The technology of digital anodizing reminds the tattooing process when colouring pigments are placed under the skin. It is possible to use such technology only on aluminium because while its anodizing the surface is converted to a transparent aluminium oxide. During formation of this oxide pores are growing.

Special industrial printer injects dye inside pores. Hot sealing is the last operation completing the process of anodizing. Ready element is placed in water with temperature of not less than 96 °C for 40–60 minutes.

As a result of sealing pores are closed with aluminium hydroxide, colouring pigments stay within the aluminium oxide layer and the aluminium surface obtains a number of unique properties. This technology allows to achieve full colour images.
