Aluminum foil printing typically uses flexo printing. The core of this process is the use of a flexible photosensitive resin plate as the printing plate. An anilox roller precisely controls the amount of ink applied to the aluminum foil. Heat and drying are then performed to solidify the ink, ultimately creating a beautifully printed image.
Aluminum foil packaging is often vibrant and richly colored, requiring multiple overlays.The aluminium foil printing machine employs multiple printing units arranged in sequence (e.g., red, yellow, blue, black, and spot colors). The foil passes through each unit, overprinting each color individually to create a complete, full-color image. Registration accuracy is crucial.
