Monday morning, a conference venue in Parramatta. A client is unpacking 300 stainless steel drink bottles for delegate packs, and she runs her thumbnail over the first logo. Hard. Nothing moves. That logo is laser engraved into the steel itself, and it'll still be legible when the lanyards from the same event are long gone.
That moment, the thumbnail test, is the whole story of branding metal. Metal doesn't take ink the way fabric or plastic does, so the decoration method you pick decides whether your logo survives three years of daily handling or three weeks in a dishwasher. We decorate metal promotional products every week at Promo Punks, and these are the seven methods we run, what each one is genuinely good at, and how to pick the right one for your product.
Metal is non-porous, so ink can't soak in the way it does with cotton or paper. It just sits on the surface. That means every metal decoration method has to do one of two things: bond ink to the surface with specialised formulations and curing, or skip ink entirely and physically change the metal itself through engraving, stamping or anodising.
That split is the most useful mental model you'll get from this post. Ink-based methods give you colour. Surface-altering methods give you permanence. The seven methods below sit at different points between those two.
Laser engraving burns your logo directly into the metal surface, so there's no ink to scratch, wash or wear away. On stainless steel it leaves a clean silver-grey mark with a slightly matte finish that catches the light.
It's the method we recommend for anything that cops daily abuse. Drink bottles, tumblers, multi-tools, bottle openers, BBQ tools, anything that lives in a ute tray or goes through a dishwasher. Sunlight does nothing to it because there's nothing there to fade.
One production reality worth knowing: fine text under about 1mm tall can fill in and turn to mush. If your logo has hairline serifs or a tiny tagline underneath, we'll usually suggest dropping the tagline or scaling the mark up. The engraving is also tone-on-tone, meaning your logo appears in metal colour, not your brand colours. Plenty of clients consider that a feature. It looks earned, not stickered on.
Pad printing transfers ink from an etched plate using a soft silicone pad, which lets it wrap around curved and irregular metal surfaces that flat printing can't touch. It holds tight registration on small areas, which is exactly why it dominates metal pens, keyrings, torches and small hardware.
Strengths worth having: spot colours matched to your brand palette, crisp detail at small sizes, and quick setup once plates are made, which makes it very efficient for runs of a few hundred units and up. The trade-off is print area. Pad printing suits logos roughly up to 60mm across, so it's the pick for a neat mark on a pen barrel, not a wraparound design on a tumbler.
Rotary screen printing spins a cylindrical product (think bottles and tumblers) under a screen so the ink prints around the curve in one continuous pass. It lays down a thicker ink deposit than most methods, which gives you bold, opaque colour even on dark powder-coated bottles.
Go this way when you want a big, loud logo on drinkware. A wraparound print on a 750ml bottle turns the whole product into a billboard, and a properly cured screen print handles everyday handling well. It's a one-to-two colour method at its best, so keep the artwork punchy and simple.
Digital UV printing lays down full-colour artwork and cures it instantly under ultraviolet light, which means gradients, photographic detail and multi-colour logos are all on the table. A white under-base layer goes down first on dark or raw metal so your colours sit bright instead of ghosting into the surface.
It's also the only method here that handles variable data economically. Want each of 200 staff bottles printed with an individual name? UV print does that in one run. The cured ink has a slightly raised texture you can feel, and it suits products that live indoors or in a bag: desk items, tech accessories, gift drinkware.
An epoxy dome is a full-colour printed decal sealed under a clear resin bubble, giving you unlimited colour protected behind a glossy, slightly 3D lens. The resin is doing real work here. It shields the print from keys, coins and fingernails, which is why domes are the standard for metal keyrings, badges and trolley tokens, the stuff that rattles around in pockets for years.
Domes cost more per unit than a flat print because there's an extra production stage, but a keyring is a multi-year product and the dome is what keeps it looking sharp for that whole run. Quality matters with this one. A properly mixed and cured dome stays crystal clear; we won't run them any other way.
Anodised aluminium carries a coloured oxide layer that's part of the metal itself, and laser engraving removes that layer to reveal bright silver underneath. The result is a high-contrast logo on a coloured product, with zero ink involved anywhere.
This is how you get a red, blue, black or green product with permanent branding. Torches, carabiners, bottle openers and aluminium drink bottles all come anodised in a solid colour range. Because the colour is an oxide layer rather than a coating, you get colourful product plus engraved permanence in one hit. For outdoor gear in brand-adjacent colours, it's hard to beat.
Die striking stamps your logo into metal under serious pressure, then the recessed areas are hand-filled with coloured enamel and often plated in gold, silver or black nickel. This is how lapel pins, challenge coins and keepsake keyrings are made, and the finish is closer to jewellery than to print.
It needs custom tooling cut for your design, so lead times run longer than the other six methods, typically several weeks rather than days. The payoff is a product people genuinely keep. We see die-struck pins from ten-year-old campaigns still turning up on conference lanyards. If the product is meant to mark a milestone, an anniversary, or membership of something, this is the method.
| Method | Colours | Durability character | Best suited to |
|---|---|---|---|
| Laser engraving | Tone-on-tone (metal colour) | Permanent, part of the metal | Bottles, tumblers, tools, outdoor gear |
| Pad printing | 1-4 spot colours | Good for everyday handling | Pens, keyrings, small curved items |
| Rotary screen print | 1-2 bold colours | Thick cured ink layer | Large logos on drinkware |
| Digital UV print | Full colour + gradients | Cured finish, suits indoor use | Detailed art, names, tech items |
| Epoxy dome | Full colour under resin | Print protected by resin lens | Keyrings, badges, tokens |
| Laser on anodised aluminium | Silver on coloured metal | Permanent, no ink | Torches, carabiners, coloured bottles |
| Die striking + enamel | Multiple enamel fills + plating | Decades, jewellery-grade | Pins, coins, milestone gifts |
Laser engraving and die striking last the longest on metal because both physically change the metal rather than adding ink on top, so the branding survives dishwashers, UV exposure and years of handling. For full-colour artwork, an epoxy dome gives printed decoration the longest working life because the resin lens physically shields the ink.
The honest way to choose isn't "which is best" but "where will this product live". A bottle that goes to the beach and through the dishwasher wants engraving. A keyring in a pocket wants a dome. A desk gift that needs your exact brand purple in a gradient wants UV print. All seven methods earn their keep; they just earn it in different places.
The product is only half the decision. Artwork files cause more delays on metal jobs than anything else, and the same few issues come up constantly:
Send us a vector file (AI, EPS or PDF) and most of these problems disappear before production starts.
Pad printing usually has the lowest setup cost for a one-colour logo on small metal items like pens and keyrings. Laser engraving is similarly efficient on drinkware and tools because there are no plates or inks to prepare, just calibration per job.
No. Laser engraving cuts the mark into the metal itself, so there's no ink or coating to fade under sunlight or wear away with handling. The logo lasts as long as the product does.
Yes. Digital UV printing handles full-colour artwork including gradients and photographic detail on stainless steel, usually with a white under-base so colours stay bright on dark or raw metal.
Every custom metal job needs per-job setup: plates for pad printing, screens for rotary printing, laser calibration, or tooling for die striking, plus colour matching and quality checks. Minimums exist so that setup produces a consistent, properly finished run, and the upside is more branded product to put to work across events, client gifts and staff kits.
The engraving itself is completely dishwasher safe because it's cut into the metal. Check the product though; vacuum-insulated bottles are often hand-wash recommended to protect the insulation seal, regardless of how they're decorated.
Most decorated metal products run in roughly two to three weeks from artwork approval, depending on quantity and method. Die-struck items like pins and coins take longer, typically four to six weeks, because custom tooling has to be cut first.
