When anodising, the aluminium component is anodically treated in an acid electrolyte and the process transforms the aluminium surface to aluminium oxide. The resulting aluminium oxide layer is 15-25 µm thick and possesses capillary-like pores. When individually dyeing anodised surfaces with Anodised Individual, the excellent ability of the pore structure to absorb fluids is exploited in order to fill the pores with special dyes. After dyeing, the pores are closed by means of a chemical reaction that transforms the aluminium oxide to aluminium hydroxide. The anodised layer then formed by this process is extremely hard and wear-resistant.
However, Anodisation Surface Solutions (A.SS) go one step further. They make it possible to create individually customised metallic coatings, not only selecting the colour, but also the entire visual design. Logos, texts, images, consecutive numbers, barcodes, etc. can now be integrated in the anodisation process, accurate in every detail. A.SS make use of a printing process in which the lettering, image or logo are captured in the anodised layer of the aluminium. The dye is therefore not applied to the surface, but integrated and protected within the material. Using state-of-the-art digital printing technology, even photorealistic images and halftone printing as well as colour gradients can be easily implemented. The A.SS process does not require the films and screens normally needed for screen printing and even changing texts, consecutive numbering and barcodes can be reproduced.
