SAMBA™ inkjet printheads offer a high nozzle packing density of 1200 nozzles per inch, flexibility to print with multiple drop sizes, and wide ink latitude making them attractive candidates for a variety of inkjet printing applications. In this paper, we offer insight into how these features can be utilized to enable imaging models that provide high image resolution and print speed as well as increased robustness to missing jets, a key element required in single pass printing. We show that SAMBA printheads can be designed to operate in multiple imaging modes and we use simulation and experimental data to analyze their performance. We evaluate multiple imaging models enabled by SAMBA 1200 printheads and compare them for their image quality capability, image artifacts caused by transient jets, and productivity potential for single pass printing. We show that Samba 1200 imaging models combined with over-addressing and grayscale printing offer superior image quality and improved robustness to streaks without compromising on productivity.
