<p>An integral overview of the theory needed to design print heads, authored by an expert with over 30 years' experience in the field of inkjet printing.</p> <p>Clearly structured, the book presents the working principle of a print head in a comprehensive and clear form, right from the start. To begin with, the modelling of piezo-driven drop-on-demand print heads is discussed, building on the theory of mechanical vibrations and acoustics. The design of single-nozzle as well as multi-nozzle print heads is presented, including the importance of various parameters that need to be optimized, such as microfluidic dimensions of the flow path, viscosity, surface tension and nozzle shape. Topics such as refilling the nozzle and the impact of the droplet on the surface of the substrate are equally treated.</p> <p>An essential reference for beginning as well as experienced researchers, from ink developers to mechanical engineers, both in industry and academia.</p>
