Abstract
A method for printing includes providing a substrate on which a matrix of color elements is defined, the color elements having respective center lines. A printhead assembly is positioned over the substrate. The printhead assembly includes multiple controllable nozzles. At least one of the substrate and the printhead assembly is translated so that the printhead assembly scans over the substrate in a scan direction transverse to the center lines of the color elements. Droplets of ink are ejected from the nozzles onto the substrate at selected times while the printhead assembly scans over the substrate. The times at which to eject the droplets are selected so as to cause the droplets to land on the color elements at respective locations, such that respective locations are displaced from the center lines.
