3-Ring
3-Ring binding is a good option for books that must lie open flat. 3-Ring binding is available for 5 1/2" x 8 1/2" size books only.Unlike vinyl binders, 3-Ring binders are padded and allow for full-color printing, making them much more elegant than vinyl binders.
Plastic Comb Binding
Plastic comb binding is also used for books which must lie flat, such as manuals, how-to books, or workbooks.
Plastic Coil Binding
Plastic coil binding is yet another style that is ideal for books that must lie open flat. The main advantage of plastic coil binding is that the book can be folded in half. This binding is similar to wire binding except it's made of more durable plastic.
Wire-O Binding
A Wire-O binding holds the covers and pages of a document firmly in place by a double-loop wire inserted through holes drilled in their left edges. All of the document's pages lay flat when opened, can turn easily through 360°, and stay in perfect registration with adjoining pages.
Saddle Stitching
In saddle stitching - the way most booklets, magazines, catalogs, and calendars are bound - wire staples hold the piece together. A machine drives then through its backbone fold to the centerfold, where they clench. A saddle-stitched printed piece lies almost flat when opened, a convenience for readers.
Perfect Binding
To produce a perfect-bound document, the piece's folded signatures are gathered together in page sequence, clamped together, and placed in a machine that slices about 1/8" off their left edges. Then roughers mill the newly sliced sheet edges to prepare them for gluing. Finally, the edges receive an adhesive application and adhere to a backing.
Tape Binding
This process places a cloth strip of adhesive tape down the bind edge of the book and wraps around about half an inch onto the cover front and back.
