Applications
Industry, public buildings, luxury: raised marking adapts to every context
From industrial machinery identification to Braille plates in public access buildings, raised marking covers a wide range of uses with a single requirement: permanent legibility, without maintenance, in often demanding environments.
Manufacturer plates, hotel signage, accessible pictograms or safety marking: each application imposes its own constraints on substrate and relief depth, defined from the outset of the project design phase.
Permanent marking — no ink, no maintenance
The plastic deformation of the substrate produces a relief that is inseparable from the material: it cannot peel away, cannot be erased by UV exposure or chemical products, and remains legible after years of intensive use.
- Combined tactile and visual legibility, even under raking light
- No risk of peeling or discolouration during washing
- Compatible with aluminium, brass, stainless steel and engineering plastics
- Can be combined with UV printing or paint-fill

What is the difference between embossing and laser engraving for an industrial plate?
Laser engraving removes material through thermal ablation; embossing mechanically deforms the substrate to create a raised relief. Both processes are permanent, but embossing produces a tactile three-dimensional effect without any material removal. It is particularly suited to Braille, tactile pictograms and prestige plates. Laser engraving is better suited to small one-off runs and designs requiring very fine geometry.
Does raised marking hold up on equipment subject to frequent chemical cleaning?
Yes, provided the correct substrate is selected. On anodised aluminium, brass or stainless steel, the raised relief is unaffected by solvents, industrial cleaning agents or mild acids — unlike printed marking, which can fade progressively. Raised marking requires no additional protection to maintain legibility in these environments.
Can embossing and printing be combined on the same plate?
Yes. The raised relief can be complemented by UV printing or paint-fill in the recesses to enhance visual contrast. This combination is common on manufacturer plates and high-specification interior signage, where legibility must be assured both by touch and by sight.
Is embossing suitable for small runs or only for large quantities?
The process is viable from small runs. The embossing die represents a fixed initial investment, but it is reusable for all subsequent repeat orders, guaranteeing perfect reproducibility from one plate to the next. For strictly one-off pieces, laser engraving may be more appropriate, as it requires no die to be produced.
What files are required for the production of a custom embossed plate?
A vector file in .AI, .EPS or high-resolution PDF format is required for die engraving. All text must be converted to outlines before submission. The accuracy of the source file directly determines the sharpness and fidelity of the final relief. Any blurred or pixelated element in the file will be reflected in the quality of the die.
Embossing, debossing and raised marking: what do these terms actually mean?
A process based on plastic deformation of the substrate
Embossing refers to the creation of a raised relief through mechanical deformation of the material, whilst debossing produces a recessed impression. The term raised marking encompasses both techniques depending on the sector. In every case, the principle is the same: a male die and a female counter-form compress the substrate to deform its structure without removing any material. The resulting marking is permanent by nature — it relies on no ink deposit or film that could degrade over time.
Compatible substrates: metal, plastic and flexible materials
Aluminium, brass, stainless steel and engineering plastics are the most commonly used substrates. Each offers a different balance between mechanical resistance, chemical durability and aesthetic finish. The choice of substrate directly determines the achievable relief depth and the longevity of the marking in the intended installation environment.
Which material for which environment?
Aluminium, brass, stainless steel: distinct properties for specific applications
Anodised aluminium combines low weight with UV resistance, making it the reference substrate for manufacturer plates and exterior signage. Brass offers a premium, naturally corrosion-resistant finish, favoured for door plates and hotel signage. Stainless steel is the material of choice in wet, chemical or high-temperature cleaning environments. Engineering plastics are suited to interior applications where weight and colour take precedence over mechanical resistance.
Industrial applications: identification, traceability and accessibility
Manufacturer plates and equipment identification
Industrial equipment must carry permanent, legible identification throughout its entire service life. Raised marking meets this requirement without maintenance: serial numbers, manufacturer references, safety warnings — the relief withstands vibration, impact and repeated chemical cleaning where printed marking would progressively fade.
Accessible signage and Braille
Buildings open to the public are subject to requirements for tactile and universally legible signage under the Equality Act 2010. Embossing is the reference technique for Braille characters and raised pictograms: the relief is perceptible by touch and visible under raking light, without requiring colour contrast. This dual legibility is particularly valuable in dark or soiled environments.
Embossing or laser engraving: how to choose?
Four criteria to guide the choice of process
Laser engraving is preferable for small one-off runs, very fine geometric designs or thin substrates that are difficult to deform without risk of tearing. Embossing is the right choice whenever tactile output is a functional requirement — Braille, accessible pictograms — or when the run size justifies investment in a reusable die. Both processes can be combined on a single plate to unite fine precision with a three-dimensional effect. In abrasive or chemical environments, embossing on metal offers a structural advantage: no recesses accumulate cleaning residues.
Integration into a signage project: what to plan ahead
Files, substrates and series reproducibility
A precise vector file is the primary condition for a sharp relief that faithfully reproduces the original design. The substrate must be confirmed before the die is engraved, as each material requires specific deformation parameters. Once produced, the die is retained to allow identical repeat orders — an essential advantage for standardised equipment fleets where series reproducibility determines the consistency of marking across the entire installation. In sectors subject to audit, this documentary traceability is a requirement in its own right.
We consistently find that the most successful projects are those in which the choice of process and substrate is integrated from the design phase — before environmental constraints or permanent marking obligations narrow the available options. Anticipating these parameters from the outset is the surest way to guarantee legible, compliant marking throughout the service life of the equipment.
