Duplo DFS-3500 Full-Bleed Bookletmaking System

Duplo DFS-3500 Full-Bleed Bookletmaking System

Duplo’s near-line DFS-3500 Bookletmaking System has been designed to completely finish full-bleed booklets in a single pass. Combining the creasing and slitting functions of the DC-446 Creaser with the stitching, folding, and trimming capabilities of the mid-range DBM-350/T Bookletmaker and Trimmer, the DFS-3500 delivers an affordable all-in-one bookletmaking system ideal for short-run applications.

By automating the finishing process required to create full-bleed booklets, the DFS-3500 eliminates the need for a separate guillotine cutter and creasing machine. Time consuming set-ups, wasted material, and turnaround times are all reduced. Complete job set-up is done from the user-friendly DC-446 control panel and up to 30 jobs can be saved for quick and easy recall. The DFS-3500 Bookletmaking System’s ability to slit, crease, stitch, fold, and trim in one pass makes it the perfect solution for producing applications such as calendars, catalogs, yearbooks, newsletters, and more.

Superior, High Capacity Feeding
With a 4-inch stack capacity and top feeding air suction technology, the DFS-3500 enables users to run a productive bookletmaking operation. The sheets feed from the top of the stack to reduce scratching commonly caused by bottom feeders and the high capacity feeder means the system can run for a longer period of time without constant reloading. To ensure the accuracy of each booklet, the DFS-3500 uses a double feed detection sensor to stop the machine when it detects two or more sheets have been fed.

In-line Creasing and Slitting
Creasing the cover and innermost sheets prior to folding prevents toner cracking and guarantees crisp, professional folds. The optional slitting module trims the head and foot of each sheet for a full-bleed trim before it accumulates in the bookletmaker. The margins are deposited into a bin located underneath the bridge unit. By slitting in-line, operators are no longer required to pre-cut the sheets on a separate guillotine cutter, resulting in decreased downtime and increased productivity.

Crease-only Mode
The DFS-3500 can also be used as a dedicated creaser by simply switching the position of the bridge unit. At speeds up to 60 sheets per minute, the DC-446 can crease a range of flat applications including greeting cards, brochures, menus, and more. For added versatility, up to three optional slitting and perforating modules can be added for a maximum of 20 creases and 3 perforations per sheet in a single pass.

Variable Data Processing
Using the optional End Mark Reader, the DFS-3500 can produce variable data booklets with different sheet counts for one-toone marketing applications. The End Mark Reader recognizes the mark on the booklet’s cover sheet and automatically begins the stitch, fold, and trim cycle allowing booklets of varying page counts to be processed without any manual adjustments.

True Mid-Level Finish
Utilizing a gentle push belt transport system and heavy duty Deluxe 26D stitcher heads, the DFS-3500 enables operators to produce high quality books efficiently and with minimal training. The system comes equipped with an integrated book spine compressor to improve the lay-flat qualities of the finished book. In addition, operators can add small booklet and side/corner stitching kits to meet varying application requirements. The DBM-350’s ability to handle set-by-set and sheet-by-sheet output make the DFS-3500 Bookletmaking System suitable for printers making the transition from offset to digital.
