The Quality Plan for the Manufacture of an Ink Jet Print Assembly with 1536 Jets
  DOI :  10.2352/ISSN.2169-4451.2002.18.1.art00039_1  Published OnlineJanuary 2002

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.
