Prevents toner cracking on digitally-printed documents
Processes up to 20 creases in a single pass
Optional slitting and perforating modules


Prevent toner cracking and unattractive fold lines on documents with the Duplo DC-446 Paper Creaser. A simple and affordable finishing solution no digital printer should do without, the DC-446 creases a wide range of applications at up to 50 sheets per minute. Creasing digitally-printed output prior to folding ensures a clean, professional finish and makes it easier for folding devices to bend with accuracy. The DC-446 applies up to 15 creases in a single pass with great precision and is perfect for creating unique accordion applications and other color documents that require a fold right along the color break. Fully automatic and easy to use, the DC-446 is ideal for finishing short-run offset and digital applications including greeting cards, postcards, brochures, book covers, and more! 

A number of optional features are also available to maximize its functionality. An air-knife provides additional air to improve feed consistency and reduce static problems while double-feed detectors stop the machine when two or more sheets are fed, thus preventing mis-feeds and paper jams. Additionally, slitting and perforating modules can be added to eliminate white borders and create perforated pieces. Up to three slitting and perforating modules can be installed for increased versatility.

The DC-446 can also be configured with an in-line knife folder, enabling users to crease and fold pieces in a single pass. Please refer to the Integrated Folding System page for more information.
