Lateral Merging Continuous Inkjet
Abstract:Continuous inkjet (CIJ) devices that use more than one nozzle to form a single droplet are reported. The experimentally studied devices contain a pair of interactive nozzles that are used to form ink drops with large and small volumes by thermally stimulating a liquid jet at each nozzle, causing controlled breakup. Resistive heaters located around each nozzle are used for both thermal stimulation and for controlling the direction of the ink stream from each nozzle. Under proper conditions, the large drops formed from each nozzle in the pair touch each other and merge laterally, while the small drops from each pair of nozzles remain separate. The lateral merging CIJ system offers a potential for even greater speed advantages and higher image quality than existing singlenozzle Kodak Stream inkjet technology, a continuous inkjet system. Details on design, fabrication, and characterization of the lateral merging CIJ device are provided, including results from experimental studies.

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.
