The patent US12043045B2 outlines a method and control system for printing images on curved surfaces using at least one drop-on-demand printhead. The method involves positioning the printhead at two adjacent locations with different orientations relative to the print path direction. As the printhead and the curved surface move relative to each other, the system determines an overlap area where two swathes of ink will intersect. This overlap area is crucial for ensuring that the inkjet drops are applied at optimal angles of incidence, which is essential for maintaining print quality. The method also includes selecting a stitch point within the overlap area to minimize differences in dot pitches between the two printhead positions, thereby ensuring a seamless transition in the printed image.

Additionally, the patent specifies that the control system comprises a processor that facilitates the determination of the overlap area and the angles of incidence for inkjet drops. The system can accommodate configurations where the two adjacent printhead positions may correspond to different passes of the same printhead or involve two distinct printheads. The claims further detail that the printheads can have equal or different nozzle pitches and orientations, allowing for flexibility in design and application. Overall, this innovation aims to enhance the quality and consistency of printed images on curved surfaces by addressing the challenges posed by varying angles and positions of the printheads.
