Straight collation means the tab order is arranged to work with a specific production flow, so the numbered tabs appear in the correct sequence after insertion or copying. That matters when producing multiple binders, legal sets, or reference packets where one wrong tab order can throw off the whole document. Before ordering, confirm whether your workflow needs straight collated or reverse collated tabs. Also confirm the tab range, sheet size, and side-tab position. For example, 1–25, 26–50, and other ranges are not interchangeable if the binder needs one continuous sequence. If you need different tab styles, compare pre-printed index tabs before ordering.
