Jet Fluctuations and Drop Velocity Jitter: Confirmation of a Causal Model
Abstract:In continuous inkjet devices, an applied perturbation, such as acoustic vibration or thermal modulation, is used to drive the Rayleigh-Plateau instability to cause regular breakup of liquid microjets into droplets of controlled size. Background fluctuations and other processes contribute to subtle variations in droplet velocity within the droplet stream. These velocity variations—droplet velocity jitter—can be observed by stroboscopy or by laser detection. The fluctuations in droplet position or period are influenced by the details of the jet breakup process, and measurement of the droplet fluctuations as a function of distance along the droplet stream provide estimates of the fundamental noise on the jet.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
