Wire-O Booklet Printing
Wire-O binding uses a double loop of metal wire threaded through punched holes along the edge of the page. Also called twin loop or double loop binding, it lays completely flat when open and folds all the way back on itself — which is why it's the standard for manuals, workbooks and anything someone needs to keep open while working from it.
WHAT IT'S USED FOR
- Training manuals and instruction guides
- Workbooks, planners and journals
- Technical and reference documents
- Presentation books and proposals
- Calendars and wall-hung pieces
SPECIFICATIONS
- Flat lay: Lays flat at 180° and folds back a full 360°, so the booklet takes up half the desk space when open.
- Page count: Works across a wide range — from thin booklets up to substantial manuals. Pages are added in increments of 2 rather than 4, so odd configurations are possible.
- Binding edge: Long edge is standard. Short edge is available for landscape pieces and flip-style documents.
- Paper: 100lb gloss text is standard. Choose uncoated where people will be writing in the book.
- Durability: The metal wire holds its shape under repeated use better than plastic, which is why it's preferred for documents that live on a workbench or in a training room.
- Note: Pages can be torn out cleanly if needed, and the wire won't distort the way a plastic coil can.
WHY PRINTSTAR
Wire-O binding is hand-finished in our own bindery — it takes more labour than saddle stitch and we don't send it out. Every file is reviewed by a person before printing.
FAQ
What's the difference between wire-o and spiral binding?
Wire-o uses a twin loop of metal wire; spiral uses a single continuous plastic coil. Wire-o looks more formal and holds its shape better under heavy use. Coil is more forgiving — it flexes rather than bends permanently, which suits books that get carried around.
Does wire-o lay completely flat?
Yes, and it folds all the way back on itself so only one page is showing. That's the main reason it's chosen for manuals and workbooks people use while doing something else.
Can I print on the spine of a wire-o booklet?
No. The binding edge is open wire, so there's no flat surface to print on. If a printed spine matters, perfect binding is the format you want.
What page counts work with wire-o?
Pages go in increments of 2 rather than 4, which gives more flexibility than saddle stitch. Very thin documents are better saddle stitched; very thick ones may exceed the wire diameter, and we'll tell you if that's the case.
Is wire-o more expensive than saddle stitch?
Yes — it's a hand-finished process with more material and more labour per copy. It's chosen for how it functions, not to save money.
