Custom Exposed Spine Smyth Sewn Sketchbook Printing

Exposed Spine Binding for Art and Design

The exposed spine sketchbook (often referred to as open spine or Smyth sewn exposed) is a preferred choice for artists, architects, and designers due to its superior lay-flat capabilities. Unlike perfect bound books that use glue, this method reveals the structural thread stitching of the book block, turning the binding mechanics into a central design element.

Complete Lay-Flat Functionality

The primary advantage of exposed spine binding is the elimination of the gutter. Because the signatures are sewn together and the spine is left uncovered (often free from adhesive or lightly glued for stability without a cover cap), the book opens completely flat. This allows artists to utilize the full width of the spread for panoramic sketches or architectural drafts without fighting the tension of the binding.
