How domed resin labels are made, step by step in our Hull workshop

Ask ten suppliers how domed resin labels are made and you'll get ten product pages and very little detail. We think that's backwards. The process is the product. Here's exactly what happens in our Hull workshop, from the artwork you email us to the box that lands on your desk.

What a domed resin label actually is

A domed resin label starts life as a flat printed label. It becomes something else entirely once a clear polyurethane resin is poured on top and left to cure into a raised, glass-like bubble. That dome magnifies the print underneath, deepens the colour, catches the light and gives the label a surface you can feel with your thumb.

It is also armour. The cured resin sits between your artwork and the outside world, which is why domed resin labels end up on machinery, vehicles, tools and premium packaging rather than on a leaflet. For the plain English version, see our guide to what domed resin stickers are.

Step 1: your artwork arrives

Everything starts with a file. Send us a PDF or a PNG and we can work with it. Vector artwork is ideal because it scales cleanly, but plenty of customers just send the logo they already have. If you're not sure it's good enough to print, send it over and we'll tell you honestly.

Then we make a free digital proof. You see your design laid out at the real finished size, with the shape and the trim, before anything is printed. This is where a colour gets checked, a crop gets nudged, or a line of text gets made bigger because it would have been unreadable. No printer runs until you say yes.

Step 2: printing in full colour

Once you approve the proof, your design is printed in house in full colour CMYK. Gradients, photographic detail, fine text, tight registration on a logo: this stage decides whether the finished label looks sharp or muddy. Tell us up front if a brand shade has to be right.

All of it happens in Hull. We don't hand your job to a third-party print house, so if a colour needs pulling back, we walk across the room and pull it back.

Choosing the material and adhesive

The print goes onto a self-adhesive material, and both the material and the adhesive are matched to the job. A curved plastic housing has different demands from a flat aluminium panel or the back of a keyring that lives in a pocket. Tell us where the label is going and what it has to survive, and we'll pick the right combination.

Step 3: cutting to shape

Printed sheets are then cut to shape. Circles, squares, rounded rectangles, ovals, or a bespoke die-cut outline that follows your logo. Accuracy matters, because the resin that comes next uses the cut edge to hold itself in place. A ragged edge means a ragged dome.

The same base process branches here into different products. The same printed and cut label can be domed and sold as a custom sticker, fixed to a metal or plastic blank to become a custom keyring, or mounted as one of our nameplates and badges.

Step 4: the polyurethane dome

Now the interesting bit. A clear two-part polyurethane resin is mixed and dispensed onto each label in a carefully measured amount. The liquid flows out towards the edges and surface tension does the rest. It stops at the cut edge, self-levels, and settles into that smooth curved dome.

Too little resin and the dome looks flat. Too much and it runs over the edge. An even, consistent dome across a whole batch is a skill rather than a button press, and it's the clearest difference between a supplier who domes properly and one who doesn't.

Why polyurethane and not epoxy

Both resins produce a dome. They do not age the same way. Epoxy is cheaper, but it yellows and goes brittle under UV light, which is a problem the moment a label goes outdoors or sits in a sunny window. Polyurethane stays clear and stays flexible, so it copes with knocks, weather and years of sunlight.

Step 5: curing

Domed labels cannot be rushed. Once the resin is on, the trays go somewhere clean and stable to cure, because temperature, humidity and dust all affect the result. Move them too early and the dome deforms. Let dust land on wet resin and it's sealed in forever.

Curing is why a domed label takes longer to produce than a flat sticker, and why the finish lasts. That window is built into any lead time we give you.

Step 6: quality check and despatch

Before anything is packed, the batch gets properly looked at. We check the dome height is even, the resin has reached the edges, no bubbles or dust are trapped inside, and the print is crisp from the first label to the last. Anything that isn't right doesn't go in the box.

Then it's packed and sent. Shipping is free on UK orders over 99 pounds. Because everything is made to order with low and no minimum order quantities, you can run a small trial batch, stick it on the real product, and only commit to a bigger run once you're happy.

What this tells you about choosing a supplier

Now you know the steps, you know what to ask. Put these questions to anyone who quotes you:

• Do you make them yourself? Plenty of "manufacturers" are resellers. Ask where the doming physically happens.
• Polyurethane or epoxy? If they won't tell you, assume it's the cheaper one.
• Do I get a proof before print? A supplier who prints straight from your file is gambling with your money.
• What is your minimum order? High minimums usually mean your job is batched in with someone else's.
• Can I see a sample? Dome height and clarity are almost impossible to judge from a photo.

Frequently asked questions

How are domed resin labels made?

Your artwork is printed in full colour onto a self-adhesive material, cut to shape, then coated with a measured drop of clear polyurethane resin. Surface tension pulls it into a smooth dome, which cures hard before the batch is checked and despatched.

What resin is used for domed labels?

We use a clear two-part polyurethane resin. It stays clear and flexible and resists yellowing under UV light, which makes it a much better choice than epoxy for anything used outdoors or kept for years.

How long do domed resin labels last?

The cured dome shields the print from scratches, moisture and sunlight, so a domed label outlasts the flat sticker it replaces. On vehicles, tools and machinery they stay legible long after an ordinary label would have faded or lifted.

Are domed resin labels waterproof?

Yes. The resin seals the printed surface, so rain, washing and damp are not an issue. Matched with the right adhesive, they cope with outdoor use and with equipment that gets handled and cleaned.

What is the difference between a domed sticker and a normal sticker?

A normal sticker is a flat printed film. A domed sticker has a raised clear resin layer on top, adding depth, gloss and real protection. We compare the two in our post on domed resin versus standard stickers.
