Torus’ Z345 is the world’s first Automatic Colour Inspection System powered by X-Rite®. Providing true quantitative colour measurement for aluminium and steel beverage cans in an automatic system.


The Z345 is capable of inspecting 202-300 body diameter, straight walled and finished cans with minimal change parts. Cans may be loaded in any orientation, either on to an automatic in-feed conveyor or directly from the production line. A high-resolution colour scan camera reads and ‘unwraps’ the label and aligns it to a master image. The can is then accurately presented to the Ci64 for inspection at pre-defined, user selected locations with unmatched positional repeatability.
