With the single exception of ISO 13660, there are no generally accepted international standards for describing the image quality of printing systems. ISO 13660 provides simple guidelines for the quantitative measurement of many aspects of image quality for binary, monochrome, printing systems, and has had a significant impact in the printing industry. However, as in most measures of imaging system performance, the visual significance of a measurement difference is not addressed in ISO 13660. This weakness prevents a truly meaningful comparison of printing system specifications. To address this weakness, and to provide evaluation methods applicable to more capable systems incorporating gray-level and full-color imaging technologies, INCITS W1, the U.S. representative of ISO/IEC JTC1/SC28, has been chartered to develop an appearance-based image quality standard. This paper will describe the objectives, the development process, the current status, and the results achieved so far by the many contributors to the development of this standard.
