Characterisation of paper surfaces for improved printing paper grades

Paper is the most important material for the dissemination of information. It has low cost and is environmentally friendly. For the reproduction of letters and pictures, the paper surface is the critical part. As the paper is composed of fibres, fines and mineral fillers, the surface, as well as the structural characteristics of these components determine the properties of the paper surface.

 

The surface chemistry of paper is influenced by raw materials and additives used in the papermaking processes. The paper surface structure is also influenced by the papermaking unit operations such as forming, pressing, drying, calendering and coating.

 

The final quality of printed images depends on the uniformity of the paper surface topography and chemistry, as well as the printing conditions.

 

The main objective of the Action is to develop and improve methods for analysis of printing paper surfaces in order to improve print quality.
