A Guide to Book Edging 

Book edging is a trendy way to give books a unique, high-end look. Whether you’re aiming for something bold, elegant, or completely custom, adding color or design to the edges of a book block can make a big impact. If you’re thinking about incorporating this trending technic into your next project, here’s your guide to Book Edging!

What is Book Edging?

Book edging is the process of adding color, patterns, or detailed designs to the outer edges of a book’s pages. This technique is used to make a book stand out, or align with a specific brand or theme. There are three main ways to achieve this effect: manual, automatic, and digital processes. The right choice depends on the level of detail you need and your budget.

Three Ways to Print on Book Edges

1. Manual Process 

First, the edges are sanded to ensure the paint or ink adheres properly.

Two main techniques are used:

  • Spray painting – Best for solid, single-color edges.
  • Silkscreen printing – Allows for single or multi-color patterns.
  • Since this method takes time and skill, it’s usually outsourced to specialist printers.
  • Works well for custom book edges and card decks.
2. Automatic Process 
  • Like the manual process, edges are sanded before applying paint.
  • Uses an automated spray system to apply a single solid color.
  • Great for book edges and card decks when you need a quicker turnaround.
3. Digital Process  

If you want detailed, multi-color designs, digital book edging is the best choice.

  • Unlike the other methods, sanding isn’t always necessary as long as the edges are neatly trimmed.
  • Uses inkjet printing to apply full-color, highly detailed designs.
  • Ideal for premium book edging projects.

How the Edging Process Works

No matter which method you choose, the process generally follows these steps:

  1. Securing the Book Block – The pages are tightly clamped together to prevent movement.
  2. Prepping the Surface – If needed, the edges are sanded for a smooth, even application.
  3. Masking – Any areas that shouldn’t be painted are carefully covered.
  4. Applying Paint or Ink – This can be done using brushes, rollers, spray systems, or inkjet printing.
  5. Drying – Paint or ink is dried quickly using air blowers or heat guns to prevent smudging.
  6. Final Check & Clean-Up – The edges are inspected for quality, and any excess paint is cleaned up before the book is assembled.

Key Size and Format Considerations

If you’re planning on book edging, here are some important technical details to keep in mind:

  • Spine width: Between 6.5mm (0.25 inches) and 76mm (3 inches).
  • Book dimensions: Works best for books sized 102mm x 152mm (4×6″) to 228mm x 305mm (9×12″).
  • File specifications:
    • Submit high-resolution PDFs.
    • Use CMYK color mode.
    • Include 3mm bleeds.
    • Each edge requires a separate file.

Things to Consider When Using Bleeds

If your book design has bleeds (where ink or color extends to the edges), keep these factors in mind:

  • Color Consistency: There may be slight variations in large solid color areas.
  • Banding Issues: Sometimes, color banding can appear in the bleed areas.
  • Best Practice: Book edging works best on designs without bleeds to ensure even color coverage.
