We have developed a new 1200 dots-per-inch (dpi) light emitting diode (LED) print head for high-quality digital color printers in the next generation. The LED print head is suitable for high-speed color printer print heads. In order to achieve the high performance of the LED print head, we have developed an original 1200 dpi LED array chip with matrix structured wiring. Moreover, the LED array chip realizes a “Low cost LED print head” in which the number of bonding wires and driver integrated circuit (IC) chips on the LED print head has been decreased to less than half, compared to the conventional 1200 dpi print head.

  • 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.
