Duplo's DSS-350 Square Spine is an optional unit which can be used with most Duplo bookletmakers. It offers designers the ability to customize their product by creating a square spine on their booklets, which creates a flatter look. It is capable of producing up to 2,600 booklets per hour.

The DSS-350 Square Spine module adds a square spine finish to offset and digitally-printed booklets, providing a flatter look. With a processing speed of up to 2,600 booklets per hour, the DSS-350 is ideal for low to mid-volume runs and is the fastest of its kind. It can be used as a stand-alone unit or can be configured in-line with the DBM-350 Bookletmaker or in off-line mode with the DBMS Saddle Stitcher to finish a variety of applications including yearbooks, catalogs, calendars, and more.
