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, (e.g. ink, plastic substrates, paper, etc.). Then, the various modes of wetting and capillarity penetration, which are the basic processes underlying most printing operations, will be discussed. This course is directly relevant to anyone working in the fields of ink jet in formulation and development, substrate development - such as papers, films, coatings as well as metal, glass or other nonporous substrates - and the development of ink jet printheads.
