Are you looking for high quality long lasting Photo Anodised Aluminium signs?
Miller’s in house Photo Anodised Aluminium print process produces a superior print result, both in terms of durability and quality. Unlike other printing processes, where the image is printed ‘on top’ of the substrate, we use cutting edge technology printers to embed the image into the aluminium.
Photo Anodised Aluminium is particularly well suited to outdoor signage where maps, photographs, illustrations, text and detailed graphics need to remain clear in demanding environments.
We manufacture interpretive signs and wayfinding for National Parks, botanical, heritage, educational and public-space projects across Australia.
What is Photo Anodised Aluminium?
Photo Anodised Aluminium is a specialist printing process where dyes are embedded into the pores of anodised aluminium and then sealed within the metal surface.
Because the image sits within the anodised layer rather than on top of it, the finished sign has no surface-applied ink or vinyl layer that can peel or flake away.
The result is a smooth, high-quality metal surface suitable for detailed, full-colour signage and long-term outdoor use.

Highest of quality materials to ensure a superior result
The aluminium we use is the highest quality available, imported from Europe and manufactured specifically for our process. The nature of the anodised aluminium means we can embed dyes into the pores of the metal at a consistent depth of up to 25 microns, which results in rich colour and image definition, with unparalleled durability.
