Tab dividers for manuals and reports in volume: tab banks, cut and reinforced tabs, collating and binding
Why tab dividers are a production job of their own
Training manuals, policy binders, product catalogues, tender submissions and audit reports all share one feature: people need to find a section fast. Printed tab dividers do that job. They look simple, but a run of a few hundred tabbed manuals involves more steps than most people expect: a die-cut shape for every position, reinforcement, printing on both sides of a narrow tab, collating each set in the right order and then binding or drilling the whole document.
Getting any of those steps wrong is expensive to fix by hand. A manual with tab 4 in the slot for tab 5, or tabs that sit hidden behind the page edge, has to be taken apart. This guide explains how tab dividers are produced in volume, what decisions you need to make before you send artwork, and where the cost comes from.
Tab banks and tab positions
A "bank" is the number of tab positions running down the edge of the page before the pattern repeats. A 5-bank set has five tabs stepping down the side of the document. A 10-bank set has ten smaller tabs. If your manual has twelve sections and you choose a 6-bank set, tabs 7 to 12 repeat the positions of tabs 1 to 6 on a second pass.
The choice comes down to how many sections you have and how much text each tab needs to carry.
| Bank | Tab size on an A4 page | Suits |
|---|---|---|
| 5-bank | Large, room for a short title | Short manuals, reports with a few main sections |
| 8-bank | Medium, a word or two | Most training and policy manuals |
| 10 to 12-bank | Small, best for numbers or a single short word | Long manuals, A to Z indexes, monthly sections |
Exact tab dimensions depend on the die your printer uses, so ask for a template before you start designing. Tabs can also run along the top edge, which is common for landscape documents and files that sit in a drawer.
Extra-wide dividers
Standard A4 tab dividers are slightly wider than A4 so the tab sticks out past the pages. If the manual uses plastic sheet protectors, the tabs will be hidden behind them unless you order extra-wide dividers. This is one of the most common mistakes in binder projects and is worth checking before anything is cut.
Materials and reinforcement
Tabs take more wear than any other part of a manual. They are grabbed, pulled and bent hundreds of times. The material decides how long they last.
- Card, 250 to 300 gsm. The usual choice for printed dividers. Prints well on digital and offset presses.
- Card with laminated or reinforced tabs. A clear film is applied over the tab area, or over the whole sheet, to stop tabs creasing and fraying. Strongly recommended for manuals in daily use.
- Reinforced binding edge. A strip of film along the punched edge stops pages tearing out of ring binders.
- Polypropylene. Plastic dividers are almost indestructible and wipe clean, which suits workshops, kitchens and labs. They print with specific inks and cost more.
Full-sheet lamination is the simplest way to protect both the tab and the binding edge in one step. It also makes printed tab text resistant to scuffing. Our guide to gloss, matte, soft-touch and anti-scuff lamination compares the films.
Artwork set-up for tabs
Printed tab dividers need a little more care in the file than a standard page.
- Use the printer's template. It shows exactly where each tab sits and where the cut line runs. Do not guess from a sample.
- One page per tab position. Each divider in a set is a separate page in the PDF, in the order they will appear in the manual.
- Print both sides of the tab. Readers flip from both directions, so the tab label should appear on the front and the back. The back of the tab is a mirror position, which is another reason to work from a template.
- Bleed into the tab. If the tab has a coloured background, extend the colour 3 mm past the tab's cut line on all sides.
- Keep text short and large. Tab text should be readable at arm's length on a shelf. Numbers or a single word work best on small banks.
- Colour code sections. A different colour per section, carried from the tab onto the divider page, makes navigation easier than text alone.
How tabs are cut
Each tab position is a different shape, so tab dividers are die-cut rather than trimmed on a guillotine. The printer uses a set of cutting formes, one for each position in the bank, or a forme that cuts several positions from one larger sheet. Short runs are sometimes cut on a digital cutting table instead, which avoids forme cost but takes longer per sheet.
Because each position is cut separately, the sheets have to stay in strict order from press to finishing. Good printers mark each stack clearly and check the first cut of every position against the template before running the rest. For more on how formes and cutting work, see our guide to die cutting, kiss cutting and forme design.
Collating, drilling and binding
This is where most of the labour sits. Each manual is a sequence of printed pages and dividers that must be gathered in the right order.
Collating
Machine collators handle mixed stocks, including dividers, but tabbed sheets can catch on feeders, so some jobs are collated by hand or semi-automatically. Every set is checked for count and order. For large runs, a sample from each batch is pulled and flicked through tab by tab. Our article on collating, inserting and kitting explains how this stage is planned and costed.
Drilling for ring binders
Manuals that go into ring binders are drilled after collating. Check whether you need 2, 4 or another hole pattern, and the distance from the edge. Reinforced binding edges are worth it here. Our guide to padding, drilling and round cornering covers hole patterns.
Wire-o and other bound formats
Tab dividers also work in wire-o and coil-bound manuals, which open flat and do not need a separate binder. The dividers are punched with the pages. Perfect binding is rarely a good match, because the tabs stick out past a glued spine and fan unevenly.
What drives the cost
- Number of tab positions. More positions mean more cutting set-ups and more collating steps.
- Reinforcement. Lamination or reinforced tabs add a finishing pass.
- Collating method. Hand collating is accurate but slow, and is charged by the hour.
- Quantity. Die-cut forme costs are spread across the run, so unit cost drops sharply with volume.
- Versions. Manuals with different sections for different departments need separate collating sequences.
Producing tabbed manuals with us
We produce tabbed training manuals, policy binders, catalogues and reports in runs from a few dozen to several thousand sets. Through our booklet and manual printing service we can supply tab templates for 5, 8, 10 and 12-bank sets, print and laminate dividers, collate them with your pages and finish each set drilled, wire-bound or boxed. We check the first set from every batch tab by tab before running the rest, so you do not open a carton to find section 7 where section 6 should be.
Send us your page count, number of sections, the binding you need and the quantity, and we will send back a tab template and a quote. If the manuals will be updated each year, tell us at the start. Planning the dividers so sections can be swapped later saves a full reprint when the next policy change arrives.
