To meet the ever growing demands for high quality and high speed digital printing in various commercial and industrial applications, many printing system manufacturers search for high performance, page-wide, digital single pass print engines. This paper describes the development of a high-speed drop-on-demand 12.8 inch wide single pass print engine using Spectra's unique shear mode piezoelectric technology and modular design approaches.It is demonstrated that Spectra's single pass print engine can reliably operate thousands of jets at very high jetting frequencies, making it possible to print at more than 300 feet per minute and at a resolution of 600 by 600 dots per inch. Using the modular design approach, a custommade large format print system can be configured by using multiple 2.56-inch wide print swaths. Such a single pass print engine is capable of printing 100% variable data from one page to the next, providing excellent solutions for high speed, high flexibility and high quality variable data printing applications.
