A method for forming a combined printhead alignment pattern includes printing a row of spaced blocks which accommodates both the collection of multiple printhead alignment data pertaining to printhead alignment as between a plurality of printheads and the collection of bi-directional alignment data pertaining to bi-directional alignment for at least one particular printhead, each of the blocks being printed in a single scan direction, but with some of the blocks being printed in a first scan direction and a remainder of the blocks being printed in a second scan direction opposite to the first scan direction.
