Universal Sheet Finishing

Universal sheet processing system – DocuTrim DT1

In the high-performance range, printing systems only reach their full potential with efficient finishing systems. The Hunkeler DocuTrim is a multifunctional system for online sheet processing that satisfies the requirements of the latest generation of printers. It produces online on sheet-fed printing systems and also works offline. In the online mode, the DocuTrim and printer can also be used separately from one another for processing separate jobs. With its individually combinable cutting, perforating and creasing in the dynamic multi-processor (DMP), the system already addresses the market requirements of tomorrow. It enables the cutting of various formats and position-independent slit cuts and chip-outs. Thanks to the system‘s modular structure, the wide range of solutions can be individually extended.

Dynamic perforation

Dynamic perforation can be carried out with horizontal and vertical lines. With a minimum separation of 40 mm, several lines can be freely positioned on the entire arc. The patterns can be static or can be dynamically triggered by a data matrix code.

Dynamic Perforation


Printed sheets can be cut into a number of smaller sheets, collated and placed in groups as an offset stack. With bleed-off applications, the net format is achieved with a cut-out. Users have the option of integrating a cross-cutter, which enables further cutting patterns.
