So I have a long document (100+ pages). It was originally saddle-stitched (but grew too long). It's set up in facing pages, and now we want to coil-bind it. Do I need to be concerned about inner bleed? I have no idea how that's done, but I hear there are ways to pull the spreads apart and add bleed in the gutter. How necessary is this? I'm in a time-crunch but want to do a good printing job to the extent possible.
Thanks, Phyllis
