The Influence of Print Technology on the Image Quality of Convex Braille Printouts for the Blind

摘要

People with visual impairment and blindness are a significant population in the modern world. Their active and independent participation in society can depend largely on their education, which is greatly enhanced by access to convex print resources. Enhancing image quality while reducing production costs is a dichotomy when developing resources used for the education of people with visual impairment. Due to rapid technological progress, analyzing the influence of technology on the quality of convex printing is justified. This paper will describe: 1. traditional and novel methods of manufacturing convex prints, 2. an analysis of the influence of production method on Braille character quality, 3. the results of preliminary measurements, 4. suggestions for the further development of particular technologies.
