Abstract:

For patterning images with particular objective pattern resolution by ink-jet printing, some system characteristics should be considered. For example, the physical layout of nozzles usually unmatched with the pitch distance in real fabrication. This article proposed a novel data formatting method based on the manipulation of original image data according to the physical layout and the driving time period of printhead. Through image slicing procedure calculated on rotational pitch, swath times, panel size etc., the original image data will be re-arranged to a format compromised with the drop on demand setting, patterning resolution for vertical and horizontal printing direction, and firing speed. By this so-called interlace-rotation algorithm in this article, the unmatched resolution between the nozzle distance and pixel pitch, it will be bring with together by the calculation of quote and reminder relationship to establish a look-up table, and no resolution loss in printing can be realized. Also, this scheme can operate bi-direction printing in simply conversion method and support user friendly as well as adaptability at plurality of printheads without any change required. This flexibility with compact memory usage will be helpful to mass production with modularized design and large size panel application. Results shown that the printing resolution can be continuous tuning from 100 dpi to 5080 dpi, in consistence and no mura was observed.

  • 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.
