Text quality is a key aspect of overall print quality. Assessing text quality objectively and quantitatively has remained a challenge, despite our longstanding desire to reach this goal. The range of quality attributes is still seen by many as too broad and the definitions too vague and subjective. In this study, we aim to help overcome these obstacles by exploring whether key attributes exist that can be easily quantified and dependably correlated with subjective perceptions of print quality. If such attributes can be found, we believe a simple predictive model can be developed. For insight into which perceived attributes are critical and to help us select and design objective measurement algorithms, we started by conducting a subjective survey. Guided by the results, we performed quantitative stroke quality measurements and found good correlations between basic stroke properties (e.g., blurriness, stroke width and contrast) and the subjective survey results. We also found that text defects introduced complicating factors into the predictive model. This study provides the foundation for a more comprehensive future study.

  • For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
