Abstract
Provided herein is a head unit arrangement method for arranging a plurality of head units in a liquid droplet ejection device that plots an image in a matrix form with functional liquid droplets in a number n of colors by performing the number n of primary scans and a number (n−1) of secondary scans. The head unit arrangement method includes evaluating liquid droplet ejection performance of each of the head units based on an inspection result of a volume of liquid droplet ejection from each of the functional liquid droplet ejection heads to arrange two of the head units that exhibit the lowest liquid droplet ejection performance at both ends in the Y-axis direction.
