Compatible with the MBM Sprint booklet making systems, including the Sprint 3000 and the Sprint 5000, this trimming system creates a clean edge on your finished booklets. When you fold pages together into a booklet, especially those with many sheets, you will notice that the edges of the open end are not aligned properly because of the naturally occurring imperfect registration caused by the fold. This face trimming system will clean up those edges for a perfectly straight and clean finished booklet. Because it works in-line with the Sprint systems, there is no manual inserting or paper handling required. Instead, the booklet will go straight from your Sprint machine into the trimmer, quickly and easily producing your finished piece onto the exit convener. If you own the Sprint 3000 or Sprint 5000 booklet makers, but want to produce a more perfectly square booklet, then buy the MBM face trimmer online to add to your system.
