The replacement of a twenty-year-old quality control system (QCS) on an off-machine coater has solved a mill’s servicing problems and improved the coating application control performance considerably, meeting the customer’s performance guarantees and providing an expected return on investment. New, variable-speed adaptive scanning features have reduced startup waste considerably and have improved the CD profiles. The online diagnostic tools of the new system are valuable operator aids that are used to detect and correct quality variation problems and coating flaws. The fixed point trending feature of the system is used regularly. The system’s high-resolution measurement capabilities have been used by the operators to detect and solve coating streaks on the jet coating stations.
