Surface chemistry: The phenomena wetting, spreading and adhesion of the paint is explained. The doctoral student learns to combine surface chemical models with contact angle measurements to select appropriate combinations of inks and substrates. (2h)
Advanced characterization methods: Advanced measurement methods and techniques are described. The doctoral student learns to select and apply methods for determining surface composition and location of components such as printing ink or latex within the coating layer. (3h)
Paper Optics: Basic paper optics and the concept of colour are explained. The doctoral student learns to explain and to apply concepts such as light scattering, brightness, opacity and colour. (2h)
Pore structure and absorption: The doctoral student learn how pore structure is characterized and how different pigments affect the pore structure. Absorption of ink in the coating layer is explained using advanced mathematical models. The doctoral student will learn to explain how absorption of different inks through different structures. (4h)
Surface topography and contact mechanics: The concept of topography is addressed by definitions of surface roughness. Methods for measuring topography at different size levels are reviewed as well as the principles for how the measurements are performed. The influence of topography on contact area and print quality is addressed. The doctoral student should be able to choose the relevant method for characterizing surface or paper topography to ensure print quality for the most common printing methods. (2h)
Mechanical properties and converting: The material chemistry of the coating layer is treated as well as the most common converting methods. The doctoral student will learn how coating layer components affect the mechanical properties and how different converting operations affect the stress and strain field near the surface of the paper or cardboard. (3h)
Pressure quality: Print quality and perception are dealt with. The doctoral student should be able to identify different printing defects and describe how we experience them, and propose appropriate measurement methods to quantify them. (2h)
Printing methods: Offset printing, ink jet printing, flexography and electronics printing are dealt with. The doctoral student will learn how to apply the knowledge from the course by describing how the composition of the coating layer and the application process affect the absorption of ink and print quality for the various processes. (8h)
In addition to the lectures, the doctoral student is expected to engage in self-study where they delve into and reflect on the content of the lecture to an extent of at least 3 hours per lecture hour to build up an understanding of how to apply the knowledge gained during the course. This can be by theoretical studies or practical trials while performing research. If necessary, students are expected to find relevant literature within the subject. The examination is expected to take between 4 and 6 hours.
