Square Bind booklets are several sheets of paper bounded and stapled - using 2 staples to bind the sheets together, like Saddle-Stitch booklets.
The difference comes with the fact that we square out the binding edge for the brochure to resemble a Perfect Bind booklet.
It is a less expensive binding method than a glued booklet and particularly effective in booklets with more than 32-pages (the min 4-page count).
Use Square Bind for booklets, pamphlets, menus, magazines containing more than 32-pages in total.
Go for the Square Bind to have a Perfect Bind look for less!
