Filed:

Oct 19, 2004

Appl. No.:

10/967990

Inventors:

Richard Florence - Tolland CT, US
Donald Allred - Springboro OH, US

International Classification:

B41J 29/38

US Classification:

347005000

Abstract:

A system and method for optimizing print quality of print media is for use on an ink jet printing system with a drop generator and an orifice plate disposed on the drop generator, wherein the orifice plate comprises nozzles forming a jet array. The drop generator is adapted to modulate ink volume per pixel by adjusting drop generator input voltage or drop generator pulse width. A corona discharge system is also used to form ionized air that contacts with a print media enhancing the wettability of the print media prior to exposing the print media to the drop generator. A controller operates the corona discharge system in tandem with the drop generator to optimize print quality by controlling drop spread and ink film thickness from the printhead onto the print media.

Abstract:

An imaging module includes an ink jet print head for printing human-readable or coded (e.g., bar code) information directly onto various porous and non-porous materials (e.g., a corrugated cardboard container), and a pair of reservoirs that hold the melted ink ultimately used in the printing process. The module also includes an ink feed hopper into which one or more solid sticks of hot melt wax ink are fed and an associated heater to melt the ink sticks in limited volume, together with associated vents, control pumps and valves, all integrated together within the imaging module to deliver the melted ink to the print head for printing on a container or other items.
