In the Focus Session on “Excellence in Printing,” Frank Huls, Director of Knowledge and Testing (a company), speaks about the necessity of materials testing to reach a good and constant quality level in printing while at the same time reducing costs. Since it is difficult for a printing plant to compare materials or do its own testing, there is an urgent need for information and knowledge in this area, Huls says. His company develops testing methods and offers on-site testing in cooperation with the printer.
