Drop Placement Error Analysis for Ink Jet Deposition
Abstract:Most industrial and commercial applications for materials deposition in a digital format call for a high degree of accuracy to satisfy the output requirements. Ink jet deposition has the potential to meet the requirements by delivering a consistent volume at a precise location in time and space. Currently available ink jet print heads employ multiple jets to enhance throughput and either the print head or the substrate is scanned relative to the other to complete the desired coverage. The timing and order of initiating jet channel firing is controlled by electronics and software, however, differences in flight time of the drops from the nozzle exit to the substrate can result in significant drop placement error. The difference in flight time is due to manufacturing tolerances that include channel-to-channel differences in print head geometry, materials, and drive electronics. A set of dimensionless parameters has been developed that describe drop placement error based on theoretical input as well as experimental data. Using a drop ejection visualization system, it is possible to measure drop flight time and other parameters that characterize the jetting behavior under realistic conditions. Theoretical calculations and experimental results for predicting the drop placement error due to the print head will be presented.

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.
