    Coil Binding, aka Spiral Binding

    Coil binding is composed of a plastic or metal coil that looks similar to a spring. the coil is feed through specially punched holes and then is cut to size and crimped to keep the coil from backing out of the holes. Coil binding provides a book that will lie open and flat and is useful for many applications.

    Three pieces of equipment are required for coil binding. A punch is used to create the holes along the edge of the document. Then a coil inserter is used to thread the coil through the holes in the cover. Some shops choose to do this step by hand. Finally the end of the coil is cut to size and then must be crimped to prevent the coil from coming loose from the book. Crimping and trimming of the coil can be done with either crimping pliers or machines that have been specially developed for that function.

  • Offset Lithography

    Indirect printing method, introduced in 1905, in which the inked image on the press-plate is first printed onto a rubber blanket, then in turn offsets the inked impression on to the sheet of paper. This type of printing is based on the concept that oil and water do not mix. Thin aluminum plates are used which have a hydrophilic (water attracting) surface and an oliophilic (oil attracting) area that the ink adheres to.

Coil binding provides a book that will lie open and flat and is useful for many applications.

    Three pieces of equipment are required for coil binding. A punch is used to create the holes along the edge of the document. Then a coil inserter is used to thread the coil through the holes in the cover. Some shops choose to do this step by hand. Finally the end of the coil is cut to size and then must be crimped to prevent the coil from coming loose from the book. Crimping and trimming of the coil can be done with either crimping pliers or machines that have been specially developed for that function.
