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.
