Lecture

Physics and Technology of Printing: Part I

Description

This lecture covers the physics and technology behind printing processes, focusing on the advantages of printing systems without lithography or vacuum processing. It discusses the cost advantages, added functionalities, and integration possibilities of printing techniques, as well as the trade-offs in resolution, speed, and viscosity. Various printing methods such as gravure, screen, flexographic, offset, continuous inkjet, thermal inkjet, aerosol jet, and piezo inkjet printing are explained in detail. The lecture also delves into the importance of choosing the right printing technique based on material properties, physical requirements, and economic factors. Additionally, it explores fluid properties, fluid flow through pipes, the Reynolds number, ink design considerations, drop formation mechanisms, and ink formulation criteria.
