Painted, gilded and printed edges on books, notebooks and cards: how edge finishing is done in production
What edge finishing is
Edge finishing adds colour, metal or an image to the cut edges of a printed item. On a book it is the three outside edges of the page block: the top (head), the bottom (tail) and the side opposite the spine (the fore-edge). On a thick business card or invitation it is the narrow rim around the card. The result is small in area but very noticeable, because edges are what people see when a book sits on a shelf or a card lies on a desk.
Edge finishing has been around for centuries in the form of gilt-edged bibles and ledgers. It has come back strongly over the last few years with special editions of novels, premium notebooks, wedding stationery and luxury business cards. This guide explains the three main techniques, how each one is done in production, which products suit them and what to plan for if you are adding edges to a larger run.
The three main techniques
| Technique | What it looks like | Typical uses |
|---|---|---|
| Painted or sprayed edges | A solid colour on every edge, matte or slightly satin | Business cards, notebooks, special edition books, invitations |
| Gilded or foiled edges | Metallic gold, silver, copper or coloured foil | Bibles, journals, luxury stationery, presentation books |
| Printed edges | An image or pattern across the stacked edge, often a full-colour design | Special edition novels, branded notebooks, collector books |
Painted and sprayed edges
Painting is the most common type of edge finishing. The finished, trimmed items are stacked and clamped tightly in a press so that the edges form one solid surface. The edge is then sanded smooth and coloured, either with a spray gun, a roller or by hand. The clamp keeps the colour from creeping between the sheets.
On business cards and invitations
Painted edges only show properly on thick stock. A 350 gsm card has an edge too thin to make much impact. Duplexed or triplexed cards, where two or three sheets are laminated together into a board of 600 gsm or more, give a visible band of colour. A bright edge against a white or black face is the classic look. Our article on spot UV, foil stamping and embossing covers the face finishes these cards are often paired with.
On books and notebooks
For books, the page block is painted after trimming and before the cover is attached, or after binding for softcover books. Because paper absorbs liquid, the colour slightly soaks into the outer millimetre of each page. That is normal and gives a solid look from the side.
What can go wrong
- Pages sticking together. If the colour is too wet or the stack is released too soon, pages can stick at the edge. Each book is usually fanned after drying to separate them.
- Uneven colour. Rough or uneven trimming shows through the paint. A clean, accurate trim is the foundation of a good edge.
- Bleed onto the page. On uncoated or very absorbent paper, colour can creep further than intended and show as a tinted border on the page.
Since painted edges rely on a sharp, square cut, our guide to guillotine cutting and trim accuracy is useful background.
Gilded and foiled edges
Traditional gilding uses real gold leaf laid onto a prepared edge and burnished to a shine. It is slow, skilled work and is now mostly reserved for fine binding and restoration. In production, metallic edges are applied with foil instead. The clamped stack is sanded and sealed, then a heated roller presses metallic foil onto the edge, much like foil stamping on a cover.
Foiled edges look very sharp on smooth, coated or dense paper. On soft uncoated stock or very thin bible paper the foil can break up slightly, which some people like for an aged look and others do not. Gold and silver are the usual choices, but coloured and holographic foils are also available.
Gilded edges also have a practical side. On bibles and ledgers they were originally used to seal the page block against dust and moisture. On notebooks and journals they help the edges resist dirt from handling.
Printed edges
Printed edges, sometimes called sprayed edges with designs, put an actual image across the edge of the page block: a pattern, an illustration, a logo or text. This has become popular for limited editions of fantasy and romance novels, where publishers print a design that matches the cover.
There are two main approaches. Specialist edge printers use inkjet heads that print directly onto the clamped edge of a book, building up the image across all the stacked pages. The other, older method prints a design partially onto each page near the edge, so that the image appears when the book is closed. Fore-edge paintings, where an image only appears when the pages are fanned, are a hand technique and rarely done in volume.
Printed edges need precise registration and consistent page trim, so they are more demanding than plain colour. Expect to provide artwork to the exact dimensions of the finished page block, including the thickness, which depends on paper bulk and page count.
Which products suit edge finishing
- Thick business cards. Painted edges on duplexed or triplexed stock, often matched to a brand colour.
- Wedding and event invitations. Painted or foiled edges on thick card make a simple design feel special.
- Notebooks and journals. Coloured or gilded edges on sewn or perfect-bound notebooks.
- Special edition books. Sprayed or printed edges on hardcover and premium paperback editions.
- Presentation and award books. Gilded edges for a formal look.
Hardcover books are a natural fit, because the page block is handled separately before casing-in. Our guide to section-sewn hardcover books explains where in the binding process edge work fits.
Planning edge finishing on a larger run
Edge finishing is mostly a batch process with manual handling, which affects timing and cost.
- Allow extra time. Edges are done after trimming and need drying or curing time before the items can be packed. Add a few days to the schedule, more for printed edges.
- Order samples. Paper type changes how colour and foil look on the edge. A short sample run on the actual stock avoids surprises.
- Choose paper with the edge in mind. Smooth, dense papers give crisp foiled and printed edges. Very absorbent paper suits painted edges with a softer look.
- Match colours carefully. Edge colour is mixed paint or ink, not the same process as the printed face, so give a Pantone reference and expect a close match rather than an exact one.
- Plan for overs. Edge work can spoil a small number of items, so the printer will usually run a few extra.
Edge finishing with us
We add painted and foiled edges to business cards, invitations, notebooks and books as part of a full production job. For cards, our business card printing service includes duplexed and triplexed stocks built for edge colour, with edge paint matched to your brand reference. For books and notebooks, we plan the edge work with trimming and binding so the page block is square and clean before any colour goes on.
Tell us the product, quantity, paper and the effect you want, and we will advise whether paint, foil or printed edges will give the best result on that stock and how much time to allow. A sample on your chosen paper is the quickest way to see the effect before you commit to the full run.
