Our largest client has decided to change their monthly catalog from a basic saddle stitched booklet to something more complicated. We currently print these digitally, 2-up pre-collated then trim and hand feed into our Plockmatic booklet maker. Now they are switching to saddle stitched books with multiple tabs dividing the sections. Meaning we can't use our Plock and will have to revert to offline folding, then hand collating and stitching. I am curious if any of the booklet makers allow for books with multiple tabs in them.
