Printing System Optimization via Supplemental Light Colorants

Traditional printing processes usually consist of three basic colorants, i.e., cyan, magenta, and yellow, for their inherent subtractive color nature. Black colorant is sometimes adopted to optimize a printing system between stable neutrality, lower colorant consumption, and achieving higher reflection density. The capability of printing extra color(s) is used in two scenarios: accent colors to precisely matching colors, and light colors, such as light cyan and light magenta, to further enhance image quality. The advantage of adopting light colors to improve print quality such as granularity is its low development cost compared with significantly improving the corresponding complicated fundamental printing process; however, it requires better halftone design, precise supplemental colorant replacement strategies, and imposing an extra cost per page compared with the traditional printing process. We will address this system optimization process by quantifying the overall graininess reduction and its corresponding colorant consumption increase.

  • 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.
