Abstract:
1. A container-printing arrangement configured to print graphic, numeric, and/or alpha-numeric information or an image directly on an external surface of a container comprising a bottle or similar container, said container-printing arrangement comprising: at least one electrostatic print head comprising a housing configured to contain printing liquid therein; said housing comprises a plurality of openings configured to dispense printing liquid in a controlled manner directly onto an external surface of a container; said at least one electrostatic print head comprises a plurality of electrodes, each paired with and disposed adjacent to a corresponding one of said openings; a container handling arrangement being configured to dispose a container adjacent said at least one electrostatic print head to permit dispensing of printing liquid directly onto an external surface of a container; said plurality of openings being disposed such that at least one of said openings is disposed at a greater height than at least one other of said openings; and an arrangement configured to rotate a first of said at least one print head about a machine axis such that a greater centrifugal force is generated at said at least one of said openings disposed at a greater height than said at least one other of said openings such that the difference in pressure in said plurality of said openings between said at least one of said openings disposed at a greater height than said at least one other of said openings being configured to compensate for the difference in the pressure caused by gravity at said plurality of openings of said at least one of said openings disposed at a greater height than said at least one other of said openings.
