Abstract
A layer of additive material is formed in a circular printing area on a substrate using additive sources distributed across a printing zone. The additive sources form predetermined discrete amounts of the additive material. The substrate and the additive sources are rotated with respect to each other around a center of rotation, so that a pattern of the additive material is formed in a circular printing area on the substrate. Each additive source receives actuation waveforms at an actuation frequency that is proportional to a distance of the additive source from the center of rotation. The actuation waveforms include formation signals, with a maximum of one formation signal in each cycle of the actuation frequency. The formation signals result in the additive sources forming the predetermined discrete amounts of the additive material on the substrate.
