1. Optics of coated paperboard : Aspects of surface treatment on porous structures
Sammanfattning : Calendering of coated and uncoated paper is widely used to enhance optical properties such as gloss and print quality. The aim of this thesis is to characterize coatings and prints, and to validate models using experimental results from optical measurements of physical samples. Calendering of coated paper often leads to a brightness decrease. LÄS MER

3. Influence of Substrate Topography on Ink Distribution in Flexography
Sammanfattning : The printability of paper in flexography is largely dependent on the topographical characteristics of the substrate. Topography imaging instruments make it possible to obtain three-dimensional scans of paper surfaces that can be further used to calculate valuable quality parameters. LÄS MER
