One of the papermaker’s greatest challenges entails finding reliable metrics that will assure that the products he makes will perform to customer expectations. When the papermaker finds such metrics, he can use it to reduce product variability and manage costs. The Emveco stylus method (Tappi T575) is a metric that predicts flexographic printability more reliably than traditional air-leak methods. Consequently, papermakers can use the stylus method to reduce variability associated with less predictive metrics, and monitor the effect of paper machine clothing and roll condition on printability.
