It is becoming increasingly important to the paper industry to be able to produce paper with high brightness and opacity. Good formation is also highly important. For these reasons, the industry is investigating the way the fines, fiber, and filler are distributed using the different types of paper machines.

Through this thesis work, it will be investigated how the filler distribution affects the optical properties of a sheet and what filler distribution will give maximum scattering power, brightness and opacity. From this it may be possible to suggest what paper machine variables will give filler distributions with improved optical properties.
