papers and their physical properties. Characterisation of fibrous structures of wood fibre-based products is obviously a key factor for the development of the printing industry and also for the improvement of the final product. Therefore in order to optimise the printability, it is necessary to measure and to characterise the resulting structure at the fibrous level. For the wood fibre-based products, the characteristic size has an order of magnitude of few microns. First, some measurements were carried out in order to characterise the topography of the papers. In a second part, some complementary measurements were carried out on the considered samples, using synchrotron source based X-Ray microtomography tools to describe the structure. Consequently, a 3D description of the fine fibrous structure is obtained from X-Ray microtomography. The experimental set-up will be briefly presented. We have carried out experiments at the European Synchrotron Radiation Facility (ESRF) located at Grenoble. The presented examples will illustrate the potential of this technique to describe such structures and therefore optimise the final product.

For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
