While it is common that office solid ink printers utilize multiple drop sizes to produce different printing resolution modes, recently a system has been introduced implementing multiple drop sizes in a single printing mode. The advantage of this mode is in its higher image view quality at speed, which will be shown in some detail. Additionally, developmental particulars of this dynamic drop size switching, or DSS, print mode will be discussed. DSS printhead geometry will be presented together with an overview of the physics of multiple drop size ejection. With a system physically capable of DSS printing defined, a discussion of system implementation will follow. This discussion will include an analysis of the pertinent view quality and reliability requirements for the printing system. These requirements will be discussed as will the means found to meet them. Perhaps the most significant of these is the means by which jetting robustness goals were met through the use of a unique halftoning algorithm, which will be covered in detail. The paper will conclude with view quality comparisons of the solid ink DSS mode currently in the marketplace to a single drop mode of similar speed and another of similar view quality.

  • 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.
