System and method for producing efficient ink drop overlap filled with a pseudo hexagonal grid pattern

A method for producing ink drops that efficiently overlap one another, comprising:

• creating addressable pixel locations of the ink drops;
• selectively firing the ink drops on a predetermined subset of the addressable pixel locations to produce a pseudo hexagonal grid pattern;
• and
• providing ink dot misplacement that balances ink dot size to decrease ink and decrease sensitivity to placement error.

An inkjet printhead, comprising:

• a nozzle member with a nozzle array and ink drop generators that create drops of ink of a dot size suitable for creating full area coverage over an N×N imaginary overlay grid when N drops per square inch in a vertical direction and a horizontal direction are printed on a target print medium;
• and
• a programmable scheme coupled to the ink jet printhead for addressing pixel locations at a 2N×N imaginary overlay grid with 2N drops per linear inch in at least one direction, and N drops in another direction, wherein the N drops are printed parallel to the nozzle array and the 2N drops are printed orthogonal to the nozzle array for selectively firing drops on a predetermined subset of the addressable pixel locations such that the resulting pattern of printed drops has a total of N×N drops per square inch;
• wherein the ink drops are placed on an alternating set of odd and even pixel locations in an axis containing 2N addressable locations to create a pseudo-hexagonal drop overlap grid pattern.
