Ultra-high-speed laser printers have been used for production printing, and have recently been extended to ondemand printing where higher resolution printing with an offset press is required. Therefore, developing an optical scanning system that provides a higher scanning rate is necessary. A 20-channel edge emitting laser diode array emits high output power for the purpose of increasing the scanning rate. As the beams for scanning increase, their positional errors become critical. Therefore, higher resolution lenses, which are stable against thermal variation, are also required for the system.

An example of an optical scanning system using 20-channel edge emitting laser diode array and some optical techniques for higher resolution are introduced.

  • For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
