A series of new technologies are described which will enhance printing performance for high demand applications, such as wide format graphic arts printing. Important criteria for this study include: jet density at the nozzle, image quality on the substrate, and total ink throughput.First we will evaluate if the jet density can be doubled from 50 dpi native to 100 dpi native with a single row of nozzles. We will consider such tradeoffs as drive voltage and drop size. These studies are based on laminate carbon array designs.Second, we will investigate how hybrid printhead construction, using Silicon MEMS to form the nozzles, will improve image quality. This analysis will include the straightness capability of a large population of nozzles, as well as the importance of nozzle feature location to improving image quality.Third, we will show how ink throughput is maximized using VersaDrop™ jetting technology. This operating mode will allow the user to select between large and small drop sizes on a pixel-by-pixel basis. This technique provides improved image quality and increased productivity. Additional benefits of the throughput analysis include ink throughput as a function of nozzle packing density and also as a function of power consumption.
