- Surface chemistry of paper Surface chemistry of paper
- Surface topography
- Pore structure
- Surface characterization techniques
- Light scattering and paper gloss – Effect of surface properties
- Wettability, capillarity, spreading, special focus on short term wetting
- Mechanical properties (incl. fracture mechanics) of coating layers
- Ink–substrate interaction
After the course, the participants should be able to
- apply a wide range of techniques used to characterize paper surface structure, paper surface chemistry and print quality, and account for the validity of the results of the same characterisation techniques
- explain interfacial phenomena like wetting, absorption, friction and adhesion
- describe the relation between surface topography and paper optical properties, and
- describe how paper surface properties affect ink-paper interaction and print quality in different printing technologies.
- describe the surface cracking phenomena on the basis of converting processes, substrate properties and coating layer composition.
