By using digital printing on aluminium with subsequent anodising, we realise a wide range of colour spectra for different applications, e.g. on type plates, in the field of decorative elements, on advertising articles or in the consumer goods sector. Even realistic images, as we know them from photos or graphic illustrations, can be permanently and securely bonded to aluminium.

Your advantages:

  • Individualizable and realistic prints
  • Integration of any colours that can be reproduced by a digital printer
  • Exceptional effects, e.g. colour gradients, neon colours or complex lines
  • Durable and resistant connections
  • Possibility for back injection with plastics

colour anodising and printing on aluminium

Colour printing on aluminium

In this process, the material is first pre-anodised to create an open-pored anodised layer. Afterwards, colour pigments are embedded in these pores by a digital printer, hardened by UV light and then hardened by a further anodised layer. The colour elements are thus firmly bonded to the aluminium component and are thus resistant to acids, impact, shock and scratches.

The possibilities for industry are manifold. Digitally printed aluminium is often found on type plates, scales, panels and fronts as well as on promotional items and in the field of household appliances.
