Recently, resolutions of printing devices are increased rapidly. Obviously, higher density makes better quality for any type of print. In regard thermal printing technology, highest density of mass production printhead is 600dpi except for the particular application of higher density than 600dpi with small quantity. To search the possibility of much higher density by thermal printing method, Kyocera developed 2400dpi and 4800dpi thermal printhead, and made printouts successfully. Printouts by those ultra high density thermal printhead are too small to see by naked eyes. Microscope is required to see it. The other hand, there are issues to solve as thermal printing with this ultra high density. In this paper, future possibility and issues of ultra high resolution thermal printing are introduced. Also the new potential application 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.
