| COURSE FOCUS | |
| This course will present the concepts and measurement techniques that are required in order to understand how surface tension, wetting and capillarity affect printing processes. The first goal will be to develop the understanding of surface tension and interfacial tension, which are essential properties of the materials involved in printing systems (eg. ink, plastic substrates, paper). Then, the various modes of wetting and capillary penetration, which are basic processes underlying most printing operations, will be discussed. Intended audience This course is directly relevant to anyone working in the fields of ink jet ink formulation and development, substrate development - such as papers, films, coatings and metal and glass substrates - and the design and development of ink jet printheads. |

| Professor Abraham Marmur Department of Chemical Engineering Technion Israel Institute of Technology Haifa, Israel Professor Abraham Marmur received his PhD in 1974 from the Technion Israel Institute of Technology. Then he spent two years as a post-doc at the State University of New York at Buffalo. Later he was a visiting associate professor at the University of Wisconsin Madison, and a visiting scientist at the IBM Almaden Research Center. Professor Marmur has been working in the field of interfacial phenomena and wetting for over thirty years. He has published many papers on the theory and practice of wetting processes, and has been consulting for major companies involved in the design and utilization of ink jet printing systems. He has also participated in many international conferences and has been active in lecturing on interfacial phenomena in universities and industrial sites in many countries. At Technion, Professor Marmur received awards for excellence in research and in teaching. In addition, Professor Marmur was an editor of Reviews in Chemical Engineering, was on the advisory committee of Journal of Colloid and Interface Science and Journal of Adhesion Science and Technology, and is on the editorial board of Colloids and Surfaces A. |
