Lay-flat perfect binding, also known as otabind separates the text block and the cover, so that a book can be opened flat on a surface. Durable and easy to use.
This allows the catalogue to open without bending the spine or pulling against it. The space left between the spine and the cover helps avoid the deformation of the book while reading, as all of the pages open fully flat.
An ideal binding for catalogues, magazines, annual reports and books...
You can choose this most commonly used binding option in your projects, which is using adhesive to glue the pages to the spine of the book to make it flexible.
