The production line under consideration went through a wire section rebuild in the beginning of year 2003. The objective of the rebuild was to improve paper quality and printability. The quality of the base paper and printability of coated paper were greatly improved after the rebuild. Improved formation of the base paper was the key feature having a positive effect on coated paper quality. This could be seen as improved coated paper PPS roughness as well as improved paper gloss. However, paper machine run ability and efficiency decreased somewhat as compared to before the rebuild. The objective for this work was to find optimal running parameter settings for the new wire section, which would maximize paper quality without deteriorati...
