Long-life, weather-resistant UV-printed ACM and dibond panels for exterior signage, architectural cladding, wayfinding, and permanent display installations.
Request an ACM Panel QuoteAluminium composite material (ACM) — the category that includes dibond, alucobond, reynobond, and equivalent products — offers the combination of properties that permanent exterior print applications demand: dimensional stability, weather resistance, a smooth UV-printable face, and manageable weight for large-format installation.
UV printing directly onto the aluminium face produces sharp, photographic-quality results that, with appropriate coating, hold their colour for 10+ years in exterior environments. For building identification, wayfinding systems, architectural graphic cladding, and any signage application where longevity justifies the premium over foam board or paper-based substrates, ACM is the specification of choice.
UV-printed ACM with protective coating maintains colour stability for 7–15+ years outdoors. Aluminium doesn't absorb moisture, warp, or delaminate — unlike wood, foam, or paper substrates.
The composite construction provides exceptional flatness at scale — critical for large-format precision work where panel bow or print registration errors are unacceptable.
Smooth aluminium face produces photographic-quality UV output — consistent, sharp, and accurate to brand colour specification across multiple panels in large installations.
CNC cuttable, routable, V-grooveable for folded returns, and drillable. Panel fabrication into box signs, cladding cassettes, or custom shapes is done after print for dimensional accuracy.
| Specification | Standard Options | Notes |
|---|---|---|
| Thickness | 2mm, 3mm, 4mm | 3mm is the most common for signage; 4mm for larger panels and structural applications |
| Face material | Pre-painted aluminium (various colours) or mill finish | Pre-painted white is standard for UV printing background; other colours available |
| Core material | Polyethylene (PE) or fire-resistant mineral (FR) | FR core required by building regulations for use above ground floor on facades |
| Standard panel sizes | Up to 1500mm × 4050mm | Custom sizes and gang-printing of multiple panels per sheet available |
| Protective coating | Gloss, satin, or matte UV-stable clear coat | Required for exterior applications; optional for interior use |
| Fabrication | CNC cut, V-groove, drill, fold | Typically done after printing to ensure dimensional accuracy of finished panel |
Fire-resistance note: Building regulation requirements for facade cladding materials vary by jurisdiction and building type. If ACM panels are to be used as building cladding, confirm fire-resistance requirements for your specific application — FR core panels may be mandated. Polyprint can advise on specification.

The aluminium face provides a smooth, weather-resistant surface ideal for UV printing. Standard thicknesses are 2–4mm. It is the primary substrate for permanent exterior signage worldwide.
With UV-stable inks and protective coating, UV-printed ACM maintains colour fidelity for 7–15+ years under typical weathering conditions. The aluminium face doesn't warp, absorb moisture, or delaminate — making it significantly more durable than foam, wood, or paper substrates in exterior environments.
Yes. UV-printed ACM can be CNC cut, routed, V-grooved for folded returns, and drilled after printing. Fabrication is done after print to ensure the printed area aligns precisely with the finished panel dimensions. Polyprint can supply flat printed panels for your fabrication or coordinate fabrication as part of the project scope.
A UV-stable protective clear coat applied over the UV-printed surface extends colour life and scratch resistance for exterior applications. Gloss, satin, or matte finish options are available. Polyprint specifies coating type and thickness to match each project's environmental exposure and expected service life.
Building regulation requirements vary by jurisdiction and building type. Above ground floor on facades, FR (fire-resistant mineral core) ACM is often mandated. Polyprint can advise on specification requirements for your application — share the building use, height, and location, and we'll confirm the appropriate core material.
