Saddle Stitchers — A Stitch In Time

One widely adopted solution to this challenge is to impose the job multiple-up in four-page flat signatures, then run it on a small-format press (33˝ or smaller). The sheets are cut to flat-sheet, four-page signatures that are loaded into a high-speed vacuum collator equipped with in-line stitching, folding and face-trimming accessories (see accompanying photo on page 74).
