As part of a long-term strategy to redefine the role of testing in the mill, while also increasing testing frequency for improved operations and process stability, SCA Graphic Sundsvall has for many years been using Metso Automation's PaperLab and PulpExpert automated testing units at its 850,000-tonne/yr Ortviken lightweight coated (LWC) and newsprint paper mill in Sundsvall, Sweden. In 1992, Ortviken was confident in the ability of PaperLab to handle the testing and therefore decided to reduce the staffing to three testers per shift. The success with these initiatives got Ortviken thinking about a more radical step, which would be to eliminate all shift testers. The benefits that Ortviken has seen with automated testing, including higher frequency of tests, better repeatability, less manual labor, faster feedback time to the operators and improved process stability, all make it hard to see the mill ever going back to the traditional system of paper and pulp quality testing.
