  • Method and apparatus for printing multicolored container body blanks in a single pass
    Patent number: 5339731
    Abstract: A method and apparatus are provided for printing individual metal body blanks, from which three piece container bodies are formed, in a multi-colored image on an individual body blank basis. Individual body blanks are cut from a sheet and fed in two parallel streams to the rotating impression cylinder of a multi-color off-set litho press. The body blanks are secured to the impression cylinder using mechanical clamps and magnets and are rotated sequentially past a number of inking unit/ultraviolet lamp pairs. As each color ink is applied by an inking unit, it is immediately cured by an adjacent ultraviolet lamp before the body blank is transported to the next inking unit.
