Evaluation of Legibility for Color Texts
Abstract:This paper describes an investigation on the legibility of color texts. We concentrate on line reproduction quality and modulation transfer function (MTF) of Y data in CIE XYZ color space of original images, and study the correlation between legibility and each of these two characteristics in order to develop an objective evaluation method. We begin by preparing samples of test targets of various colors. Then the line reproduction quality and MTF are measured and the legibility is evaluated subjectively for comparison. As a result, we have found that we can predict the legibility of color texts even on color background by the use of these two characteristics.

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.
