TECNAU: Empower your new high-speed color inkjet printing system with an efficient cutting/stacking solution. Featuring the double-cutting Cutter c52 or single-cutting Cutter c51, Tecnau’s Stack 5251 and Stack 5151 reliably operate as fast as 590 fpm/180 mpm as enabled by the emerging generation of high-speed inkjet printers. Cutting and stacking high-resolution print at these speeds requires a stable web of paper with minimal touchpoints. The taut-web Stack 5251 & 5151 never let go of the web, keeping control for reliable production. The Stacker s51 module produces 1-up, 2-up, 2-up merged or 3-up stacks, utilizing a transport technology which matches well to transactional and simple book applications. North/south job oﬀsetting ensures high-speed operation even for consecutive small set/book-block jobs. Stack 5251 & 5151 feature next generation controls for compatibility with the “Internet of Things” (IoT). The system includes natural-language error reporting on the user screen and onboard diagnostics to help keep the system up and running. IoT options are available for remote monitoring and diagnostics, automatic software updates and preventive maintenance aids.
