The Quality Plan for the Manufacture of an Ink Jet Print Assembly with 1536 Jets
Abstract:High-speed digital printing with drop on demand ink jets requires a jet for every pixel. One approach to meeting this need is to construct multiple jet modules that can be aligned to provide high resolution variable printing at widths used in printing labels or even as add-ons to offset printers. Spectra has developed a single jetting assembly or print swath assembly with 1536 jets that prints at 2.5 inch wide, 600 dpi and line speeds up to 100ft/min. The quality plan used to manufacture this print swath assembly to insure 1536 jets are performing to specification will be presented. An overview of the print swath design and manufacturing process will be given. The relationship of the product specification to material requirements, to in-process verifications and to the final acceptance test will be shown. The requirements of nozzle assembly parameters and clean room contamination control to resultant image quality will be discussed.

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.
