Thanks to the experience acquired in over thirty years of research by its R&D department, SEI Laser has specifically developed a laser machine for Paper Converting and the Graphic Arts industry: PaperOne Line.

The concept behind the project is the digitalisation of the analogue process of paper die-cutting. Thanks to the laser, an innovative cutting, marking, micro-perforating and decorating solution, this system is now a revolutionary device for professionals who wish to achieve excellent production performance.

The automatic loading and unloading, the acquisition of data by barcode reading, the innovative quality of the die cutting and decoration make PaperOne Line a complete system that totally transforms the finishing and converting steps of paper sheet processing.

PaperOne Line has an user-friendly interface, a wide range of configurations and options to ensure a unique customisation.

A masterpiece of technology designed for the people who want to invest in the future.


Up to 2500 sheets/hour and 3 laser configurations available to satisfy any requirement.


Die-cutting, micro-perforation, decoration and creasing by laser of sheets, both front and back, according to the graphics and design.


It can be fully incorporated into the modern digital production process, particularly in the case of Web to Print, Web to Packaging and Web to PaperDesign systems.

PaperOne Line is a state-of-the-art laser technology in the sector of graphic arts.
