For most small businesses and hobbyists making single-colour, low-volume labels on packaging, a custom rubber stamp is usually the simpler and cheaper choice. Printed adhesive labels suit full-colour branding, barcodes or batch runs above a few hundred units. The deciding factor is often legal: mandatory information must meet a minimum legibility and permanence standard, and if a stamp cannot meet that, a printed label becomes the only option. A number of suppliers offer stamps built for exactly this kind of decision.
TL;DR:
- Stamps are suitable for low-volume, single-color labels and work best on absorbent surfaces with water-based ink; higher volumes or multi-color branding favor printed labels.
- Legal requirements demand that all mandatory text is legible at a minimum x-height of 1.2mm (or 0.9mm for small packages) and is indelible, regardless of stamping or printing method.
- For surfaces like plastic or glass, fast-drying pigment or solvent-based inks are necessary to prevent smudging, with re-inkable pads offering better control.
- Stamp volume thresholds are around 100 to 200 units per month, above which printed labels with full color, barcodes, or changing data become more practical and compliant.
- Hybrid approaches, combining printed primary labels with stamped batch codes or logos, help balance legal compliance with minimal reprinting costs.

Stamped labels versus printed labels: the trade-offs that matter
Choosing between a stamp and a printed label usually comes down to volume, colour and how the label needs to behave once it is out in the world.
Stamped labels work well for small producers because they need almost no set-up. You buy one stamp, ink it, and apply it directly onto packaging, paper, card or even some plastics. There is no printer queue, no label roll to load and no software to configure. A jam maker stamping use-by dates onto jar lids, or a market trader marking craft bags with a logo, can work through a batch in minutes.
Stamped labels: pros
- Low cost for small or irregular runs, with no printer or software needed.
- Can be applied directly to the product or packaging surface, including curved or textured materials.
- Gives a tactile, handmade finish that many artisan sellers use as part of their branding.
Stamped labels: cons
- Limited to one ink colour per stamp, so multi-colour artwork is not practical.
- Slower once volumes climb into the hundreds, since each impression is manual.
- Impression quality varies if the pad is worn, the ink has dried out, or pressure is uneven.
Printed adhesive labels earn their place when a business needs full colour, scannable barcodes, or variable data such as weights, prices or batch numbers that change from label to label. A printer and label stock cost more upfront, but once set up, output is fast and consistent.
Printed labels: pros
- Full colour and photographic detail are possible, useful for retail packaging.
- Barcodes and variable data can be generated automatically rather than stamped by hand.
- Application can be automated with a label dispenser for higher volumes.
Printed labels: cons
- Requires a printer, label stock and sometimes design software, adding cost.
- Adhesive choice has to match the surface, or labels peel in storage or transit.
- Placement and legibility problems are more likely when labels are applied by hand at speed.
A small bakery selling at a weekend market might stamp batch codes onto bags, while the same bakery supplying a supermarket would need printed labels with barcodes and nutritional information.
What UK rules on packaging and labelling require
Any mandatory information on a label, whether stamped or printed, has to meet a legal minimum for legibility. Gov sets the minimum x-height for mandatory information on prepacked food at 1.2mm, dropping to 0.9mm where the largest surface of the packaging is under 80 square centimetres. X-height is simply the height of a lower-case letter such as “x”, and it is the measurement trading standards officers check first.
The rule that decides whether a stamp works: mandatory label text must reach 1.2mm x-height, or 0.9mm on very small packaging, and must be indelible. A stamp that cannot reproduce that size cleanly, or whose ink smudges or fades, fails the requirement regardless of how good it looks.
Beyond size, the information has to be indelible and sit within a single field of vision so a customer can read it all at once, a point confirmed by food labelling guidance on giving food information to consumers. The Guide to packaging regulations places the duty on packers and importers to mark packages indelibly and legibly, including nominal quantity information.
To check a stamped impression meets these standards, measure the letter height against a millimetre ruler, check the contrast against the background, then run a rub test and a water test to confirm the ink does not smear or lift.
Getting indelible, legible results from a stamp
Reliable stamped labels come down to matching ink to surface and keeping equipment in good condition. Absorbent surfaces such as uncoated card or paper work well with water-based inks, which dry quickly and sit cleanly in the fibres. Coated paper, glass and plastic are non-absorbent and often need a fast-drying pigment or solvent-based ink to avoid smudging before it sets.
- Identify the surface first: absorbent materials take water-based ink, non-absorbent ones need pigment or solvent ink.
- Choose a re-inkable pad for regular use, or a dry pad when you need more control on glossy or plastic surfaces.
- Store pads away from heat and direct sunlight, and re-ink before the impression starts to look patchy rather than after it fails.
- Test durability with a rub test, a water-splash test and a few days of light exposure before committing to a full batch.
- Photograph a test impression next to a millimetre scale and keep a dated record, in case trading standards ever ask for evidence.
Pro tip: Carry a small re-inkable dry pad for non-absorbent surfaces. It gives more control than repeatedly overloading a wet pad, and cuts down on smudging and wasted ink.
Pad maintenance is often overlooked until an impression fails halfway through a run. A dried-out pad gives patchy, pale results that will not meet an indelibility check even if the stamp design itself is correct.
Quick decision rules for choosing a labelling method
Some simple cut-offs make the choice faster without working through every variable each time.
- Under roughly 100 to 200 units a month, with one ink colour and no barcode, a stamp is usually enough.
- Above that volume, or where full colour, barcodes or changing data such as prices are needed, printed labels make more sense.
- Products with strict regulatory requirements, such as prepacked food sold through retail, usually need printed labels that guarantee consistent x-height and indelibility across every unit.
A soap maker selling direct from a market stall can stamp batch numbers onto simple kraft labels. A bottled drink heading into a supermarket needs printed labels carrying a barcode and expiry date that meet the same indelibility standard every time. Many businesses land somewhere in between: a printed primary label carries the legally required information, while a stamp adds a batch code, a signature mark or a quick logo without reprinting the whole run. That hybrid approach keeps compliance intact while avoiding the cost of reprinting labels for small changes.
Notes from testing stamps against printed labels
Tests have been conducted on how different inks behave across paper, card, glass and plastic, including comparisons between ink-tank and laser-based label production covered in a cost comparison of laser versus tank inkjet printing. Those trials consistently show that surface absorbency, more than ink colour, determines whether a stamped impression holds up.
When customers get in touch, the usual starting point is matching stamp size to the x-height the label needs, then choosing an ink colour and pad type that will stay legible on the intended surface. Getting that match right before ordering avoids reprinting or re-stamping a batch later.

Ordering a stamp that meets your labelling needs
If you have decided a stamp fits your labelling needs, the next step is matching the stamp size to the x-height your packaging requires and picking an ink that suits the surface.
- For packaging and product marking, the personalised packaging stamps collection covers common sizes and ink options.
- For return addresses or office use, the personalised stamps range includes address and text stamps in several sizes.
- Replacement pads and inks for existing stamps are available separately, so a worn pad does not mean replacing the whole stamp.
Some suppliers design and make stamps for the UK market, offering advice on sizing before ordering, to help ensure the stamp received meets the legibility your labels need from the first impression.
FAQ
Can a rubber stamp meet legal labelling requirements?
Yes, provided the impression reaches the minimum x-height of 1.2mm, or 0.9mm on very small packaging, and the ink is indelible. If a stamp cannot consistently reach that standard on your packaging surface, a printed label is the safer route for mandatory information.
What ink works best for stamping on plastic or glass?
Non-absorbent surfaces such as plastic and glass generally need a fast-drying pigment or solvent-based ink rather than water-based ink, which can smear before it sets. A dry, re-inkable pad often gives more consistent results than a heavily loaded wet pad on these surfaces.
When should I switch from stamped labels to printed labels?
Once volumes climb past a couple of hundred units a month, or you need full colour, barcodes or data that changes from label to label, printed labels become more practical than stamping by hand. Products facing stricter rules, such as prepacked food sold through retail, usually need the consistency printed labels provide.
Can I use both stamped and printed labels on the same product?
Yes, a common approach is a printed primary label carrying the legally required information, with a stamp added for a batch code, date or quick logo. This keeps compliance consistent while avoiding a full reprint for minor changes.
How do I check if my stamped label will last?
Run a rub test and a water test on a sample impression, and leave another sample in daylight for a few days to check for fading. Photographing the result next to a millimetre scale and keeping a dated record gives you evidence if a regulator ever asks for it.
