Saddle-stitch binding creates 4 printed pages out of each individual sheet of paper. For 8.5x11 stapled booklets, 2 pages are printed on each side of an 11x17 sheet, creating 4 - 8.5x11 pages out of each. The booklet printer folds the sheets, nests them together and staples them through the fold, or saddle. Because the folding and stapling is done by machine, this keeps the costs low. This makes saddle-stitch printing ideal for material such as product catalogs, magazines, newsletters, student publications, event guides and more.
