RepKover Binding™
RepKover™ binding is a unique process that results in a perfect bound book which when open stays flat. A reinforcing strip is attached to the backbone of the cover with glue being applied only to the edges of the strip. The pages are secured to the strip with two applications of cold glue. This allows the book's spine to flex away from the cover when opended. Lay-flat binding is more flexible than perfect binding and very durable. The entire page is visible as type doesn't get lost in the gutter.
