Abstract
The present invention is embodied in a system and method for producing efficient ink drop overlap filled with a pseudo hexagonal grid pattern. In general, the present invention can include an inkjet printhead assembly that incorporates a preprogrammed correction scheme or schemes [1-n] (herein correction scheme will refer to all applications), for correcting systematic ink drop placement errors of the inkjet printhead. The printing system of the present invention uses a unique ink dot pattern, called a pseudo-hexagonal close pack system. The present invention optimizes the addressable grid for dot placement, pseudo hexagonal close pack system, with an efficient geometry for packing circles to fill an area, similar to the hexagonal close pack system. However, the present invention in creating dots on a non-symmetric grid is supported by available software and is not computationally complex.
