Abstract [sv]

This project has been made in cooperation with Stora Enso Research Centre Falun (Research). The background of the project is that Research has customers who demand a method to measure the quantity of varnish online in offset printing. The aim with the project is to investigate if any test method correlates with the quantity of varnish and to improve the understanding of the variables in the varnishing unit. The goal with the project is to develop a functional method. Two printing trials have been performed. The aim with the first trial was to investigate how different factors in the printer influenced the quantity of varnish using reduced factoranalysis. The aim of the second trial was to analyse only a reduced numbers of factors in the varnishing unit. The methods that were used to measure the varnishing quantity are weighing, IR-analysis, gloss, whiteness and brightness. Results from the project show that the weighing method does not work in this study due to basis weight variations of the sheets. The results from weighing did not agree with the results from the other methods. On the other hand there is a strong correation between the IR- and the glossmethods.
