WEB & SHEET STUDIES IN COATING/LAMINATING

As Tielkemeier explains, dynamic registration is achieved through the use of a high-speed optical sensor, an encoder, and an eye mark on the printed web. To help temper web tension or velocity fluctuations inherent in an older unit's performance, Tielkemeier suggests a dancer be included in retrofit configurations for a geared press. The optical sensor should be located just before or after the print deck or coating station to provide the final control point reference for registration precision.
