ABSTRACT:
A method of printing spots with high spot placement accuracy using print heads with random/unevenly spaced ejector locations and coarse alignment of the multiple print heads. This is performed by accurately determining the spot positions from all the print heads using a vision system and printing at high addressability. The spot placement accuracy will be determined by the addressability as long as the ejected drop position is reproducible and other system errors are negligible.
