Fully automated job changeovers for full-bleed applications
Revolution 50 AutoSetup reads a 2D Datamatrix to support changes in imposition (among 1-up, 2-up, 3-up and 4-up) and sheet lengths with no touchpoints. Automated features enhance productivity, minimize setup times and reduce labor, making the system particularly well-suited for commercial and direct mail printers.
Users transition effortlessly across various applications. The required operator skill level is significantly reduced compared to non-automated finishing lines, making the system a good match for organizations facing challenges finding skilled labor. The system also includes standard Tecnau Revolution 50 cutline features, such as a slide-out knife assembly, decurler, and dynamic web aligner, with available Tecnau Connect IoT platform. These Revolution 50 features and options further reduce application challenges and labor requirements while increasing press uptime.
