Tilted Printhead Arrangement on Printbar Beam for High Resolution

The patent applies dimensionality change by tilting the printhead relative to the printbar axis, transforming the traditional orthogonal arrangement into an angled configuration. This angular dimension allows nozzle rows from multiple printheads to overlap and contribute to the same print zone, effectively increasing the printbar native resolution without requiring multiple printing cycles. The tilted arrangement enables higher resolution in a single pass, resolving the contradiction between image resolution and throughput.

By introducing an angular dimension through printhead tilting, the patent enables multiple nozzle rows to converge on the same print zone in a single printing cycle. This eliminates the need for sequential printing passes, thereby removing the source of cross-print placement errors and artifacts. The single-pass printing achieved through angular arrangement ensures consistent placement accuracy while maintaining high resolution.

The patent changes the angular parameter of printhead arrangement from the conventional 0 degrees (orthogonal to printbar) to a specific tilted angle. This parameter change enables the overlapping nozzle rows configuration that increases printbar native resolution. By optimizing the tilt angle, the system achieves higher resolution while managing the complexity of the arranged configuration, as the angular parameter provides a systematic way to control the overlap and coverage.
